You place an invisible mark (a glyph, rune, sigil, signature, magic circle, etc.) on a creature or object that you touch, allowing you to determine the general direction of your mark so long as it is on the same plane of existence. If the mark is within 30 ft. of you, then you can clearly determine the mark's location and can dismiss it at will. If the mark is forcefully dispelled or destroyed, then you take 1d4 - 1 psychic damage.

The effect of the spell immediately ends if the creature dies or the object is destroyed, if the mark is slashed or torn, or if the mark is on a different plane of existence. If you have more than one mark active at a time, then you cannot determine the direction of either mark, and you cannot distinguish between them upon being alerted to a mark's destruction. 

If your mark is discovered through magical means, then divination spells such as identify can be used to determine your identity and general direction. 

An unwilling creature must succeed on a wisdom saving throw to resist being marked by this spell.
