Hellfire Ray

Feats

This exploit works as the flame arc exploit, but the arcanist needs to expend 2 points from her arcane reservoir instead of one. If she does so, half of the damage she deals is fire, and the other half results directly from unholy power that is not subject to fire resistance. Good creatures that take damage from a hellfire ray must succeed at a Will saving throw or be sickened for 1d4 rounds.
