Title: Who can pop a Containment Circle?
Post by: devonapple on January 31, 2012, 08:03:19 AM
The players made a Containment circle to trap some Malks that had been terrorizing a local park, and were later joined by some Winter-aligned Redcaps. We came to a bit of a disagreement over whether or not the Redcaps (outside the Containment circle) could break the circle and let the Malks out if they had wanted.

Disputes seemed to center around two questions:
Does it merely take free will to pop a containment circle?
Is a Containment circle, intended as it is to keep something in, vulnerable to attack/disruption from outside tampering?

Free will has nothing to do with the cirlce itself.

A circle build to contain something can easily be disturbed by the outside. The redcaps could in fact have destroyed the circle. If it is a special made anti-fey circle this might be something else.

My answer (don't have the book handy to confirm):  Circles, like all thaumaturgy, rely on setting up symbols to channel power.  If those symbols are disrupted the spell is weakened and may fail.  In general, ward type symbols are protected from one side by the ward itself.  The other side of the ward is open (usually).

A simple circle with a rating equal to Lore might be disrupted by anything breaking the circle.  A more extensive ward might have several keystones, runes, or other symbols to break for complete failure.

It was a fae-specific containment circle, baited for Malks (that was one of the Lore declarations, anyway). Two PC Wizards, a tactical/ward specialist and a fae lore specialist, collaborated in its construction

Was it specifically made to keep Fae in and out? That sort of thing would probably need to be declared beforehand...
Title: Re: Who can pop a Containment Circle?
Post by: devonapple on January 31, 2012, 05:38:10 PM
It was definitively meant to keep Fae in (and I was going to give it a chance to inadvertently trap some rival Summer Court Dryads as well, but opted not to).

In future, should one want to make a circle to keep things in *and* out, that would be the equivalent of two separate circle rituals, I guess?
Title: Re: Who can pop a Containment Circle?
Post by: UmbraLux on January 31, 2012, 05:52:33 PM
Yeah, I'd either split shifts between the two or make it two separate rituals.

In the books, you need Free Will before you can break a circle.  For example, in Ghost Story:
(click to show/hide)
.

Another example: in the first book, Harry goes into his inscribed summoning circle (i.e. one meant to contain what's summoned) and Mr. Toad demon couldn't cross it to get to him.

Why does a magic circle work this way? Because either way you look at it, a circle is a threshold.  It divides the world as "things inside the circle" and "things outside the circle" with the circle as the threshold that defines which is which.  Cross the threshold and you are changing your definition of "this" to "that".

In the game system... Circles aren't very well defined, but I would still go with them working both ways.

This can also be explained by the distinction between the directional 'facing' of the circle.
That circle was closed with the express intent to keep something OUT, but we don't really know whether it would have been able to simultaneously keep anything IN (assuming that that thing would have been stopped by a circle at all).

Free will has absolutely nothing to do with, even a falling leaf can break a circle

Post by: polkaneverdies on February 02, 2012, 07:18:03 PM
"directional facing" of the circle doesn't seem particularily relevant in the standoff in Turncoat.
A circle is formed to keep the tongues out. Person inside is warned not to shoot  out or it will break the circle.

On the other hand a mortal on the outside of the same circle can threaten to break it with a piece of gravel.

I would say that free will or a large amount of power are necessary.

The point was whether or not something that would be stopped by the circle if it were 'faced' in the appropriate direction would be affected by an otherwise identical circle 'facing' in the direction opposite theirs
ie. if a creature identical to one currently trapped inside a circle would be able to break that circle from the outside

that issue seems to have been resolved with the reference to Ghost Story, but I don't have my books handy, so I can't check the details for myself

As for creatures without Freewill being able to mar a circle, reread why Binder's minions couldn't do that in Turncoat.

As for facing, there is 'in' and there is 'out' and a threshold between them.  If you can't cross the threshold it doesn't matter which way you were going.

Jim has written a few posts about magic circles and what can (and can't) break.  If you search through his transcribed interviews on the WoJ board you can find more on how magic circles work.

It's not about free will. Binder's minions were spectral. It's about physically breaking it. Random bits of debris has no free will, and yet Harry makes sure to clear off his circle in his lab before he runs a spell.

Free will is irrelevant. It's whether something is physical, or primarily spectral. If you're fueled and made up of magical energy, you can't break a circle.
Title: Re: Who can pop a Containment Circle?
Post by: Richard_Chilton on February 02, 2012, 08:03:54 PM
They were physical - they had bodies made of ectoplasm.  They could punch people, kick people, pick up things, move things - but they couldn't break that circle.

Free Will is required to take an action that will break a circle.

Environmental effects (wind, snow, etc) can break a circle, but there is a WoJ to the effect that someone lacking freewill couldn't kick over a can of paint so that the paint runs into the circle (breaking it).

Here's another example: The Erlking is a major being with earthshaking power, but when Harry bound him the Erlking couldn't stamp on the ground so hard that it shook in a way that would disrupt the circle. The Erlking might (or might not) have been able to force his way through the circle but if he couldn't force his way through mystically then there is nothing he can do to damage it physically.

I feel that is still consistent with the facing issue. In this situation, a person was protected against supernatural threats by a circle and told not to shoot out, we see circle exclusivity, in which mortals could break the circle, inside or out, but spiritual/summoned creatures could not do anything from the facing side. We don't have data about whether a spiritual/summoned creature on the *inside* facing of the circle could cross it, but we know that later in the scene, spiritual/summoned creatures who are suddenly trapped inside an inward-facing circle, they get cut off and disappear.

Free will is irrelevant. It's whether something is physical, or primarily spectral. If you're fueled and made up of magical energy, you can't break a circle.

I think this is what I'd most likely go with.

Also, the circle's purpose matters, I feel. There are Ward circles which are designed to keep something out or protect an object from an effect. Then there are Containment circles to keep something in.

That said...
Environmental effects (wind, snow, etc) can break a circle, but there is a WoJ to the effect that someone lacking freewill couldn't kick over a can of paint so that the paint runs into the circle (breaking it).

Hrmmm... so even if Binder ordered a summoned goon to throw a chair at a Circle, the goon wouldn't? Was the WoJ clear as to whether the cause was prevented, or the effect?

Ectoplasm =/= physical, for the purposes of a circle. They're made, and fueled, by magic, not physical beings.

The Erlking couldn't shake the ground to break the circle through outside effects because the circle blocks magical effects from leaving the circle. Any earth shaking he could have done would have been limited to the area inside the circle. It'd be like trying to call for help from inside a sound-proof booth. Plus, it was a circle specifically made to contain him.

Alas, the first few books have numerous elements which are later contradicted in the fiction as Butcher refined the way he handled the supernatural state of things in Harry's world (there is a WoJ acknowledging this) which generally means that the first 2-3 books should be discounted as "canon" for a discussion such as this.
Title: Re: Who can pop a Containment Circle?
Post by: polkaneverdies on February 02, 2012, 10:56:27 PM
The contradictions aren't limited to the first couple of books. They are simply more numerous there.
 In my experience examples from the first couple books tend to be treated like canon-lite instead of being completely disregarded.
When there are clear contradictions with more recent texts they are dismissed, but if there aren't I wouldn't suggest assuming that they are wrong.

Like many WoJs it was short of details.

And I currently can't find it.  I know I saw it on the forum a year or more ago, but since the WoJ section became its own board I'm having bad luck finding things.

I'm not talking about using a magical effect on the circle.  I'm talking about bringing his foot down with incredible force on the earth inside of the circle, enough force to cause the ground to split - which would break the circle.  The Erlking can toss a car around and perform other vast displays of strenght, but he can't perform an action that can physically break an active circle.

Perhaps the circle renders the ground as impenetrable to the Erlking as the circle is. Breaking the circle by stomping the ground is as antithetical to the expectations of a Circle as a spirit burrowing out of it would be. (In short, I'm agreeing with you on this example, Richard, just not the one in the Spoiler blocks earlier)

The novels are a bit inconsitent on this subject, and the rules are a bit vague.  (Or nonexistent?)  Therefore I pull the following out of nowhere in an attempt to capture the spirit of the latter portions of the series, purely as a house rule (this actually derives from a previous discussion found at http://www.jimbutcheronline.com/bb/index.php?action=post;topic=30822.15;last_msg=1306527):

Create the following hypothetical new stuntlike power:

Empower Magic Circle [-1]  The character adds the Empower Magical Circle trapping to their Lore skill.  This trapping allows the character to make a Lore declaration to change an existing scene aspect such as "Circle drawn in chalk" into a special scene aspect such as "Magic Circle drawn in chalk" -- and have it be true.  [Optionally, the GM might decide that the character can spend one mental stress to cause the circle to be treated as a threshold with a rating of half the character's Conviction (round up, minimum 1)].

Discourage anyone from actually buying this power/stunt (except spellcasting characters, who are considered to have it for free), but allow it to be 'borrowed' in accordance with the Temporary Powers rules (YS92) by spending a Fate point.  Once used, the scene aspect is treated as a 'fact' that triggers compels against the high concept of creatures that are affected by magic circles as described below.

If any creature breaks the circle (by penetrating the barrier, either personally or with an object), the circle is disrupted and the scene aspect is removed.  However, if circle was disrupted by a creature possessing supernatural (or magical) powers, their powers are temporarily weakened: attach the aspect "Violated a Circle" to the creature to represent this.  This aspect can be tagged/invoked for a bonus against any use of the creature's powers (for example, resistance against spells cast by the affected creature or attempts to injure a creature with supernatural armor).  Those inside the circle can break it freely with no adverse effects (other than the circle breaking).

Note that all of this is a long-winded way of saying that the player can do something to make a special declaration (justifing a creature-appropriate high-concept compel) and perform a scene maneuver (that conditionally penalizes powers) for the cost of a Fate point and an action.

Specifying that non-mortal creatures with material bodies 'can' buy off the compel is entirely unnecessary.  ANY character with sufficient available FP can buy off ANY compel.

While I agree that that is what the mechanics say, I guess I'm basically saying that this is a non-standard compel.  After all, my understanding is that purely supernatural creatures (such as ghosts) cannot pass magical barriers, no matter how much Fate they have to spend.
Quote from: YS230
Some beings—especially those of pure spirit—cannot cross a threshold, since they’re usually using their magical power to hold their material world body together. If they cross a threshold without counteracting it, they just… melt.
Such a creature who had access to an acceptable way of countering the circle could do so; this would probably work like a maneuver to remove the circle (at which point there is no circle to stop them from doing as they please any way...)

A sufficiently advanced understanding of Compels resolves this issue.
Buying off a Compel does not necessarily indicate that the Compelled event does not occur, or that the Compelled restriction does not apply, but only that, for some reason, it does not negatively impacted the character.

If you are a spiritual creature and you get invited into a house the threeshold doesn't matter. And if the threeshold is weak then you can force your way through if you have enough power.

#and if a demon/erlking could break a circle by just stomping their foot then there wouldn't be such containmend circles. The existence of them shows that this is not possible. All the power of the beeing is stoped at the edge of the circle.

For the Storm Front example. I think Bob tossed him the bottle, he broke the circle and then Harry drank the potion to escape - no contradiction there.

I disagree.  Purely spiritual creatures - ghosts, spirits - cannot force their way across a threshold.  In Grave Peril the super ghost couldn't break through thresholds - it had to use the "you leave this world when you dream" trick.  And in GS

Again, I'm not talking about projecting their power at the circle itself but at the environment and letting nature take its course.

Let me break it out.  We both agree that Demon Sorcerer can't cast an erase spell on the circle.  The point where there's some dispute on purely physical actions that are directed at the area bounded by the circle.

For example, Harry's summoning circle is in concrete.  If you apply a huge force to concrete (by standing your foot with beyond human strenght) it will crack with the cracks spreading out from the impact point.  Thus the cracks could spread to the binding circle itself.  Cracks in a circle renders it useless (unless they were there and forming the circle when you empowered it) which means that a demon could not have stamped his hoof that hard on concrete - otherwise he would have broken the circle and (lacking freewill) he cannot do that.

You need leverage to break Concrete like that with sheer pressure. You need something holding you down so that all of the force generated by your pushing is going into the concrete and not being absorbed by your own body. Strong the Erlking or a demon might be, but they've got to work with physics just like anything else.

Right.  Got it.

But say you are a Hungry Ghost.  Your boss, Ebill Necromancer, has made it your goal in this particular bit of the afterlife to seek out Mr. Innocent Victim #3, who failed to yield the right-of-way yesterday and therefore must Suffer.  Unfortunately for you, that punk Wizard, Harry Dresden, got there first and put up a Magic Circle, inside which IV#3 is currently cowering.

This puts you in quite the predicament, because your entire purpose in existence at the moment is to kill IV#3, yet the annoying twit of a GM has just pointed out that a Hungry Ghost will melt into nothingness if it tries to cross a Magic Circle.  [Harry tags Magic Circle to trigger a GM compel on the high concept Hungry Ghost, or whatever variation of mechanics you choose to use to represent a magic circle].

Compels, of course, do not dictate an outcome, but limit your options or cause you difficulty in some way.  In this case, accepting the compel would mean that you accept that the Magic Circle thwarts at least your immediate attempt to eat IV#3, though it leaves a wealth of other options; some options might include raging and ranting and otherwise making your would-be victim soil himself, or eating the next door neighbor instead, or going home and crying.

But what would result from buying off the compel?  I would argue that if there is one option that is not available, it is "I spend a Fate point to ignore the compel, so the Magic Circle is no barrier to me eating IV#3".  Instead, it might be "I spend a Fate point to ignore the compel.  When I go back to Ebill, instead of blasting me to Kingdom Come (which might be a reward rather than a punishment), he forgets about IV#3 and pledges Bloody Vengeance on Harry Dresden instead.  He takes a ticket from the machine; it is number 378126."

Which is actually an example of accepting the magic-circle-induced compel, but buying off whatever compulsion Ebill laid of the ghost, instead.

Ok, I think I'm going to have to revise my thinking.  If a magic circle was merely a compel, then you should be able to buy off the compel as Tedronai states.  Which means it can't be 'merely' a compel.  So try this out for size:

Empower Magic Circle [-1]  The character adds the Empower Magical Circle trapping to their Lore skill.  This trapping allows the character to make a Lore declaration to change an existing scene aspect such as "Circle drawn in chalk" into a special scene aspect such as "Magic Circle drawn in chalk" -- and have it be true.  Assuming the Declaration is successful, the magic circle is treated as a threshold with a rating of half the character's Conviction (round up), with a minimum rating of 1.  Empowering a magic circle costs one point of mental stress.

So now there's still an aspect to play with, but there's also a threshold.  This would replace the whole sticky aspect "Violated a Circle" concept, since crossing the threshold already has mechanics for that.  Thoughts?  Balance issues?
Title: Re: Who can pop a Containment Circle?
Post by: Mr. Death on February 03, 2012, 07:10:07 PM
I'd suggest an alternative way to buy off the compel would be for circumstance to break the circle for you. Maybe IV#3 is too busy cowering to watch where he's stepping and accidentally breaks the circle himself.

Let me break it out.  We both agree that Demon Sorcerer can't cast an erase spell on the circle.  The point where there's some dispute on purely physical actions that are directed at the area bounded by the circle.

Specifically, physical actions on each side of the circle.

There are many ways to visualize the power limits of these Circles, but most germane to this discussion are the following:
a) a cylinder extending an arbitrary distance above the target, but with a floor at the level of the circle
b) a cylinder extending an arbitrary distance above the target, and a shorter but still arbitrary distance below the level of the circle

Now with option a, the creature just CAN'T affect the ground, because they are, essentially, standing in a contiguous force field: any force they are able to exert hits the circle wall/floor/ceiling, and is resisted per the rules. It would be up to narrative expedience whether the circle's field of effect would flatten the grass beneath it (assuming a soil-and-grass locale for the circle), but then again, eliminating irregularites like that that may be something the wizard is assumed to have done in preparing the circle.

With option b, there is some wiggle room. Additionally, it opens up the possibility of serious circle instability, regardless of the being contained therein. Any number of living creatures dwelling in the soil may "cross" and break the circle's effect if it extends any distance below the actual level of a circle crafted on soil and grass. This would be a very "gotcha" style of play. I can see a wealthy and magic-savvy criminal preparing a network of tubes in a particularly tactical bit of concrete floor, rigged with bullets or other physical projectile which shoot at the same time, so that if an enemy spellcaster manages to get a circle set up there, the defender can immediately take it down by shooting through the "underground" portion of it. But that's just one possible ramification of this option.

I'm not remembering any real "gotcha" moments from the text which would support option b, so I'm inclined to go towards option a, and ruling that any physical damage the trapped being could levy is functionally bound in an all-or-nothing force field that transfers no energy (other than sheer spiritual emanations) to the surrounding soil/concrete/Jello sculpture.

Now I haven't seen

I've always thought of it as a half-sphere, rather than a cylinder.  But I'd agree with option (a) for dealing with the 'bottom' of the half-sphere.

I'd suggest an alternative way to buy off the compel would be for circumstance to break the circle for you. Maybe IV#3 is too busy cowering to watch where he's stepping and accidentally breaks the circle himself.
But then you're dictating the actions of someone else.  If anything, *that* situation would be modeled by some variation of accepting the compel, then performing some sort of a social attack to taunt the victim into attacking you (thus breaking the circle) or fleeing (thus breaking the circle).  But making someone act stupidly merely by spending a Fate to cancel a compel against you makes little sense to me.

Well, the way I look at it, that kind of depends on if IV#3 is a PC or an NPC.

The Compel is that the Circle prevents the ghost from chowing down, as I'm understanding the example. Buying off the compel means that the circle isn't getting in the way of your objective, and the buyoff clearly cannot be "Well, I just ignore the circle," but can be some form of, "Something breaks the circle."

Okay, so maybe IV#3 accidentally breaking it doesn't fly, but maybe some freak occurrence happens where something else breaks the circle instead. A squirrel wanders in, is frightened by the ghost, and flees across the circle. My point was, one way to buy off a compel that a magic circle is in your way is to have circumstance remove the magic circle from the equation.

You need leverage to break Concrete like that with sheer pressure. You need something holding you down so that all of the force generated by your pushing is going into the concrete and not being absorbed by your own body. Strong the Erlking or a demon might be, but they've got to work with physics just like anything else.

Nonsense.  You've never swung a sledgehammer at the floor, have you?
Earlking's "hoofs" would be much akin to sledgehammers.

I have helped destroyed a 10'x10' concrete foundation, using a sledgehammer, and it required a lot of room to swing - a lot more than I imagine is in a containment circle.

LFMF: never swing a crowbar, even a huge one, at concrete - it transfers almost ALL of that kinetic energy to your hands and arms.

Yes. I've swung sledge hammers, mauls, regular hammers, hockey sticks, baseball bats, lacrosse sticks, shovels, and other similar tools. And do you know what they all have in common? They're all levers, and use leverage to do the work you normally could not do. What is the Erlking bracing himself on so that the force he's using goes into the ground and doesn't just make him jump/recoil?

If you tried stomping on concrete, your foot will give out long before the concrete does.

Specifically, physical actions on each side of the circle.

There are many ways to visualize the power limits of these Circles, but most germane to this discussion are the following:
a) a cylinder extending an arbitrary distance above the target, but with a floor at the level of the circle
b) a cylinder extending an arbitrary distance above the target, and a shorter but still arbitrary distance below the level of the circle

I think that's taking things a bit farther than the circles are described.  As gamers we look for limits on things so we can exploit them, but in the books a circle is a circle.

Here's how I see it working (based on the sources cited above):
1) If you can't force your way out of the circle via your mystic power (the way the Erlking almost did) then you can't leave the circle.
2) Flying over the circle, tunneling under it, smashing the material the circle is drawn on - that's leaving the circle and you can't do it (see 1 above).
3) Why? Because it's magic.

Okay - I'll expand on point 3.  The circle is a form of threshold, defining the world as "inside" and "outside".  It's not a normal threshold like the type you find on a house, but works metaphysically like a threshold.  When we try to define it further things start to breakdown and questions about burrowing, flying, etc matter, as does "is there plumping under the floor", "is the wiring in the ceiling breaking the circle", and a host of other issues.  Keeping things at "It forms a barrier because it's magic" fits with the way it's shown in the books and the feel of magic in the DV.

Going back to the books:
Toot-toot was imprisoned in a circle that had grass, pebbles, twigs etc in it - but he couldn't pick up a handful of grass and toss it at the circle.  Why? Because he couldn't break the circle.

Maybe if Harry ever does do that "what's a threshold? How is it made?" research we'll learn more, but I have a feeling that he'll be too busy to do it in the next book.

Leverage amplifies force.  Where you hold the sledgehammer determines how much of a mechanical advantage it gives you.

But if something is strong enough then doesn't need to amplify the force its strenght produces.  Think pile driver coming down and breaking a section of sidewalk - that's how I see someone with Might +10 or higher being able to stamp his foot.  When it comes to smashing things, Might +10 is just Great Might combined with Supernatural Strength - easily doable.

If it's just Great Might + Supernatural Strength, have fun with your instant bird's-eye-view of the neighbourhood.

A piledriver is attached to a big honkin' machine that's there to make sure that all, or at least the vast majority, of the force involved goes down into the ground instead of up into the machine itself. You can't say the same about someone's foot. Maybe, if they had the room to rear up and bring their foot down in an arc, but not really if they're just stomping straight down.

When it comes to strenght, Jim ignores some of the physics.  For example, he has strong but not tough beings picking up things whose weight should rip their bodies apart.  He has beings punching holes in metal or concrete - when their hands should break before (or with) the concrete.  A human sized creature punching a car shouldn't send the car flying (since it out masses him by so much) but that's how the books show strenght working.

By pile driver, I was thinking something along the lines of a pneumatic drop hammer, but maybe a hydraulic one would be a better example.  A hydraulic pile driver doesn't bounce into space when it is used, and without a creature's internal body being able to function a bit like that (internally braced against the force the creature's strenght produces) trying to punch a concrete wall would send the puncher (who masses less than the wall) flying back.
