Chuck Norris also has unique IO enhancements, like Roundhouse Kick, Intimidating Stare, and Beard Fist. Each enhancement in the sets acts as every type of enhancement all at once, so the Roundhouse Kick set is effectively 6 Acc, 6 Dmg, 6 Def, 6 Resist, 6 Heal, etc. and they all grant pre-ED levels, so you don't have to worry about 6 slotted powers. Each set is Unique, but Chuck Norris can slot them in every power, ignoring the one of each limit on unique enhancements, and the set bonuses stack beyond the normal limit of 5 of a given type. What are the set bonuses? They are insane, that's what. Everyone is a proc the proc rate is at will.
