Bandolier
Uncommon item (green)
Kills sometimes drop an ammo pack that makes all your skills ready again. Each extra bandolier, more often.
Game text: «18% (+10% per stack) chance on kill to drop an ammo pack that resets all skill cooldowns.»
Stacking: Per the game, 18% with one and 10% more per copy.
Watch out: The pack restores one charge, not all (turrets, magazines). It does not reset equipment. Any ally can grab it.
There is no useful number: what changes per copy is under «Stacking», above.
Drops from large chests, sometimes small ones, and green printers.
Unlocked from the start: it can show up in any run.
