Old School Friends continue our D&D Dungeon Hack

Damn it, is it not a frustrating blast when those darn adventurers get their act together and bamboozle a clump of dangerous looking monsters (in this case a band of five Bugbears). By deft and cunning use of a magician's familiar, a Dragon Breath spell (see cotton wool below in the picture below) which as it came from a completely unexpected direction, "spooked" the monsters into stampeding into a well set up trap, aka killing zone (see below, as their "singed" [Bugbear] leader fell along side another Bugbear to the deft back-stabbing of the party's two thieves [the tiny Gnome thief dropping down from a point above the archway - a set-up that is becoming his trademark move], the "force morale" of the remaining three Bugbears crumbled [as per the three Bugbears exiting south at the bottom of the photograph]): 

Catching but a short breath the adventurers then moved onto the "next room" and came across another three Bugbears plus their Drow overseer. Two of the Bugbears and the Drow were distracted as they searching in a chasm for "something" (see the figures in the white 'chasm floor' area [top part] in the photograph below). Silence whispers and mutterings  - the PCs were up to something. Sure enough they had a "plan" very similar to their last escapade. However, the party's next assassination plan (meticulously worked out beforehand) came unstuck right at the start of its execution. The magician's familiar was this time spotted and "plucked" from the sky [by exactly "what" the party are not sure of], but at least the party's thieving duo still managed to take out the isolated Bugbear on guard duty up top, already dead as he toppled to the chasm below (see below, the party's killing spree continues, but now the enemy now know they are there):  

I am looking forward to the resolution to this Mexican stand-off in the next session.
