As it reveals a hungry, gnawing mouth full of piercing teeth, dozens more follow suit. \n'b' Creatures originally from deep within the elemental planes, ice borers resemble a shard of ice at first glance. They have thin, membranous wings that they keep wrapped tight to their bodies when not in flight, and their mouths look like cracks in the ice when closed. The icicle fa\xc3\xa7ade fades instantly if an ice borer has eaten recently, as its body gains a red tint from the consumed blood. \n'b'  Patient Hunters . Ice borers are carnivorous and station themselves above entrances to caves and on the eaves of buildings where icicles form. Hidden among the mundane icicles, a group of ice borers will wait for a hapless creature to walk beneath them, waiting to sense the warmth of a living creature. When a suitable victim approaches, they launch themselves from their perches to fall into their feast. If threatened by a particularly powerful foe or if their meal wasn\xe2\x80\x99t as easy as they thought, a swarm of ice borers takes wing to find a safer place to hunt.'
