R1T8: Lilim shoots a probing attack at the snakes, flinging forth her own ray of ice and cold for 5 cold, freezing a snake in place, and hurting another one or two that came in contact with that one.

End Round 1, Begin Round 2 ...

R2T17: The snakes, angered by the impact, move towards Gek'k. They are tiny enough (with no reach) that Gek'k is able to get a weak shot in for 4, enough to kill another snake. They swarm him and all of the various bites do 5, but Gek'k seems totally nonplussed by the fact there are so many and all around him. Perhaps this is because this is a common swamp encounter he's dealt with before. But with five bites there is another issue as Gek'k suddenly writhes in pain, losing 2 CON from poison!

R2T15: The Scribe judges angle and thrusts through a mass of the snakes for 15, and then does it again for another 15. Many snakes were skewered in this, with a snake or two barely squirming in their death throes on the points of his ranseur, and the swarm is noticeably diminished.

R2T14: Rezah, Gek'k is being swarmed. What do you do?

Gek'k on deck (note the change to CON and hps on your sheet), Teofilo in the hole ...
