Extra DPSer, huh? I absolutely could never have told that from your completely DPS-based character.
Okay, time to clear this up once and for all:
Power is the amount of force the spell has. The bigger the number, the more damage or damage-esque value the spell outputs. Average is around 100, but can be more or less.
Volatility is how likely the spell is to fail or miss. Recommended around 10-20, since 100 means 100% failure rate.
Difficulty is how hard it is to learn. Once this kicks off, a roll based on this will determine whether or not the spell is accepted on your particular character. Recommended to be around 15-20.
Oh, and the latest in the Dank Spells series would cost 3 WP to use normally, and 2 for Alex to use due to knowing two elements. 900 uses, woo~
Speaking of which, while I'm quite sure I know the answer, I want to make sure: what's everyone's preference on the result of hitting 0 HP?
