Obtained from a strongbox at the Shrine of Azura after helping the Nerevarine during the mod's quest. Alternatively it can be obtained by killing the Nerevarine during the quest as a death item.
WARNING: If you kill the Nerevarine, the next time you go to sleep he will appear in a dream and place a powerful curse on you. Check Active Effects and you’ll see the Curse of Azure. The curse reduces your Health by 50 and your Speech by 25. The curse is permanent and cannot be undone. Your actions also change how the villagers of Little Vivec interact with you. Selyse at the Tradehouse will no longer sell or buy items from you and Bal-Ran will no longer train or speak with you.
The ring instantly kills the player if worn.
