Blight /6

A channelled, area of effect chaos spell that applies a debuff to enemies. Debuffed enemies take chaos damage over time as well as having reduced movement speed.

Name	Show Full Descriptions
Controlled Destruction Support	Grants more spell damage but reduces critical strike chance. However, Blight cannot critically hit meaning Controlled Destruction gives more spell damage with no drawbacks.
Efficacy Support	Increases the damage over time and spell damage of Blight. The increased skill effect duration also increases the duration of Blight's debuff on enemies.
Swift Affliction Support	Decreases the total duration of Blight's debuff effect but compensates for this by increasing damage over time dealt by Blight.
Increased Area of Effect Support	Increases the area of effect of Blight allowing it to affect a greater number of targets at once.
Void Manipulation Support	Grants more chaos damage but lowers the elemental damage of Blight. Blight only deals chaos damage so Void Manipulation gives more damage at no drawback.
More Duration Support	Increases the duration of Blight's slow effect and chaos damage over time debuff on enemies.
