Tracker

You touch a focus and create a small rune on that focus. You sense the direction to the focus' location, as long as that object is on the same plane as you. If the focus is in motion, you know the direction of its movement and speed. If the focus travels to another plane you know which plane, but you no longer have knowledge of location or movement and the spell ends.

The spell ends if the focus takes enough damage to destroy it. The rune takes the damage instead ,and is destroyed, leaving the focus intact. Additionally, any creature holding the focus must drop it or take 5d8 fire damage. If the focus is flammable it will burst into flame.
