Detect Evil and Good

For the duration, you know if there is an aberration, celestial, elemental, fey, fiend, or undead within 30 feet of you, as well as where the creature is located. Similarly, you know if there is a place or object within 30 feet of you that has been magically consecrated or desecrated.

The spell can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.

At Higher Levels. When you cast this spell using a spell slot of 3rd or 4th level, the duration is 1 hour. When you cast this spell using a spell slot of 5th or 6th level, the duration is 8 hours.
