Tracer-revealing spell

"STOP!" Spoiler warning! The following information is based on events in The Secret Society of Seven Sorcerers and contain spoilers.

The tracer-revealing spell (incantation unknown) is used to detect and reveal a tracer enchantment.

To use it, first the wizard or witch must pour a specific poweder on the ground around themself and some on themself, then the spell's incantation must be chanted that will change the tip of the caster's wand or staff to neon blue and then produce a bright thin golden chaiun, swirling around the caster. The chain, which is the tracer, can then be tapped with the wand or staff and the wizard or witch will then be able to teleport to the object's location, using the tracer as a conduit.
