Round 6
"Where is it?!?! Not it, not it, not it..." Amearin frantically flips through his collection of scrolls, looking for a particular one... "Aha, got it! Hold on guys, backup is coming!" He takes a step towards Lydia and Frederick as he begins casting a spell.
Meanwhile, the summoned centipede's mandibles are suddenly lit from within by holy radiance, like a pale reflection of the lantern archon's silvery light. It lunges forward with supernatural ferocity, chomping at the worms before it.
Spoiler: Amearin & CentipedeAmearin will 5ft step to M/20 and then begin casting Summon Swarm from a scroll. He's going to try and summon a spider swarm on top of the worm swarm in F/19, assuming he's not interrupted.
Amearin HP 14/23
The celestial giant centipede will use its 1/day Smite Evil ability against the swarm in S/24. (It may still be ineffective, but this is the best its got!)
