Hallok teleports 80 feet into the air with a quickened dimension door. He then hits the hechatonchieres with a quickened banishment spell (will DC 49) and then casts time stop. With his arcane spells urge still active, he's able to cast five maximized sonic delayed blast fireballs at the atropals (Reflex half DC 50/each, 90 damage each) and five spheres of ultimate destruction, three of them maximized via his rod. He sends one regular and one maximized sphere as well as his black blade toward the atropals, and sends his two maximized and one regular sphere at the phaeton.

The atropals need to make three fortitude saves (DC 50) each, two of the spells doing 240 damage, and one doing (40d6)[147] damage.

The phaeton has to do exactly the same thing. Roll for third sphere: (40d6)[133]

I am really burning through my ninth-levels.
