Essence of Lily

A thick violet mist coalesces into a projectile within your hand. The projectile remains there for the duration and obscures your hands, making whatever's held within unable to be seen. The spell ends if you dismiss it as an action or if you cast it again.
You can also attack with the projectile, although doing so ends the spell. When you cast this spell, or as an action on a later turn, you can hurl the projectile at a creature within 30 feet of you. Make a ranged spell attack. On a hit, the creature has disadvantage on all attacks made until the end of its turn as the projectile then scatters into a 10 ft. lightly-obscuring mist. A creature you hit with this Cantrip cannot have its Torpor lower than an amount equal to half your Proficiency Bonus.

Torpor. You may expend an amount of Torpor equal to half your Proficiency Bonus to change the mist to heavily-obscure the targeted area.

At Higher Levels: The amount of creatures that can be targeted at once with the spell attack portion of this spell increases by 1 when you reach 5th level (2 creatures), 11th level (3 creatures), and 17th level (4 creatures).
