I have been healing the Twintania encounter, and something about Dive Phase to Death Knight / Twister phase is confusing me. When our raid and tanks stand on the damage debuff areas during the transition, Twintania casts some large blue explosion, and about a second later everyone takes about 80% damage. Usually when this happens, I have her on focus so when she starts a cast and I run but most of the raid usually gets wiped immediately after that. I think all but me and the tank that moved are getting hit by a twister, but I'm not sure.
I think during the blue explosion she is doing her boss mechanic 1 shot move if the raid was bad. After the screen is no longer blue, we take the damage and then need to run immediately to avoid getting 1 shot by Twister or Plummet. Any idea what is going on? What is happening after the snakes are killed and she is transitioning?
Any help would be greatly appreciated.
