yeah any attack indicator with arrows pointing inward means you need to take that attack to help split the damage. there’s a circle one where you need to be inside the circle, and a pillar one where you need to line up
there’s another indicator with arrows pointing outward which means you need to get far away, i forget if that one shows up there
if you get a red triangle (doritos) above your head, you need to stack with the other red triangles
you say you have the pillars down, but just in case i’ll mention that a lot of the time there are two pillars, and all pillars need someone inside them. noctis will arbitrarily run to one, and you need to watch him and run to the other one quickly
