Club of the Forest Drake

As an action, you can strike the ground with this club causing thorns and vines to spout from the ground in a 20ft. square centered on you. Each creature in the area must succeed on a DC 13 Strength saving throw or take 1D6 slashing damage and be grappled by the plants for up to 1 minute. A grappled creature can use it's action to make a DC 13 Strength check, freeing itself on a success. At the end of each of it's turns, a grappled creature takes 1D6 piercing damage as the thorns constrict the creature.
