Upon loading up Elden Ring Nightreign, you will be met with a short tutorial on how to play the game, along with its iconic difficult boss fight that you will actually get two attempts at this time around.

Defeating Tricepalos earns you the Blade of Night Fragment key item. Give it to the Guardian once you return to Rountable Hold, and complete the Remembrance. You get the Small Makeup Brush as a reward, a blue relic that gives the Revenant a power boost when her summoned spirits are on the field and increases Rune acquisition for the entire team.

Here's what you need to do to unlock Revenant as a playable character in Nightreign: Obtain the Old Pocketwatch by attempting four runs, or beating Gladius once. Give the Old Pocketwatch to the Priestess to unlock the Duchess. Buy the Besmirched Frame from the Small Jar Bazaar for 1,500 Murk.
