The first boss only even has 2 mechanics that matter. A knockback, and the order they explode in. The visual vomit doesn't change this fact. They always explode in the order the markers show up first. Everything you see before the insensible debuff is as it was.

Second boss though... creative but that boss suffers from chronic tanksolo. The entire party can be dead and tanks can just grab all of the remaining ones. Aside from the one that tethers them they deal no damage worth mentioning.
