Chaotic Flicker

You channel chaotic energies into your form, causing random fluctuations in your appearance. For the duration, you can use your bonus action to cause your appearance to flicker and shift in unpredictable ways. This grants you advantage on Dexterity (Stealth) checks and allows you to attempt to hide even when you are only lightly obscured. Additionally, each time you use this ability, roll a d6: on a 1-2, the flickering causes a random effect; the next attack against you has disadvantage, and you must make a DC 12 Constitution saving throw or be stunned until the end of your next turn.
