Earth Sense

By touching your hand to a solid surface, you briefly sense the presence of all solid material within 30 feet of you, so long as it is in contact with the surface you are touching. You learn the size and shape of every object you sense, and you can tell whether an object is made of stone, metal, wood, flesh, or some other material.

This spell can detect the presence of creatures, but not liquids.

At Higher Levels. When you cast this spell using a spell slot 2nd level or higher, you can sense objects 30 feet farther away from you for each level above 1st.
