Vaal Blight is a Vaal skill gem that applies a debuff that deals chaos damage over time in a large area around the caster and greatly hindering enemies. The spell then expands to stack more damage.

Skill functions and interactions

• Each cast can land a maximum of 3 stacks on the enemy.

• Vaal blight and blight both count towards the maximum stack size of 20. Any stack size over 20 will not add damage.

• Vaal blight is not considered a channeling spell. It will not gain channeling specific bonuses to damage.
