all party member died. good experience till x12.
died by ice cage. 110k 1 hit. should've healed 1st instead of casting aura of restore.
anyway, from this vid, we can see some of critical serpentra skills:
ice claw: the one where ice trail follows
fly-ice breath: he flies and cast huge ice breath aoe. evade by going out of his flight path to the edge.
rotating breath: screen shakes, slow debuff. easy evasion by going nearer to him.
ice cage: animation debug still not fixed (ice on char) ~,~
but the serpentra animation before casting ice age is easily recognizable. he rises his head and flaps his wings. couldn't use my sacrifice coz still on cd >.<
black hole: he throws black hole in front of him and sucks players in. then he turns and tail coil wrapping to death.
