Boil Blood
Comes with the usual disclaimers about Lucy's data, but it confirms the 25 modifier.
Apparently, so does our friend
Feign Death (I've fizzled 7 times in a row before) as well as shared priest
Healing line.
Only looked at a few spells, but it appears not every spell has a fizzle modifier (guess these are baseline) and I haven't seen a negative one yet.
Guess its a matter of 1. do p99 spell 'fizzle adj' match Lucy's stuff? and 2. should it? is that a classic parameter for spells?
