Wall of Thorns

Conjuration
Level: 6th-level
Casting Time: 1 action
Range: 120 feet
Duration: Up to 10 minutes
Components: V, S, M
Materials: A handful 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 60 feet long, 10 feet high, and 5 feet thick or a circle that has a 20-foot diameter and is up to 20 feet high and 5 feet 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 1 foot a creature moves through the wall, it must spend 4 feet 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.

B-Tier Wall of Thorns is a versatile control spell that excels at area denial and damage, but lacks the raw power or flexibility of top-tier 6th-level spells.

Player Guide

Position this wall to divide a battlefield and force enemies into difficult terrain, dealing 7d8 piercing damage to those who cross it—especially effective against melee-heavy enemy groups. Use the circular formation to create a protective perimeter around your party or trap enemies in a designated zone. The wall's durability (10 minutes, concentration) makes it reliable for extended encounters, but remember enemies can still move around it, so combine with other control spells to funnel foes into the thorns.

DM Tips

Clarify whether creatures can perceive the wall before moving into it—invisible walls can feel cheap, so telegraph their presence. Consider that the wall's 5-foot thickness allows passage around edges, so be prepared for creative pathfinding rather than absolute blockage.
