Jerek cannot move completely away from the rat without risking being injured by it, but he can take a quick, careful step at an angle that would give him a clear shot at the bugbear, and this he does, his arrow striking deeply into the bugbear's shoulder. Jair continues climbing down, but his greater speed causes him to miss a grip, and he wastes more precious moments finding purchase again. Heirmund turns and fires a small orb of acid at the bugbear, then moves to the only cover in the room--by positioning himself so that the melee is between him and the bugbear.
((Jerek's attack: 18+3+1=22. Damage: 3+1=4. Jair's rapid climb checks: 17-3=14 and 7-3=4. Heirmund's touch attack: 18+2=20. Damage: 2.))
The rat presses its attack on Jerek, stepping forward and ripping into him with its dagger-like teeth. The wounds finally catch up with him, and Jerek drops his bow, staggers to his knees, and falls unconscious. The bugbear then moves around Terrek as well, drawing another javelin as he does so and casting it at Heirmund. In an almost exact repetition of Lehko's fall, Heirmund too feels it rip into his side--and then is consumed by darkness.
((Rat's attack: 21. Damage: 2. Bugbear's attack: 14. Damage: 4.))
The vines seem to be working against Jair, and as he scrambles from yet another slip, he realizes from the noises that only Terrek remains. And then his loyal companion gives a terrible yelp--and utter silence descends upon the chamber. He continues climbing, not having any other choice, but knowing he is already too late, far too late. He looks down into the room to see the bugbear calmly approaching to stand underneath him, the single remaining dire rat following like Jair's own faithful hound--who now lies bleeding with the rest of his dying companions.
((Terrek's attack: 7+3=10. Jair's climb checks: 4-3=1 and 16-3=13. Rat's attack: 18. Bugbear's attack: 21. Damage: 11. Jair's final climb check: 16-3=13.))
The world seems to pause for a moment as the two foes gaze at each other; one clinging with one hand to vines in a hole in the ceiling, the other bloodied and standing in the muck below. Then the moment is broken as the bugbear pulls back his arm to cast the javelin. Jair draws his spear, and even as the javelin rises to meet him, he launches off the vines, the spear clasped two-handed as he plummets down to the creatures that brought such ruin.
