PVP SUPP Priest build: 60 rubies.
60 rubies is far below what you should have tho, ur minimal rubies should be 68, CS exclusive.
For stats I'd recommend 300 Double attack, 1 deter, 40% prof/60% brutality of what's left of your stats.
For defensive I'd recommend 400 caution, 250 survivability and all else into vitality. Perhaps dmg types protections up to 250, but that'd be only for 3x3's and small scale pvp.
