This is by far the worst co-op boss event I ever played.
If you die, you need to swin again to the plataform. You need to be careful to not engane the Oceanic original boss.
And a funny thing I would never imagine. I using Liza because she is great against the original Oceanic, can you guys believe this boss share his elemental reaction to everyone?
So, I using basic attacks with Liza and both the BOSS and everyone on my party are getting electro-charged. OMG. This is dumb by many levels. I actually killing other players.
