You always thought being the party rogue was an easy gig. Sure, when fights erupted things could get hairy but most of the time you focused on unlocking doors and working on simple traps. What could be more simple than a hidden snare? It was almost embarrassing when you ran across a few on the floor. Getting rid of them should have been child's play, but your tools and hands got stuck to one just in front of the next door. Then it wrapped around your arm like a living thing, and now it's pulling you toward a hole... no a mouth in the wall! Roll of initiative.

This mimic breed came into being because the first such monstrosity saw a roper and thought, I can do that and do it better. It took some work, but eventually, the mimic settled on becoming a wall section and extending pseudopods to wait. This meant weakening its overall tentacles, but the passive trap worked as expected. To compensate for the lost strength, the mimic evolved a more powerful bite than its peers. Its last adjustment was ensuring its snares could detach as needed, much like a lizard's tail. That way it can deal with one meal at a time.

Snares.

The mimic has three Snaring Pseudopods it can extend up to 15ft away from itself that appear like ordinary hidden snares (DC 13 to detect) until the mimic makes an attack. A creature restrained by one of these snares can attack the mimic as if they were within 5ft, but with disadvantage. The mimic can use a bonus action to detach a Snaring Pseudopod to keep a creature grappled (Still DC 14) were it is at and that creature loses the previous effect. The mimic reproduces all detached Snaring Pseudopods after a long rest.
