Blurry Mist

You touch one willing creature (including yourself). Until the creature takes an action, they are cloaked in a blurry black mist.  The mist radiates in a 10-foot radius, centered on the target.  The mist gives disadvantage on any attacks on the targeted creature made within the 10-foot radius.  Additionally, the target receives advantage on all stealth rolls for the duration.

 For every level the spell is cast above 2nd, the caster can target 1 additional creature.
