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 20m long, 4m high, and 1.5m thick; or a circle that has a 6m diameter and is up to 6m high and 1.5m thick. The wall blocks line of sight.

When the wall appears, each creature within its area must make a

Dexterity saving throw, taking 7d8 Piercing damage.

A creature can move through the wall, albeit slowly and painfully. For every 1m a creature moves through the wall, it must spend 4m 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, taking 7d8 Slashing damage.

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.
