Your body is now basically made of formless smoke that you can shape at will, whether it's to become corporal or not.
You have phenomenal cosmic power, enough to warp reality and grant wishes. Genie generally follow three rules though when granting wishes. No wishing for more wishes. No bringing back the dead. No messing with free will. It's up to you if you decide to follow them but be warned. For all a genie's cosmic might, a lot of them still ended up sealed.
You may create a magical artifact to inhabit and wait for unassuming mortals to rub it, granting them master status.
You may twist your master's wishes into monkey's paws if you wish as long as you grant the spirit of them, if not the actual literal meanings.
You are ageless and immortal, the passing of a thousand years is just like a single day in regarding your memories.
You do not need to eat, have bowel movements or even sleep if it wasn't obvious.
