I'm really confused about armor. I've heard that gladiators armor raises your energy but I don't see it on the bonus list. If these armors do give bonuses could someone give me a link to a list of them? Ty
Gladiator armor used to raise your energy cap, but since Nightfall was released Anet changed it so all armors are the same insignia-wise when you buy them. You can increase your energy cap bye buying it separately from a Rune Trader and apply it to you chosen armor piece/s.
The confusion may come from the fact that the energy bonus insignia, called Radiant, are in the common tab rather than the Warrior tab at the Rune Trader.
shelms8, as a Warrior, you may wear insignia that are Warrior-only or common (as in, any profession can wear them.) Be sure to check both of those tabs at the Rune Trader.
