Some rustling and squeaking will betray
the presence of a hungry horde of giant rats.
Any bite may inflict disease; the chance is
5% (check per hit). These rodents live on
the shelves along the walls, and some lurk
around the staircase. They are hungry and
attack without fear. Though they have no
treasure, an overlooked jug of oil (10 flasks'
worth) is on the upper shelf of the storage
area, and on the fifth stair down is a gold
ring worth 40 gp. However, if the party does
not SEARCH, the ring will probably pass
unnoticed. Roll 1d20 per person using the
stairs; the ring is discovered on a roll of 1.
