Eye of Vengeance (Level 20)
This smoldering black orb replaces one of your eyes. As black veins stretch across your skull, the urge to avenge wrongs inflicted upon you is nearly overwhelming.
Item Slot: Head ............... 125,000 gp
Property: You cannot be blinded.
Power (Encounter): Immediate Reaction. Use this power when you are hit by an attack, even if the attack reduces you to 0 hit points. Make an attack against the enemy that attacked you. (Your attack may target additional creatures as well.) You gain a +2 bonus on the attack roll against the enemy that attacked you, and if this enemy is hit by your attack, you can spend a healing surge to automatically treat the result as a critical hit.
