To unlock Revenant in Elden Ring: Nightreign, follow these steps:
- First, unlock the Duchess character:
- Obtain the Old Pocketwatch item by either completing or attempting the Tricephalos Expedition four times, or by defeating the boss Gladius, Beast of Night.
- Take the Old Pocketwatch to the Priestess at Roundtable Hold and give it to her to unlock the Duchess.
- After unlocking the Duchess, go to the Small Jar Bazaar in Roundtable Hold.
- Purchase the Besmirched Frame relic for 1,500 Murk from the Small Jar Bazaar after the Duchess is unlocked.
- Once you buy the Besmirched Frame, a quest marker for Revenant will appear on your map in the eastern wing of Roundtable Hold.
- Head to the marked location and interact with the Revenant phantom near a portrait of Radagon.
- Choose to "Touch the phantom?" to be teleported to a special arena.
- Defeat the Night Idol boss in this arena.
After defeating the Night Idol, Revenant will be unlocked as a playable character in Nightreign. Revenant is a necromantic spellcaster who can summon slain enemies as allies, making her a distinctive combat class. Unlocking her requires first unlocking the Duchess and acquiring specific items, notably the Besmirched Frame relic and completing the Night Idol boss fight.
