if you like a fight, get infernal for sure, even with the good loot youll be going through armour so fast. The amount of times I had to call a buddy in to help me take one down is unreal. There is still 1 that I have not been able to beat, met him twice.....get near him...he throws me up, blinds me, throws a fireball at me while im in midair, then when i do find him (as im blind) hes got 1up and regen and takes a tiny bit of damage from an enchanted diamond sword....I will have my revenge....one day.
