A hard non-magical stone wall appears at a point you specify within the cast range. The stone wall is 6 inches thick and consists of ten square plates measuring 10 feet by 10 feet. Each plate must be connected to at least one other plate. In addition, you can also choose to form a stone wall with ten 10-foot×20-foot slabs, but the thickness is only 3 inches.
Wall of Stone 5e
Classes: Druid, Sorcerer, Wizard
Casting Time: 1 Action
Range: 120 feet
Components: V, S, M
Duration: Concentration, up to 10 minutes
If the stone wall is formed through the space occupied by a creature, the creature will be pushed to one side of the stone wall (you decide which side to push to). If the creature is about to be completely surrounded by a stone wall (or surrounded by a stone wall and another hard surface), it can make a Dexterity save. Those who succeed in saving throws will be able to perform a reaction to move at a normal speed to avoid being surrounded by walls.
You can shape the stone wall into any shape you want, but it cannot occupy the same space as other creatures or objects. The wall does not need to be perpendicular to the ground, nor does it require a foundation; but it must extend from a solid existing stone.
Therefore, you can use this spell to create a bridge across a canyon or build a slope. Suspended slabs need support when the span exceeds 20 feet, so the area of the slabs needs to be halved. You can roughly shape the stone walls to create structures such as sawtooths and battlements.
The wall is a stone object that can be broken by taking damage. The AC of each plate is 15, and each inch of stone wall has 30 health points. When the HP of a plate drops to 0, the plate is destroyed, and the connected plate may also collapse (according to the DM’s judgment).
If you keep your concentration on the spell for the entire duration of the spell, the stone wall will exist permanently and cannot be dispelled. If you fail to do so, the stone wall disappears when the spell ends.
