Conjure Thorns

A tall wall of vines, thorns and roses grow in an area you choose within range, wilting away at the end of the spells duration. The wall can be a 20ft long and 5ft wide or cover a 10ft radius and is consider difficult terrain.. Creatures moving into or within the area, it takes 5(2d4) piercing damage for every 5 feet it travels. Perception checks made to see through the wall are made with disadvantage.

When you cast the spell creatures of size large or smaller in the area must succeed on a Dexterity saving throw or be restrained by thorny vines until the spell ends. A creature restrained by the wall can use its action to make a Strength check against your spell save DC to free itself.
