Ashen Mark

You conjure a faint, ashen glyph on a surface or object within range, visible only to you and up to three creatures you designate. The glyph can be a simple symbol, word, or image no larger than 1 foot in diameter. You can use a bonus action to cause the glyph to emit a soft pulse, alerting designated creatures within 60 feet of its location (no line of sight required). The glyph can be dismissed as a bonus action. Scaling: The number of designated creatures increases to six at 11th level.
