Bronze tier for the treasure chest, I'm supposed to beat 15 sec of armor and perfect block. This is not an entry level challenge. Additionally, my only Armor break at this point is Egret Moto, which is a completely unusable move that only works if the AI decides not to react for several seconds while not blocking, moving, attacking, or being hit. Oh, and the AI kills me in 2 combos. =/ Maybe you got confused and thought this was a silver or gold tier challenge?
