Is the red color the radius of the edge of the bombs, and not the center?
Ushu definitely needs to be moved, and maybe even given Haste. But so that they are not taken out together with Kamistella. I think we need to move him to the center and cast a spell so that he covers the rear units. Perhaps the Obsobs are already heading towards Ki.
Everyone except Kamistella is probably being skipped. Depending on the archers' turn, either Ushu needs acceleration, or an air shield on him, or healing.
Can the Obsob move before going into invisibility?
