So, I tried with defiler, but no luck. The Frozen terror attacks the pet, but when it's time for him to cast his Ice Prison he casts it on me. Same goes for the Druid's tanking pet. And the Druid's healing fairy stops in her tracks as soon I'm in the ice prison.
Are you guys sure this is soloable?
The person who gets frozen is the one without agro generally when it comes to mechanics like that, on the other hand i can't even remember that boss anymore he should at this point be dying before even trying to activate his icicle anyway
Otherwise you'll just have to use a dps pet and have it finish the boss for you or dps you out of the crystal
