Hi quick question! If you use Arcanist Brand with a nova type spell like Ice Nova or Discharge, then does Arcanist Brand activate Ice Nova centered on the branded enemy, or on your character?
Like, can I assume that all Arcanist Brand activated spells activate on top of the enemy?
Arcanist Brand has a modifier that explicitly overrides where the triggered spells are considered to originate. This works very similar to Astral Projector, but is not limited to affecting Nova spells.
Note that this is only changing the location the spells are considered to originate from. That has no effect on spells doing things to the caster, only doing things at or from the caster's location.
So e.g. Triggering Blood Rage with the Brand will still add a buff to you, Flame Dash will still teleport you, Dark Pact will still sacrifice your life.
