Tremorsense

By touching a willing creature, you can grant temporary access to tremorsense. This enables the creature to "see" moving creatures that are in contact with the ground (or other solid or liquid surroundings) within 30 feet of your location as if using your eyes.

You must be on the ground (or in contact with the same liquid or solid) for the ability to work.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the range of the gained tremorsense increases by 5 feet for each slot level above 2nd.
