Bat

Many varieties are included in the category of ordinary bats. They will attack only if cornered and forced into combat. Bat sonar allows flight in total darkness. In certain large caverns there could be as many as 1,000 or more bats.

Swarm. (minor) If startled, tiny common bats tend to become frightened and confused and will swarm around and fly into things, putting out torches, confusing spell casting, etc. (The DM will determine the exact effects based on the number of bats. Typically, a round or two taking 1d4 or at most 2d4 damage to all in the area as the bats relocate.)

Maneuverability. Anyone with a Dexterity of less than 13 who fires a missile at a flying giant bat does so at -3 to-hit probability.

Disease. 1% of victims bitten by giant bats contract rabies.

Giant Bat. The creature must land—usually on its victim—to attack with its bite. Some 10% of giant bats enjoy 1 hit (full) die (1d8 hit points) and do 1d4 damage with a bite. These creatures dwell in dark caverns, usually underground. In flight, they emit a high-pitched whistling sound, a navigational device which compensates for their poor eyesight.

Mobat

Neutral Man-sized Monster (12 to 16 ft. wingspan)

Surprise 20%; others 50%; Senses echolocation

Armor Class 2 (or AC 10 if not flying and AC 7 in restricted flying conditions)

Screech. (minor, 1 segment) Affects all in a 20-foot radius. All in the area must save vs. Poison or must spend 1d2 rounds clutching their ears in pain, effectively stunned (save for no effect).

The huge mobat is found only rarely, typically in warm climates where large caverns offer shelter and plentiful food. They are omnivorous but prefer warm-blooded prey which they attack with their fang-filled maws. These monsters have a dim, evil intelligence and a desire for shiny objects.
