Here’s our Vampire Survivors weapon evolutions guide. Learn everything about evolutions and unions in Vampire Survivors.
Vampire Survivors Weapon Evolutions
Evolution is a game mechanic in Vampire Survivors which upgrades a weapon into a stronger version of itself using a passive item.
Union is a combination of two weapons, which may or may not also require a passive item as a catalyst. Once two weapons are united, you will obtain a free weapon slot.
Evolved weapons usually inherit most of the weapon’s normal mechanics, along with a buff somehow connected to the stat boost of the passive item used for the evolution. For example, the Fire Wand, which shoots damaging projectiles, is merged with the Spinach, a passive item that increases damage, to create Hellfire – a weapon which now passes through units, dealing damage to more enemies at a time.
How to Evolve your weapon
For evolution to take place, you need to fulfil the following three conditions:
- Have a base weapon upgraded fully. Most weapons must be upgraded eight times before an evolution can take place.
- Have the base weapon’s passive item counterpart in your inventory. It doesn’t matter which level it is.
- Find a treasure chest. You can find a treasure chest by defeating a boss.
