Deep bat

Deep bats were a classification of bats that were native to the Underdark.

Despite their origins, they could be found on both the surface and below it. Although deep bats in general were rare to find, they were categorized into four main species, each exhibiting distinct behaviors and appearances.

Drow wizards often took deep bats as familiars.

The types of deep bats were:
 * Azmyth
 * Night hunter, also known as a dragazhar
 * Sinister
 * Werebat
