Also, Unkajo emotes to throw certain things at people that debuff you like rotten Tauntaun corpses or snow. When you see him preparing to throw snow at you, run clear of your groupmates. You will be encased in a block of ice which isn't attackable like the crystals in the Axkva Min instance. However, when a groupmate is announced to get hit with a rotten Tauntaun corpse, he needs to run to someone who is stuck in a block of ice, if any. If the thrown corpse lands on a groupmate in a block of ice, it'll make the ice melt and will release the prisoner.
