@ErlenDuck, theres an set of "death" armour... like this: "mysterious ______________ of death" (the ____ are the name of the armour) if u equip one iten with this, you will make hits of 0-1000 and a 90% chance of critical!
the nice idea of killing a boss is: have high str, hit a boss with power attack,this will damage and push back the boss, he will heal/attack back to you, (normally they will hit the air) and move away, now charge, he will heal/make a charge/make something, this will make an streak of hits and finally kill the boss... dont work very well in ranged bosses
