A really big city
A city plus suburbs or a mountain plus foothills
A big city plus suburbs
A major geographical feature
A very small country

A small country
An average country
A big-ish country
A genuinely big country

Use it when performing thaumaturgy that's intended to affect a large area. Spells generally start at "a single target" and move down up the chart at a cost of 2 complexity per step.
As explained in Your Story, wards and certain other spells have larger default sizes. At the GM's discretion such spells may be moved up the chart, reducing their complexity by 2 for each step.
This is the group chart:
1 person
2 people
4 people
8 people
16 people
32 people
64 people
128 people
2^8 people
2^9 people
2^10 people
and so on
Use it when performing thaumaturgy that's intended to affect a group of people through their blood or some other characteristic other than the area they're in. Spells generally start at "one person" and move down the chart at a cost of 2 complexity per step.
LARGE-SCALE EFFECT [-1]
Description: The effects you incite are big. Really big. Big enough to alter maps, at least local ones.
Musts: You must have the Incite Effect Power in order to purchase this one.
Note: You may purchase this Power multiple times.
Skills Affected: Any.
Effects:
Vast Effect. Given a moment of peace in which to gather your strength, you may use Incite Effect to place an Aspect on a large area. The maximum area you can affect is one building, plus two steps down the area chart for each time you've purchased this Power. If you have the Area Effect upgrade, you may make the creation of the Aspect destructive. The exact amount of damage suffered by any given person or object in the area is determined by the GM.
Big Attacks. If you have the Area Effect upgrade, you may target any number of additional zones with it by reducing your weapon rating by 1 per zone.
LARGE-SCALE ATTACK [-1]
Description: Your attacks cover vast areas. You could rack up a ridiculous body count, if you tried your hand at terrorism.
Musts: You must have the Area Weaponry upgrade for either Natural Weaponry or Enhanced Telekinesis in order to purchase this Power.
Skills Affected: Fists, Guns, Weapons, Discipline.
Effects:
Bigger Area. You may target any number of additional zones with your Area Weaponry upgrade by reducing your weapon rating by 1 per zone.
Mass Destruction [-1]. Given a moment of peace in which to gather your strength, you may make attacks that damage very large areas. You may purchase this upgrade multiple times; one purchase allows you to hit an entire building with one attack and each subsequent purchase moves your maximum attackable area two steps down the area chart. This is not the same as attacking everyone inside the affected area - if you hit an entire city with a powerful attack the city will be wrecked and many people will die, but some people will be randomly unharmed. The GM adjudicates.
LARGE-SCALE SPELLCASTING [-2]
Description: Your magic isn't necessarily stronger than that of others, but it's bigger. It affects more of the world.
Musts: You must have some form of spellcasting to take this Power. Miracles counts.
Note: You may purchase this Power multiple times.
Skills Affected: Conviction, Discipline, Lore.
Effects:
Big Evocation. With one purchase of this Power, you may cast zone-wide evocation attacks and blocks at no shift cost. With two or more, you may affect additional zones for 1 shift apiece and may affect everyone involved in a conflict (including yourself) for 2 shifts.
Big Thaumaturgy. For each purchase of this Power, you may move each ritual spell you cast one step down the area chart or the group chart for free.
Scion can crack continental plates with his laser beams. As such, he adds the Large-Scale Attack Power and 11 purchases of Mass Destruction to his Potent Selective Venomous Ranged Area Natural Weaponry.
Mab is a goddess, and her magic is naturally bigger than that of mortals. She has 3 purchases of Large-Scale Spellcasting, plus a Limitation attached to 15 more purchases to allow her to affect all of Winter with her spells without spending any shifts.
Shatterbird can break every piece of glass and computer equipment in an entire city by screaming. She has 6 purchases of Large-Scale Effect attached to her Incite Effect (Silicon Control) with a Limitation stating that she can only target an area if there's enough unbroken glass in it to transmit her scream.
Ebenezer wants to destroy a village. He thinks a 40-shift attack will do the trick, and adds 18 shifts onto that to move his spell 9 steps down the area chart. A 40-shift attack hits everything inside the village, killing the entire population instantly.
The Red Court wants to wipe out an entire bloodline. They expect to be facing powerful wards, so they make it a 100-shift attack. They then add 4 shifts to move 2 steps down the group chart so that they can affect up to 4 people - it's not a big bloodline. Later Dresden redirects the spell at the Red Court, aiming to take out roughly 100 000 vampires. This requires 17 steps down the group chart, so he subtracts 34 shifts from the spell and launches a 70-shift attack at every member of the Red Court.
Came up with this because I wanted to stat up gods, Scion, and Shatterbird. Figured I might as well make it a bit easier to represent things like Eb's satellite trick and the Changes uber-spell while I was at it.
As always, input would be greatly appreciated. The charts are basically made-up nonsense and I would really like a sanity check on them. And the Powers are occasionally handwavy.
Also, I'm not happy with the Power names. Any suggestions?
Cool.
I have to say that the Changes spell probably had way more complexity than this would suggest though. Wasn't it prepped by sacrificing dozens or hundreds of people -- which would imply a complexity in the thousands? With this, you could probably do it with about 45 complexity (7 to allow for an Epic defense + 4 + 20 for all consequences + 10 for a Mythic Toughness stress track + 3 for armor + 1 for takeout ).
That's not really a complaint about the rules though.
---
This really needs to be used with some kind of rules limiting stacking Declarations for unlimited complexity. Otherwise pretty much anybody with Thaumaturgy can blow up a continent just by taking enough time.

I think I might change the area chart a bit. In this version every 2 steps is (roughly....) x10 area. I added a lot of examples too.
