Teleport Ward

You make an area within range magically secure. The area is a cube that can be as small as 5 feet to as large as 30 feet on each side. The spell lasts for the duration or until you use an action to dismiss it.

When you cast the spell, nothing can teleport into or out of the warded area. Planar travel is also blocked within the warded area.

Casting this spell on the same spot every day for a year makes this effect permanent.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can increase the size of the cube by 30 feet for each slot level beyond 3th. Thus you could protect a cube that can be up to 60 feet on one side by using a spell slot of 4th level.
