Wall of Thorns

You create a wall of tough, pliable, tangled brush bristling with needle-sharp thorns.

The wall appears within range on a solid surface and lasts for the duration. You choose to make the wall up to 60ft long, 10ft high, and 5ft thick or a circle that has a 20ft diameter and is up to 20ft high and 5ft thick. The wall blocks line of sight.

When the wall appears, each creature within its area must make a Dexterity saving throw. On a failed save, a creature takes 7d8 piercing damage, or half as much damage on a successful save.

A creature can move through the wall, albeit slowly and painfully. For every 1ft a creature moves through the wall, it must spend 4ft of movement. Furthermore, the first time a creature enters the wall on a turn or ends its turn there, the creature must make a Dexterity saving throw. It takes 7d8 slashing damage on a failed save, or half as much damage on a successful one.

At Higher Levels

When you cast this spell using a spell slot of 7th level or higher, both types of damage increase by 1d8 for each slot level above 6th.
