Track

You place a magical sensor upon a weapon of your choice. It could be an arrow, a shortsword, or an improvised weapon, such as a large stick or rock. The next target that is hit with an attack by that weapon must make a wisdom saving throw, or become imbued with the tracker's energy. On a failed saving throw, the caster knows the targets location for the next 8 hours as long as they are on the same plane of existence. This spell was specifically made to pierce the normal barriers one might put up to protect themselves from scrying. Therefore, nothing short of a Greater Restoration spell can remove this effect. On a successful save, the creature is not subjected to the effects of the spell.
