Build Palisade

3-level Conjuration (ritual)

You conjure a wall of wooden posts on a solid surface within range. You create a line of these posts that create a wall going in a single direction that is up to 30 feet in length and 10 feet in height. At any size, the wall is 1 foot thick and lasts for the duration.
If the wall cuts through a creature’s space when it appears, the creature within its area is pushed to one side of the wall and must make a Dexterity saving throw. On a failed save, the creature takes 3d6 bludgeoning damage, or half as much on a successful save.
The wall is an object that can be damaged and breached. It was AC 12 and 30 hit points per 10-foot section, and it is vulnerable to fire damage. Reducing a 10-foot section of wall to 0 hit points destroys it. The destroyed section is treated as if it were difficult terrain for the duration of the spell.
