Round 282: Snitzky pops up at 85N5E and the swarm dodges the flames. (Rolled 26 Ref save) It takes 5 times 1.5 = 7 points of damage and has 15 hp left.
The swarm moves to 85N0E. Snitzky hits with an AoO for 1 point of damage. (Rolled 15)
The swarm pounds Snitzky for 9 and trips him. (Rolled 10 vs. 10, swarm has higher bonus)
Snitzky has 7 hp left, the swarm has 14 hp left. Snitzky is prone but not distracted. (Rolled 17 Fort save)
Great...I get it down to 7 and then get a monster that doesn't deal damage...rip-off.
A creature straight from a lunatic's nightmare floats out of the darkness and makes a beeline for the swarm, babbling and moaning to itself as it goes. Nutso the allip has a vaguely humanoid shape, but with shifting, barely discernible features that bristle with madness. Its lower half trails away into misty nothingness, and it leaves a faint trail of black fog behind as it moves. Nutso reaches the swarm and swipes a vaporous appendage at the tiny elementals.
