DFRPG / Re: Using Thaumaturgy for Evocation-like effects in Combat
« on: May 25, 2011, 04:39:00 PM »
One of the characters in my game is an exorcist, having only Ritual (Diabolism) in terms of magic. I let him do Thaumaturgy in combat, based on the conceit that anything at or under his Lore he has the stuff for, and anything above he has to pull in somehow to meet the Lore deficit (and that this FUNCTIONALLY makes Thaumaturgy unusable in combat, but not EXPLICITLY making it unusable in combat).
His Lore is +5, so he can perform a 5-shift ritual by forming the magic construct on Exchange 1, and attempting to power it on Exchange 2 - n. This is likely to get you little.
He's used it to make a quick-and-dirty 5-shift Ward before ... being a Diabolist it is only effective against demons. Exchange 1: "I'll make a ward! I grab my chalk and put down a circle." Exchange 2: "I need to get this circle up, I'll haul down all 5 shifts of power." ... but with a Conviction of 4 and a Discipline of 4 he has to take a point of stress and make a +1 roll for Discipline.
Now, outside of the norm, I've allowed him to make attacks with Thaumaturgy. Not Evocation-style attacks, but we based it off scaling WAY back on the "Lasting Change In A Target" method of "winning a conflict in one roll" ... by turning that back into "winning a conflict with a bunch of rolls". I.E. - Turning Lore into a slow, dangerous, cumbersome attack skill.
Since it only works on demons, we characterize it as starting and continuing an exorcism in combat. He has the sympathetic link (his exorcism tools) and can frame the ritual (Exorcise The Demons!) in Exchange 1 and fuel in Exchange 2. That being cumbersome the player asked if he could take the standard two-actions-at-once penalty and do both in one exchange at a -1 to both. It works for our game, so I let it go. Essentially allowing him to make a 4-shift Weapon:0 attack.
In Evocation, the power of the spell (Conviction) sets the Weapon:X level while the control (Discipline) is the targeting roll. Since we were basing off the permanent change, the complexity of the spell (Discipline) sets the flat un-rolled attack value and the control (Discipline) merely determines backlash, fallout, or success.
So where he might have a ritual of Complexity 29 to ... target the Demon's Presence, account for a +4 roll, account for 2/4/6/8 consequences, etc etc ... it's just a flat "Difficulty 4 roll against Presence".
He's tagged Aspects to up the ante, but it means this methodology is expensive either in FP or stress (sucking down Conviction-topped mental stress or Discipline-topped backlash). Unlike Evocation, where uncontrolled power can be selectively spilled as Fallout or swallowed with Backlash, the Thaumaturgic nature means it all has to come back as Backlash or the whole thing is wasted.
Compared to Evocation, it's slow, dangerous, and pretty weak. He has an enchanted item that pops out a Weapon:6 Spirit attack vs. demons only (Banishing Mirror) and that's far more reliable for putting combat hurt down. The Weapon:X values on evocations make them insane combat weapons with only minor min/maxing, so even leveraging my "eh, I'll allow it" to the hilt the guy with the Weapon:2 handgun is far more effective for standard attacks. It's only by bypassing the usual "mook" monster physical tree and using the thaumaturgy to target their mental tree that the laborious methodology even seems attractive.
