Weapon Power-Up

Weapon Power-Up is a passive item from the Operation Guns DLC of Vampire Survivors.
Weapon Power-Up is added to the level-up item pool after obtaining any weapon from the Operation Guns DLC. The item may appear to occupy a passive item slot, but the inventory doesn't count it toward the passive item limit. Consequently, the player will still be able to acquire an additional item, even if the passive item inventory appears to be full. Although it does not take up space, an empty passive item slot is still needed in order to receive the Weapon Power-Up from level-up choices. 
For each Weapon Power-Up acquired, Revival is increased by 1 and a random weapon in the player's inventory that is not at its maximum level is upgraded by 1 level. Every weapon in the Operation Guns DLC requires and consumes it for evolution, in addition to a distinct passive item required by a weapon. Upon being consumed, the Weapon Power-Up will disappear from the inventory and return as a level-up choice, but the player will keep its conferred bonuses.
Up to 4 Weapon Power-Ups can be found as stage items on Neo Galuga.
