Depends on Template. I could see the need to add Hit Fatigue being that 5th mod without considering Splintering. With Macing though the MORE dmg you do the more you drain the stam, so you want big hits for BIG spikes of stam loss. I cannot recall what the number is but your for sure walking at 1 stam maybe up to 3, which actually doesn't take long to regen, but your really just looking for that 1.25 second hiccup in their movement so that you can hit them again. I'm definitely trying out a warhammer and then I'll pick a nice 1 hander with crushing too. Maybe a club, though atm I cannot recall if a diamond mace has crushing still.
