@Grand Poobah Quake had taken 10 points of fire damage from the partially real fireballs.
Quake double moves, earning the ire of the shadow demons (14 points of damage)
Sunna full attacks the babau and makes ready to attack more
Denrag full attacks the babau
Sabrael starts casting another summon
Babau 2 and 4 both stand (take attacks of opportunity) and 5 foot step to engage Sunna.
Babau 3 and 5 take 5' steps to flank Denrag and make full attacks. None of them hit.
Babau 1 attacks the hound archon with a full attack and the archon looks mortally wounded, hanging on to life with just a sliver.
The three shadow demons invisibly pursue Quake. One sprints forward and pounces on him with disembodied teeth and claws, while the other two fall behind having used their sprint already.
The party has initiative!
