Creeping Vine

Special Trait Name. ROOTS: Where ever this creature originally grew from the ground will have a budding purple flower. Destroying this flower will halve the AC and HP of all vines that originated from this square.

On the ground: This creature is always considered prone for the purposes of attack rolls.

Action Name. GROW: The vine can grow into a nearby square, each square that the creature occupies has its own AC and HP.

ENTANGLE: When the vine grows into a square that is occupied by an enemy it entangles them. On the first turn of entanglement the enemy is rooted. On the second turn the vines advance and now grapple preventing all movement besides breaking the grapple (STR 15 SAV); when grapple is successfully broken the root reverts back to just rooting. If grapple escape was failed then on 3rd turn the vines advance further completely locking down the enemy and dealing 1d6 of damage per turn. While in the subdued state the entangled creature can make no actions, bonus actions, or reactions.
The Entangle can only be ended by destroying the vine that resides in this square. 

Unlimited Reactions round, can use each reaction once per each enemies turn.
