Cannot be Stunned by Hits you Block 
Painforged is a notable Ascendancy passive skill for the Gladiator that grants additional chance to block if the player was recently damaged by a hit or grants increased damage if the player wasn't damaged by a hit recently. It also causes blocked hit to not apply any stun and doubles the damage of counterattacks.
