Killed as a newly 79 mage, w/ T1 Journey Merc and 79 earth pet. No buffs other than self, and merc buffs. Summoned 5 Gellid's, put 4 on ground. Pulled w/ Mala, gave pet aggro. Waited 10-15 seconds for aggro to build. Launched Host of Elements, Frenzied burnout, Swarm pet, casted Aegis on pet whenever it came up. Used Gellid and chain casted entire fight. Not once did Maligan cast anything. Pet stayed above 50% w/ merc on Balanced. I went OOM nuking + using swarm pet like crazy, but by that time, Maligan was dead. Merc was @ 70%. Dropped Mask of Dark Intent. Easy.
Same strategy used for The Claybeast and The Blight Wisp. Both easy fights, especially The Blight Wisp (seems to not have as many HP as the others)
