Barlowe unlock guide: evolve Optical Shot into Acerbatus

Quick answer: evolve Optical Shot into Acerbatus

Barlowe unlocks when you evolve Optical Shot into Acerbatus. Albus starts with Optical Shot, so unlocking and selecting him first removes the need to wait for the weapon in level-up choices.

Who this guide is for

• You want the exact requirement for unlocking Barlowe.
• You need the passive item and levels for Optical Shot.
• You want the next objective after unlocking Albus.

Unlock steps

1. Unlock Albus.
2. Start a run as Albus and raise Optical Shot to level 8.
3. Obtain Karoma's Mana and raise it to level 5.
4. Open an evolution-eligible chest to obtain Acerbatus.
5. Confirm that Barlowe is unlocked.

Karoma's Mana must reach its maximum level of 5. Merely owning the passive item is not enough for this recipe.

If the evolution does not appear

• Confirm that Optical Shot reached level 8.
• Confirm that Karoma's Mana reached level 5.
• Open an evolution-eligible chest after both items are ready.
• Check that you leveled Optical Shot rather than another ranged weapon.
