- Radahn Festival: Defeat Starscourage Radahn in Caelid.
- Nokron, Eternal City: Access Nokron via the crater left by Radahn's defeat. Obtain the Fingerslayer Blade.
- Renna's Rise & Ainsel River: Use the portal in Renna's Rise to reach Ainsel River Main. Find the Miniature Ranni doll.
- Lake of Rot & Astel: Traverse the Lake of Rot and defeat Astel, Naturalborn of the Void.
