So for the first time ever in almost 38 years of play, I have witnessed the first Death by Infravision (playing Labyrinth Lord, BTW).
The party -- human thief, human cleric, halfling, dwarf cleric, and elf -- burst into a room and found some goblins. They slaughter all but one, who ran down a stair screaming for backup.
The party starts to hear rumblings of many feet, howling and gibbering and thumping, and start to freak out; they are already down hit points, and not ready to deal with a whole swarm of goblins.
So they start pouring every flask of oil they have 15 feet down the stair, over the side of the short wall beside the stair.
They say they are going to wait until the goblins reach the oil, then hit it with fire. So far, so good...
Knowing the only fire they had at the time was the thief's lantern, I ask, "So what are you going to throw down there?"
"Oh," they say, "we'll use our flint and steel."
"Flint and steel? 15 feet down a stairwell?"
"Oh... um, somebody light a torch!" they scream, as I describe how the mass of goblins is now swarming up the stair...
I tell them they have a 2 in 6 chance of lighting a torch in time.
"No time!" shouts the thief, down to 2 hit points... who then throws his lantern down the stair, which shattered amongst the oil and the front rank of goblins.
The party shouts in joy as the first two ranks go up in flames! Then the fire dies down after two rounds... casting everything into darkness.
A few moments pass as both sides take stock, and the goblins once more start rushing up the stair. The elf and the dwarf, the only ones who can see, loose arrow and stone down the stair at the goblins, with the dwarf acting as a shield in front of the elf. The goblins can't hit, as both are heavily armored and swift...
And then the humans, desperate for light, fire up their other light sources, blinding the elf and the dwarf for 1d3 rounds!
Dwarf, unable to use shield and dexterity, becomes much easier to hit, immediately takes an arrow, dies, and falls down the stairs (and rolling into a goblin, killing the poor 1-hit point creature)... and so, Death By Infravision!
The previous session an elf got taken out with Death By Acid. The party encountered some new creatures -- I call them Screaming Mimis -- greenish balls the size of a beach ball with eyes on stalks and big feet that let them jump far and high. When killed by slicing or piercing weapons they explode, and anyone within 5 feet has to make a saving throw versus Breath Weapon or take 1d8 points of acid damage. The gnome's dog killed one with its terrible bite, and the elf failed her saving throw with a "Natural 1," and rolling maximum damage, melting off her face, and killing her...
At least they were able to bring her body out of the dungeon. When they fled the goblins they never got a chance to recover the dwarf's body... but I am sure they will encounter it again... mwahahaha!
