Mystic Mark

Regular 
Places an invisible mark on the subject. The mark is visible to the caster at will (simple concentration) and to others using Aura, See Secrets, Mage Sight, Detect Magic, or similar spells. It may be a rune, sigil, monogram, etc. (A Heraldry specialty may be learned to recognize the Mystic Marks in use in the campaign world.) Unwilling subjects resist with IQ. 
Should Seeker be cast regarding a subject bearing the caster’s Mystic Mark, there will be no need for “something associated with the subject sought.” 
The mark can be erased with Remove Curse.

Duration: Mystic Mark is a lasting spell that fades with time. Every month, roll against the Mystic Mark’s Endurance (p. 10). On an ordinary failure, the Mark’s Endurance is reduced by the margin of failure. On a critical failure or when the Mark’s Endurance reaches 0, the spell expires. Marks placed on durable objects are themselves more durable; apply the DR of the surface as a bonus to the “fading” roll. 
Cost: 3. 
Time to cast: 10 seconds. 
Prerequisites: Dye and Trace.
