Backup Magazine

The Backup Magazine is an unlockable common item in Risk of Rain 2. It allows for the players second skill(mouse 2 by default) to store an additional charge per stack.

Completing the Flawless Challenge unlocks this item.

Character Synergy

 * While this is a straightforward upgrade for most characters, the Engineer can already hold 10 charges on their Pressure Mines, and each stack just increases this amount by one. More charges to the skill will not increase the maximum number of deployed mines.


 * The Artificers Charged Nano-Bomb fires automatically when it gets fully charged, and if the button is kept down the second charge may start charging before the button is released. This causes the next Nano-Bomb to launch with barely any power.
