And now for something a bit more serious, Nightmare!
Stats:
Human Theatrics Gladiator
84 Strength
63 Intellect
66 Agility
77 Stamina
87 Size
78 Presence
56 Chi
He's level 9 and has 502 Health and 77 Endurance
Gear:
His gear is a bit odd, he wears a white Medium Armor Chest, an epic Light Armor head, a blue Light Armor Weapon Arm, white Light Armor Shield Arm and white legs.
He wields a single, blue, one handed axe.
Fighting Style:
He's a very defensive fighter, most likely set to Parry-Bash. Strikes hard, but not often, however, he's hard to hit as he kinda spams Create Distance.
Beating him:
Personally, I find this guy to be a very tough nut to crack for many of my gladiators. I've had the best results trying to hit his back leg or shield arm, as those have the lowest armor.
While Two-Handed war and rage gladiators have a slightly easier time, fast attacking rage or theatrics will definitely have issues with Nightmare. Another option would be to try and wear him down
with a defensive gladiator, since his Endurance isn't gigantic.
Edit: Updated with the new changes. This guy hasn't changed much, he remains the same pain in the butthole.
