2 — Giant Rats

GIANT RATS (amidst garbage and waste): There are 18 giant rats [statistics 1]. Each time a character is bitten there is a 1-in-20 chance of getting a disease, unless a save vs. Poison is made. If the saving throw failed, there is a 25% chance the character will die in 1-6 (1d6) days. Otherwise the character will be too sick to adventure for one game month. These monsters are the pets of the kobolds, living off the garbage and waste of their hosts. They will rush to the sound of the trap door closing or of battle. They have nothing of value in their lair or on their bodies, but their leader (rat #18) who will be at the back of the pack, a huge fellow [statistics 2] wears a thin silver chain set with 5 small gems (jewelry value 400 gold pieces, chain value 50 gold pieces, each gem worth 50 gold pieces). The weight of a few rats will not trigger the pit trap.
