Guy is an asshole, nuf said lmao
So i cant beat this guy, catually none of my 5 Glads seem to even come close!
Hell my level 2 War with Polearms beat the first 4 guys in the arena challenge in a row...

Any pointers? (My glads are still new, level 6 to 10)

Nightmare is a low activity Theatrics if I remember correctly. He will be difficult to beat with a 2 handed weapon until your gladiator becomes a bit more adept in his weapon skill. He's just difficult in general to all gladiators because he is strong defensively, and uses little stamina while your glad tires out while swinging at the air.
