Ah! Enlightenment!

The calculation for spell damage defines how many Wounds the spell causes, not dice!

The scales have fallen from my eyes! Hallelujah! Thank you, brother, for guiding this unworthy one to the light!

Exactly.

Just as an aside, this made me recall a spell suggested by someone playing Menelaris at one of our quick booth battles at Gen Con. Krek's player was rolling badly and his arrows kept flying wide. Menelaris' player (who had already used magic to blow down a pillar on a Deep Horror -- and rolled well enough to still be standing) wanted to know if he could use his air-related magic to make sure Krek didn't miss by guiding the arrows to their target. That's the kind of creative magic and teamwork that got him a Style point -- though he never got to try it cause Krek's next arrow took out the Deep Horror sans magical enhancement.

Yep, had something like this happen back in March in the campaign game I was running. The player wanted to use his air magic to increase the range of the arrows another character was shooting. What kind of modifier to the DIF did you give the player for this? Using the Alter/Enchant Objects table at the time, I called it a +2 to the DIF.

Good or bad call?

+2 works well. How much more range did you allow?
