OOC: Dolgaunts are not particularly difficult to kill if you can get on all sides of one and hack away at it... as they do not wield weapons, they do not wear armor or any sort, and their attack involves grappling someone and then their tendrils burrow into the person's flesh and drain them of bodily fluids (CON drain in addition to normal damage). So they are not adept at fighting a group of opponents because grappling someone then makes them vulnerable.
However... you are not currently in a position to gang up on one, because the chamber is small enough that you'll only be able to fit a single person wielding a melee weapon into the room to attack it. And the opening into the chamber is so narrow that only one other person might be able to be outside to fire a ranged weapon into the room... and even they would be at a -8 to hit due to firing into melee and cover (unless of course it was Jango, as his wand of magic missiles only requires line of sight for an auto-hit).
