Dimensional Lock (Remnant)

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 120 feet on each side. Creatures cannot teleport into, out of or within the warded area, nor can Ethereal or Astral beings materialize within. Similarly, creatures cannot be summoned within the warded area and any and all forms of planar travel are blocked within it as well.

A creature that attempts any of these actions within the warded area takes 8d4 Force damage, or half on a successful Charisma save. The area of this spell is invisible and very subtle, creatures must succeed on an Arcana check against your spell DC to realise it’s in place.
