Eldritch Seal

This spell inscribes a magical seal onto a surface that you can touch, spanning 10-feet in diameter. When a creature enters or touches the seal it is triggered, enveloping them in an entropic snare. The creature must succeed on a Strenght saving throw or take 1d8 force damage and become Restrained, or half as much damage on a successful one and avoid being Restrained.

The seal is only visible to you and creatures that have a Passive Perception of 14 or higher (creatures under the effect of Detect Magic are also aware of the location of the seal when within range.)

If in any circumstance where the chosen surface is broken, the seal is considered as Dispelled.
