Last weekend was a local game convention, Dragonflight #42. I signed up to run a pair of B/X-OSE games under the same general conceit that I run my Meetup games: I'll figure out what I'm running when I get there...
(Adventure spoilers, of course).
I had a pretty good idea that I was going to run 'Vats of Rats' on Saturday. The signed-up group included three of the usual suspects from our FLGS group, one of the player's daughters, and two new-to-me folks. The party was comprised of two dwarfs, two elves, a fighter, and a cleric. A sufficient group for sussing out the source of the mysterious man-rat who had appeared in town.
The party met the aforementioned man-rat in the reeve's gaol, and through some offerings of food and a blanket, were able to get sufficient information from the fellow, in addition to some random rumors around town.
They cautiously approached the 'abandoned' mage's compound, and were able to make contact with a pair of famished imprisoned man-rats in one of the exterior cells. Killing a monstrous rat that shared their cell, the party earned their trust and got some generalized information on the compound, and to look for the side door for entrance.
Safely accessing the compound, the party inspected the trap mechanism, which I decided to be comprised of a large Leyden jar, the size of a carboy. Of course they had to detach and steal it. So the party continued to stealthily explore the compound with a Leyden jar on a hand-truck with a really squeaky wheel.
The party soon found Natália Potkanová's quarters, telling her housekeeper rat he was free to go. They tossed the room, finding some good loot, before being set upon by a pair of man-rat guards. A brief fight, and the party was victorious.
Entering the dissection room, they got somewhat squidged out by the pieces-parts strewn about. They could smell the true lab, and prepared for assault. One of the dwarves pulled open the door, and the fighter hucked in the Leyden jar, hoping for some effect. Sure enough (die roll), it blew up. Natália dodged, but her assistant Vlastimil was one-shotted by the exploding apparatus. The party then burst in, firing bows and preventing Natália from casting spells. Seeing the party strength, I quantum-ogered in a few more man-rats to defend her, and the fight began in earnest.
