During the opener A7s boss would randomly aoe target 2 players u need to move out Asap. The aoes are huge and they pulse twice.

It is roughly 2casts into the opener and the aoes could spawn under u.

I'm applying hot shot without gauss barrel to save sometime, then gauss barrel on for the rest of the opener. Gives more time to have at least slug shot proc to move around in case u get the stupid aoes.
