Soul Shatter (2 / 2): When soul ability is slotted. When your Health drops below 20% your soul explodes, dealing 2000 (ish) Magic Damage to enemies within 8 meters of you. This effect can occur once every 2 minutes.
The problem here is both the damage and the cooldown. 2 mins too low and damage too high. People are abusing this in blackrose prison. They die on purpose, making this proc then one guy resurrect everyone with sigil and the whole stage is cleared due to the sick amount of damage this does. Due to the low cooldown, they can do this tactic over and over again.
