Detect materials

You touch a non-magical object, wall, or other non-living solid substance. You sense what materials it is made of, how thick it is, whether or not it is hollow, and its shape and size. If it is over 15ft wide, long, or tall you can only detect up to 15ft and the DM only tells you the demensions up to 15ft in each direction. Additionally, the DM can be as specific or as vague as they want. If this spell tries to target a living creature or magical object or is affected by counter spell the spell fails without you knowing which was the reason it failed.
