Walls of Redoubt

5th-level transmutation

Casting Time: 1 minute

Range: Touch

Components: V, S

Duration: 10 minutes

You inscribe potent sigils on a section of wall up to 30 square feet, be it wooden or stone. The wall affected by the spell takes on a semblance of animation, able to twist, bend, and shake of its own volition. While it is not intelligent, it responds to you and your allies favorably, and to your enemies unfavorably. The wall gains the following characteristics:

• Any enemy attempting to climb or break through the wall, or any portal in it, suffers disadvantage on relevant ability checks. You and your allies gain advantage.
• The wall doesn’t provide cover for your enemies.
• The wall gains resistance to damage from attacks by your enemies.
• You don’t need to spend an action to open or shut any portal, window, opening, door, or gate within the wall. You can freely cause any such portal to open or shut on your turn. You don’t have to be adjacent to the portal; it opens or closes magically.
• You can cause any portal along the wall that has a lock to lock or unlock on your turn, without using an action. You don’t have to be adjacent to the portal; it locks or unlocks magically.
• Enemies that move to a spot adjacent to the wall or start their turn there suffer 2d6 bludgeoning damage as the wall buckles and attempts to batter and crush them. A successful Dexterity saving throw halves the damage.
• All terrain adjacent to the affected section of wall, to a distance of 30 feet, counts as difficult terrain for your foes. Pre-existing difficult terrain in that same area doesn’t hinder you. This doesn’t affect other magic that alters terrain, such as an entangle spell.

You must remain within 300 feet of the enchanted area for the spell to continue to function.
