Vine

Summon a 15ft long vine somewhere in a 30ft radius that the caster can control at will. The vine lasts for 4 turns or until it is killed. The vine is very flammable.

Each additional level for the caster past level 2 gives the vine 4 additional hit points, starting at 10 for level 2.

Wrapping the vine around an enemy will deal 4d6 of bludgeoning damage per turn that increases by 2d6 every 2 caster levels starting at level 2 as well as restricting the enemy so they cannot cast spells requiring a somatic component. 

The vine can also be jabbed at the enemy, dealing 5d4 of natural damage which increases by 2d4 every 2 caster levels starting at level 2.

The vine can be used to sweep the ground, dealing 3d6 of bludgeoning damage per turn which increases by 2d6 every 2 caster levels starting at level 2 to every enemy hit.
