Alright, how's this. Might work if we have some luck with the dice. Venn (hasn't taken his turn yet) cast Crown of Madness on the cultist at P6, commanding him to attack (subdual) the dragonclaw, hopefully taking him out. Jeni go bear, move to O8-P9, and take out the cultist at P7 (assuming he didn't move). Carad moves the smoke illusion to the the squares N7-P9. Hunter and Jeni, being inside, would be hidden from the raiders, causing disadvantage to the kobold's slings. (Not sure how DM would rule on those in melee range though.) Next round, Hunter disengages, grab Morgan and the dragonclaw (if he's down) and retreats behind Jeni-bear. After that, we can decide whether to intimidate the rest to flee since we have their commander, or we flee through the back door and link up with the townsfolk.
If the crown of madness doesn't work, my suggestion is we do the same except Hunter just drags Morgan out of the frontline. Then we hope Jeni-bear can take out the commander.
