Detect Magic

1st-level (divination; arcane, divine, nature, senses) [ritual]
Class(es): Bard, cleric, druid, paladin, sorcerer, wizard
Casting Time: 1 Action
Range: Special (30-foot radius
Target: Self
Components: V, S
Duration: Concentration (10 minutes)

Until the spell ends, you automatically sense the presence of magic within range, and you can use an action to study the aura of a magic effect to learn its schools of magic (if any).

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

Cast at Higher Levels. When using a spell slot of 2nd-level or higher, the spell no longer requires your concentration. When using a spell slot of 3rd-level or higher, the duration increases to 1 hour.
