Corrupted Shrubbery

False Appearance. While the shrub remains motionless, it is indistinguishable from a normal shrub.

Rake. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 2 (1d4) slashing damage.

Entanglement. The Corrupted Shrubbery extends itself towards another space within 5 ft. The Corrupted Shrubbery becomes part of the terrain for the duration, unable to attack. The entire space it occupies becomes difficult terrain. 

A creature in the area where Corrupted Shrubbery extends to must succeed on a Strength saving throw or be restrained by the entangling plants until the shrubbery dismisses its grip. (Save DC 11). A creature restrained by the plants can use its action to make a Strength check against DC 10. On a success, it frees itself.

As a bonus action, it can become mobile again when one of its occupied spaces is free, moving to that space. When it does so, the entanglement ceases to exist. It does not trigger opportunity attacks when moving back to its fighting form.
