a skeletal bat like creature that wraps it's self in shadow with glowing red eyes, and is notorious for getting into unchecked rafters

magical malformity

technically the color of aged bone with glowing red eyes, but they wrap their bodies in a shadowy membrane causing them to have the appearance of shadows

looks like the vague shape of a bat, or black see through gauze placed over a bat

about ten inches in length from wing to wing and 4 inches in height, very light

glowing red eyes

a thin shadowy membrane and a bony structure underneath that

4" on average though larger specimens can exist

5oz

no vestigial features

not particularly aggressive but can appear to be if they decide to mess with one person in particular

swooping down and hitting things,

by being inedible to almost everything that does't eat bones

slightly faster than an average living bat

magically animated they are very difficult to kill

vulnerability to harsh light, it makes it so they can not fly

clacking and faint trilling

you can get bat bones, if very careful you could harvest it's shadow cloak but this requires advanced academical and magical knowledge and it is not considered a very useful substance

magical animation,

unlike regular bats Shadow bats have incredible eye sight and can even sense both the living and the undead near by

touch as they don't have any way of feeling anything

any dark place or places to hide from the sun

shadow bats do not feed in the traditional sense but do enjoy being near living creatures and pretending to eat

follow living things to annoy them other than that no actual migratory patterns

they hang around dead bats for a while and sometimes the skeleton will eventually rise as a shadow bat, other than that Wraith storms tend to cause them to spring from nothingness

they flock together in small groups of no more than ten

none

only things that eat bones

none

bats, ghosts, mischievous spirits

in Atlania they are considered ill omens, in stanzgar a pest
