Cursed

Using the Genie's Bracers three times may end up with you Corrupted (which is called 'curse' in-game). This effect changes your body uncontrollably, and spreads to any nearby NPCs over time.

You can use the console commands or a friendly custom NPC, such as Atem, to break your curse for you. The Genie fragment in Levant Tower can also break the curse.

To uncurse yourself with the console, press F1 to open it, ensure you are targeted (use target <Your Character's Name> if needed) and then use the purify command to remove the curse. This won't restore your former shape, however.
