You can use the following trinkets.
Glass Dust
As a Bonus Action, you can throw this pouch at a point you can see within 10 feet of you, filling a 5-foot-radius Sphere centered on that point with glittering dust until the start of your next turn. A creature that enters the Sphere for the first time on a turn or ends its turn there has the Invisible condition. This condition ends early for a creature that leaves the Sphere, makes an attack roll, deals damage, or casts a spell.
Horn-Rimmed Glasses
As a Bonus Action, you can cast Disguise Self without a spell slot or components.
Martini Glass
As a Bonus Action, you can cast Charm Person without a spell slot or components.
