I got 14 free skill points, but that would only raise my unarmed to like 165%, from the 157 it is now.
My Mega Power Fist, targeted or untargeted, does 0 damage EVERY time. ZERO DAMAGE, critical or not. I can cripple his legs so he can only walk about 2 squares per turn, but eventually the turrets run out of ammo and there is nothing in the entire room that can hurt him (i have 5% Speech so I can't ask Sgt Rock's crew to help)
