So far so good in NG+. Can punch everything to death with this build. Chaos Caestus can be switched with Lightning when humanity is low. +15 Caestus can be switched for +15 Claws when slash/bleed is required (also improving PvP viability). For 100% PvE viability it's essential that you get the flippy ring (particularly to fight Titanite Demons). Great Fireball can be switched with whatever you need at the time. Keep Smough's, Giant's +5, and Steel +10 legs as alternates if you put on a mask or maggot.
