Barrier

You create a shimmering, transparent wall of solid magic on a solid surface within range. You can make the wall up to 10 feet long, 10 feet high, and half an inch thick, though it cannot occupy the same space as a creature or an object.

The barrier is an object made of magical energy that can be damaged and thus destroyed. The barrier has AC 10 and hit points equal to 1 + your spellcasting ability modifier. Reducing the barrier to 0 hit points destroys it.

This spell can create additional walls when you reach higher levels. You gain an additional wall at 5th level (2 walls), 11th level (3 walls) and 17th level (4 walls). If you create more than one wall with this spell, each wall must be connected.

Any wall created with this spell disappears when the spell ends.
