Protect Threshold

2-level Abjuration

Casting Time: 1 action

Range/Area: Touch

Components: V, S, M

Materials: an ounce of salt for each foot of the warded portal’s perimeter

Tracing arcane sigils along its boundary, you can ward a doorway, window, or other portal from entry. For the duration, an invisible eldritch creature stalks the warded portal. Any creature that attempts to pass through the portal must make a Wisdom saving throw or take 4d6 psychic damage, or half as much on a successful save.

At higher levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
