Chameleon Mask

You touch a willing creature and place a minor illusion on it that allows it to blend in with its surroundings. For the duration, that creature may replace its Dexterity (Stealth) modifier with your spell attack bonus on any Dexterity (Stealth) checks it makes. Additionally, creatures that rely on sight to see, have disadvantage on attack rolls against the creature affected by this spell.

At  Higher Levels. Casting at 2ⁿᵈ level or higher you can target one additional creature for each spell level above 1ˢᵗ level.
