Ability Description

You harmlessly place your unique magical sigil, which is about 1 square inch in size, on the targeted creature or object. The mark can be visible or invisible, and you can change it from one state to another by recasting the spell on the object or creature touched. The mark can be scrubbed or scraped off with 5 minutes of work. If it's on a creature, it fades naturally over the course of a week↗.
The Sigil's ability to hide, mislead, and/or distract can be used in combat. Roll a corresponding skill check (Stealth, Deception, etc). An enemy who is fooled by or affected by the the sigil is considered Off-Guard until they are struck.
