Skill functions and interactions

Doom Blast is considered a spell, therefore modifiers to spell damage apply to it.

Doom Blast is triggered when a hex ends, and its damage benefits from bonuses of the ending hex. E.g. the reduced chaos resistance from Despair.

Due to animation timing differences between classes, some classes like rangers require slightly more cast speed than classes like witches when using a curse with Impending Doom and a different curse with Spell Cascade SupportSpell Cascade SupportAoE, Spell, Support
