Pronto Beam evolution recipe

Answer: Max C-U-Laser, collect Weapon Power-Up, and evolve it into Pronto Beam

Keep Tiragisu in your inventory. It does not need to be maxed. Open an eligible chest after all requirements are ready.

Steps

1. Obtain C-U-Laser and raise it to maximum level.
2. Collect Weapon Power-Up during the run.
3. Keep Tiragisu in your inventory. It does not need to be maxed.
4. Open an eligible chest after the requirements are complete.

If it does not evolve

• Confirm that C-U-Laser is at maximum level.
• Confirm that Weapon Power-Up was collected in the current run.
• Confirm that Tiragisu is in your inventory.
• Open the chest only after the requirements are complete.

Weapon Power-Up is consumed by an evolution. To evolve another Operation Guns weapon in the same run, obtain another Weapon Power-Up from a level-up choice or stage pickup.
