Eye for an eye

[Sinaloa]

Since you hear more often how bad this skill is followed by a completly wrong explaination here´s the tooltip:

Erects a magicked barrier around a single party member or pet for 30s.
Barrier Effect: 20% chance that when barrier is struck, the striker will deal 10% less damage for 20s.


This does not mean that an average of one in five hits deal 10% less damage.

Every hit got a chance (of 20%) to debuff the enemy upon a sucessful hit. The barrier lasts 30 seconds. The chance the debuff applies is sth between 90 and 97% on average depending on the enemies attackspeed. Multiple enemies each have a chance to be debuffed for each blow they land.

As an enemy is debuffed it will deal 10% less damage. It´s not relevant whom they deal the damage to.
e.g. The tank was buffed with Eye for an Eye. Titan hits the tank several times and finally gets debuffed. Every move he does including his stomps 10% less damage for 20 seconds.

The barrier lasts 30 seconds and the debuff 20 seconds. This means it can happen that a mob can be debuffed 40 seconds from one barrier if you are lucky.

Granted it isn´t that good on tank and spank enemies ist awesome on large addpulls like wp and unavoidable aoe encounters like Titan and Coil.
