Enchanting Disguise

You touch a mask, bandages, or a similar object used for disguises with a touch of illusion to make it seem more convincing. For the duration, a humanoid wearing the object adds your spellcasting ability modifier to one of the Charisma checks it makes, then the spell ends.

When you reach certain levels, you can enchant more objects with a single cast of this spell: 2 at 5th level, 3 at 11th level, 4 at 17th level.
