How Do I Increase Weapon Rarity?

UnlikeBlack Ops: Cold War Zombies, playersdo not have an armory stationavailable for easily upgrading weapon rarity in the game. When players deploy,equipped weapons will always start as common weapons,and players will have tofind better weapons or aether tools to upgradeand increase the rarity of the weapon. Players canincrease their chances of finding rare weapons by operating in the threat level II and III areasof Urzikstan and can take advantage of the wall buys or the mystery box when in these areas to guarantee the acquisition of a weapon.

If players do not want to depart from their weapon equipped at deployment, players will need toscavenge the mission area to find an aether tool that correlates to a rarity higher than the weapons' current rarity.Since weapons start at common rarity on deployment, any aether tool found will upgrade the rarity of the weapon to match the tool (i.e.a rare aether tool will upgrade a weapon to rare), althoughan aether tool of lower quality or matching quality will have no effect on a weapon(i.e. an uncommon or rare aether tool cannot be used with a rare weapon).
