Nathan Graves unlock guide: evolve Sonic Whip into Crissaegrim Tip

Quick answer: evolve Sonic Whip into Crissaegrim Tip

Nathan Graves unlocks when you evolve Sonic Whip into Crissaegrim Tip. Sonia Belmont starts with Sonic Whip, so using her avoids waiting for the weapon in level-up choices.

Who this guide is for

• You want Nathan Graves's exact unlock condition.
• You need the passive item and levels for Sonic Whip.
• You want to limit the Curse added by Skull O'Maniac.

Unlock steps

1. Unlock Sonia Belmont and start a run as her.
2. Raise Sonic Whip to level 8.
3. Obtain Skull O'Maniac. Level 1 or higher satisfies the recipe.
4. Open an evolution-eligible chest to obtain Crissaegrim Tip.
5. Confirm that Nathan Graves is unlocked.

Skull O'Maniac works at level 1 for this recipe. Because additional levels also strengthen enemies through Curse, you do not need to maximize it when character unlock progress is the only goal.

If the evolution does not appear

• Confirm that Sonic Whip reached level 8.
• Confirm that Skull O'Maniac is in the loadout.
• Open an evolution-eligible chest after both requirements are ready.
• Confirm that the evolution result is not sealed in the Collection.
