Cast when Damage Taken Support

Cast when Damage Taken is a trigger gem. It causes a linked spell to activate when the player accumulates damage taken.

The damage effectiveness increases with level, but so does the damage taken per cast; overall, the amount of damage that needs to be taken per damage effectiveness goes up at higher gem levels.

Cast when Damage Taken only "cast" spells. Attack gems such as Double Strike are not consider spells.
