Hades' normal staff attacks apply a Debuff to the enemy, called Blight. This Debuff stays on the target and can be refreshed. If an enemy is afflicted by Blight, each of Hades' other powers have an additional effect.
Ability #1 Death From Below
Hades descends into the ground and erupts from below at his ground location, doing damage to all enemies in the area. If the enemy is Blighted, they are also Slowed. Applies Blight.
Ability #2 Shroud of Darkness
Hades Silences all enemies in a cone in front of him. If the enemy is Blighted, they are also Feared. Applies Blight.
Ability #3 Devour Souls
Hades devours the souls of his enemies, dealing damage in a radius around him. If the enemy is Blighted, the enemy explodes dealing damage to nearby enemies and healing your allies. Enemy gods only take 50% of the damage from detonating Blights. Consumes Blight.
Ability #4 Pillar of Agony
Hades calls to all enemy souls nearby, pulling them closer to him over time, doing damage every .5s for 4s. If the enemy is Blighted, their Protections are reduced. Hades also gains Protections for the duration.
