This unusual Ectosaur produces none of the faint luminescence common to the class, but so completely absorbs light over its entire surface that it has a two-dimensional, silhouette-like appearance, typically completely black but capable of flashing more intense colors as a threat display or camouflaging mechanism.
In addition to its shadowy appearance, the Gibbergeist can silently absorb soundwaves over its entire surface or "bounce" them in any direction it desires, further masking its location and confusing prey. When it does wish to be heard, the whispering gibberish of its namesake seems to echo from all directions in a maddening chorus of voices.
Gibbergeist slime is utterly transparent and quickly dries into whispy "cobwebs," invisible except for the dust and debris that may collect in the thin strands.
The largely nocturnal Gibbergeist enjoys stalking smaller prey over extended periods of time, taunting and terrorizing children, animals or weaker monsters for several nights in a row before closing in. While its semicorporeal properties allow it to hide anywhere, it is particularly attracted to small, dark spaces such as closets, behind furniture or from under staircases.
SHADOWFORM: the Gibbergeist is almost indistinguishable from a pitch black shadow.
SOUND MANIPULATION: the Gibbergeist can be dead silent or redirect sound as it pleases.
