Telltale Dust
Casting Time: 1 action
Range: Self (15-foot emanation)
Components: V, S, M (a pinch of chalk dust and a dried moth's wing)
Duration: Concentration, up to 10 minutes (concentration)
Description
You cast a handful of fine chalk dust into the air, and it refuses to settle. For the duration, a 15-foot emanation of restless motes surrounds you, and anything moving through that space stirs them.
An invisible or hidden creature that enters the emanation or starts its turn there is outlined by the disturbed dust and is revealed to you. You know its location, attack rolls against it don't have disadvantage for being unseen, and it can't hide from you while it remains in the area. The creature is not made visible to anyone else, and cover it would otherwise have still applies.
A creature that knows about the dust can move at half speed to slip through it undisturbed, making a Dexterity (Stealth) check contested by your Wisdom (Perception) check to remain undetected until the start of its next turn.
At Higher Levels
When you cast this spell using a spell slot of 2nd level or higher, the emanation increases by 10 feet for each slot level above 1st.
