To evolve a weapon, the player needs to fulfill several conditions:

• The base weapon needs to be level 8 (both in a union).
  
• The player needs to have the required passive item of any level (in an evolution).
  
• The player needs to collect a Treasure Chest that drops from a champion spawned after the 10:00 minute mark.

However, there are some exceptions regarding the last point:

• The first chest in Mad Forest dropped by the Glowing Bat, which spawns along the wave at 1:00, can evolve a weapon.
  
• All chests in Dairy Plant, Il Molise, Cappella Magna and Boss Rash can evolve a weapon regardless of time.
  
• Treasure Chests that contain an Arcana (minutes 11:00 and 21:00 in every normal stage) cannot evolve a weapon.
  
• The character Gyorunton can evolve weapons with any chest pickup that gives an item, regardless of other conditions.

Other exceptions:

• In the case of Infinite Corridor, Crimson Shroud, and Sole Solution, all related passive items must also be fully leveled.
  
• In case of gifts, aka Bracelet, Bi-Bracelet and Super Candybox II Turbo, a passive item is not needed.

On evolution, the base weapon is removed and the evolved weapon is added. On union, both base weapons are removed and their union is added.
