Most prey ignores the ground they walk on as they anxiously eye every chest, doorway, and window around them. The rug mimic evolved to take advantage of this. A long, flat creature most of the time, this aberration delights in creating complex patterns in its false weave. It will even let potential meals walk all over it, sometimes back and forth for days before striking. One odd quirk, however, about this mimic breed is they are easily riled when someone wipes their feet off on them. More often this will cause them to strike, even at inopportune moments.

Adhesive (Object Form Only).

The mimic adheres to anything that touches it. A Large or smaller creature adhered to the mimic is also grappled by it (escape DC 14). Ability checks made to escape this grapple have disadvantage.

False Appearance.

While the mimic remains motionless, it is indistinguishable from a large, fine rug.

Grappler.

The mimic has advantage on attack rolls against any creature grappled by it.
