Hey there, wanted to let you know you have this spell loaded in incorrectly for the last boss. Logs as avoidable for party, it isn't.

Unfortunately, the two parts of Colossal Blow (frontal with stun / party dmg) share the same spellID and cannot be separated. I opted initially to include it as avoidable, but as classes can mitigate the AoE more or less effective, this skews the overall results of the dungeon heavily.

I have moved Colossal Blow from Avoidable Damage to Avoidable Auras for #53 => This should hopefully only track the stun portion (and thus the avoidable frontal).
