The difficulty in the fight
Mortal online gold will no longer melee players. So if you get knocked into Keleseth or happen to move by him, he will not swipe in between his casts and kill a non-tank. The first Shadow Resonance should appear earlier in the fight, which will allow the Keleseth tank to have more orbs on him or her if Keleseth is empowered second instead of third. We did not want which Blood Prince was empowered second to be a major element of the difficulty in the fight.
