Warcamp of the Legion
The dead century has re-formed its ranks. Break the line, then break the Centurion — no one holds it alone.
A group raid opening at level 15, ending with Undying Centurion (level 18, melee). Its antechamber lies in Ruins of Pompeii.
Rewards
A clear rolls the boss drop table several times over and can yield a raid gem for a weapon socket. See Raids for the party requirements, the daily lockout and the falloff on repeat clears.
