Detect Presence

Until the spell ends, you are aware of the presence of creatures within 30 feet of you and learn two pieces of information about each distinct presence detected:

Creature Type. You learn the creature’s type (such as aberration, beast, celestial, construct, elemental, fey, fiend, humanoid, monstrosity, or undead).

Planar Status. You learn whether the creature is native to the plane you are currently on or extraplanar (originating from another plane).

The spell can detect creatures on overlapping planes, such as the Ethereal Plane, but it does not reveal the specific plane of origin.

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.

Casting as a Circle Spell. In addition to the spell’s usual components, you must provide a special component (a gem worth 100 GP), which the spell consumes. The spell no longer requires Concentration. When the spell is cast, each secondary caster must expend a level 2+ spell slot; otherwise, the spell fails.

The number of secondary casters determines the spell’s area of effect and duration, as shown in the table below. The spell ends early if any caster who participated in this casting contributes to another casting of Detect Presence as a Circle spell.
