Round 5
The archon grunts in assent at Barak's suggestion but has no time for further conversation.
Throwing the remains of its useless blade into the closest zombies face the archon lunges forward at the others nearby, teeth flashing.
Only when the celestial soldier is sure it has the zombies attention it moves past Barak and into the waiting air.
Standard action to aid Barak's acrobatics.
Aid Other: 1d20 + 9 ⇒ (5) + 9 = 14 vs DC 10
Move to Barak and jump off the roof staying in the square below to provide cover for his retreat. Note if for some reason he doesn't draw the AOOs then he stays on the roof where he is. Think he's smart enough to manage all of this.
Acrobatics (to avoid fall): 1d20 + 9 ⇒ (11) + 9 = 20
With any luck Barak can pull of a double move but he'll need a DC 15 acrobatics check to avoid falling prone with possible loss of brains....
