Shade Stroke is a devastating area used exclusively by Evendim and only at level 5. The fast cooldown and massive damage will quickly destroy attackers. Shade Stroke only affects a portion of an arc in front of Evendim. Shade Stroke will do well over 1,000 damage to most characters without defensive buffs. The exact attack damage percent is not known.
One tactic to avoid the destructive power of Shade Stroke is to avoid being in the area of effect. The power is casted towards the player holding aggro. This is ideally a knight with strong defensive buffs. The remaining players may now stand behind Evendim and freely attack without taking damage from Shade Stroke. They will take damage from other areas which do not have such an arc limitation.
