Ancient Tether

Closing your eyes, you feel the astral ley lines flowing all around you. Opening your eyes, you reach forward and touch an object or a surface, attaching a ley line to it. While this spell is active, you can always find your way back to the mark by following the astral ley lines connecting it to you.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the duration increases by 24 hours for every two slot levels above 2nd.
