Boss and tags
Boss (from Maps of Exile): Same as Act 1 fight. First phase avoid Merveil's cold spells. Second phase can be hectic. Watch out for the Heir of Flame and Storm when they arrive. Stay out of geysers which do large amounts of Cold damage.
Way to the boss: Boss either up from spawn or up and to the left
