Surama (esoterrace end boss) skill bug

Surama's skill "Collapsing Earth" should not hit and wipe the people affected when they jump and catch the air jets scattered around the room. Currently it does, regardless of whether the player(s) are on the ground or in the air.

 

yeah, me and a friend just tried it and he 1 shot us even when we glided in the windstream

 

Well,If u are well geared,then theres a way to deal with it.you n ur healer must not use any shield buff I mean the nice one.until he uses his collapsing earth.I usually kill it with my gladiator friend just the 2 of us.i use chanter and only used "divine curtain" when surama cast his skill.it spare us little HP left then we must immediately heal or use potion.and usually his "second" collapsing earth is the one that deals damage,after that just hurry kill him.n like u said,its useless to glide.good luck ^^
