Roper

Ropers are monstrosities, they are ambush hunters, taking the appearance of a stalagmite while waiting for their prey to get close.

Appearance
While waiting for prey they were indistinguishable from a regular stalagmite. When in combat they would reveal their tendrils and their fang-filled mouth.

Known Ropers
Mighty Nein encountered two ropers while making their way through the Underdark tunnels left by the Kryn drow. They also encountered a roper on the bridge on their way through the Umbra Gates.
