Gollux

You can still do the "get a few pixels behind Gollux to avoid his attacks" technique if you kill the abs instead of a shoulder, using Falling Sakura to heal if Haku's Gift and pots are on cooldown and you get caught by an attack. Managed to get through the entire hard mode jaw that way, only to be mercilessly slaughtered repeatedly by the flailing hands at the eye stage. Are the hands at the eye stage avoidable at all without straying into the 1hko cry zone? At the jaw stage it seems like you can just walk out of the way of any arm attacks if you're in the centre, but at the eyes stage the "safe" area is tiny and the hands always seem to go for it.

Also to add insult to injury, Shikigami Haunting can only reach the eyes if Gollux is facing you, if someone's attacking from the other side and Gollux faces them, Shikigami can't reach the eyes unless you stray into the 1hko cry zone. Not sure what to do at that point, find a way to the other side or Tengu them to death I guess.

Main issue is that my partner is a lumi. We need to kill a shoulder so he can just stay in one spot to cast reflect to kill both mobs. Once he casts reflect he's stuckin that animation, he can't jump cast.

Also we like to kill a shoulder because it makes so much easier at the eye stage.
