The flail guy (let's call him Bill) was protected from the thrust by his armor. Bill then used the momentum from the shield bash to swing is flail faster into Carver's other side. The two archers fired already loaded bolts at Astaroph since he showed the highest threat, with no shield to block with and no good dodging skills he was struck in the lower left torso with one and another hit his shoulder. While the swordsman attempted to sneak off to fetch backup.

Edit: (Got ninja'd by Spoopy) Astaroph did not get hit with any arrows because the pouch of ammunition exploded and knocked the two archers off their feet
