Here’s my strategy for this slippery character, located in Kun-Lai Summit:
This isn’t much use to anyone really, as I didn’t try to kill it using the pets… but here goes:
My strategy here, as with a couple of the other elites, was to survive long enough for Apocalypse to kill it off. I tried Nether Faerie Dragon and Life Exchange, but it didn’t work as well.
So, I used the Roach to cast Apocalypse then used the Whelpling and Lift Off to avoid Whirlpool wherever possible and heal up the other attacks. When dead, I swapped in the Skimmer for Soothe and Cleansing Rain. By the time they were both dead, Apocalypse had one round left and killed him good and proper.
