Rix takes a shot from underneath the stairs, surprising one of the spiders, which squeals angrily as a bolt buries deep inside of it. Dartis takes out a dagger and makes some small progress cutting the strands, but it is not enough to free him. Kel scrambles away from the the spider swarm and gets closer to Alexander, walking slowly to avoid the webbing on the ground. He swings his blade at the spider Rix harmed, hurting it again.
In retaliation the spider fires another stream of webbing, sticking Kel to the stone slab behind him just as the first spider swarm flows over him, biting him with dozens of tiny fangs and unsuccessfully inflicting the priest with poison. The situation nauseates Kel, who can do nothing the next round but retch in disgust (Kel takes 1 point of damage and is unable to act next round).
The next spider attacks the stuck Alexander, biting deeply into his shoulder, and coursing poison into his veins. (-8 hps to Alexander, but no poison damage as I rolled a natural 20 for save). Instead of weakening the half-orc, it seems to strengthen him. With a warcry, Alexander rips out of the webbing around him, although his wild swing misses his opponent.
Rix is attacked by the second spider swarm, which swarms over the legs and waist of the kobold. The creatures bite into him, causing the rogue to yell in pain and surprise (-5 hit points, but no poison or nausea due to made saving throws).
Silas sees the predicament of his companions and lights the webbing around himself, Dartis, and Kel. It frees the trio, and burns away a portion of the swarm on Kel, but causes damage to the adventurers themselves (-2 hit points to Silas, Dartis, and Kel).
OOC: Kel, Alexander, and Rix all made their saves vs poison. Kel failed a nausea save, but Rix made his. Kel took a total of -3 hit points, 1 point from the swarm and 2 from the torch.
