Trace Aura

You touch a small object no larger than what can fit in the palm of your hand and imbue it with a magical signature you can sense. For the duration of the spell, as long as the material component is on your person, you sense the direction to the object's location as long as it is on the same plane of existence. If the object is in motion, you know the direction of its movement.

The magical signature remains for the duration of the spell unless it is dispelled, the spell is cast again, or the signature is ended with an action.

The signature cannot be traced if the direct path between you and the enchanted object is blocked by any thickness of lead, even a thin sheet.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the duration is 10 days. When you cast this spell using a spell slot of 7th level or higher, the duration is 30 days. When you cast this spell using a spell slot of 9th level, the spell lasts until dispelled.
