The narrow passage winds back and forth a bit before coming to a natural chamber. It is perhaps thirty feet wide and equally long, though irregular in shape. The ceiling is higher than the room is long. Everyone is overwhelmed by the pungent odor of bat guano, and it is easy to see several hundred bats clinging to the ceiling. Most of the bats are hanging motionless. A few are moving or stretching their wings.
While most of the bats are very tiny, there are at least half a dozen bats whose bodies nearly the size of a cat. Pyior's suspicions are confirmed - sawtooth bats.
Weapons in hand, the group tries to move quietly across the chamber to the continuation of the passage.
Sneak checks: Pyior 13+8=21; Ys-Baddaden 14-4=10; Danwyn 14+2-3=13; Ys-Korros 7+1-3=5; Aurial 7+10=17; rhodin 18-3=15.
The giant brothers do the party no favors in the stealthy arts. The jangling of their armor agitates a few of the bats, which in turn agitates the entire colony. It becomes a cloud of flapping and squeaking dark brown bodies. The giant bats join the fray and make threatening dives at the party while the smaller ones just fly around.
(Due to the circumstances, any attack on a giant bat has a 50% chance of hitting a smaller one instead. Assume that the exit is between 20 and 30 feet away for most of you.)
