Category:Upgrades

Upgrades are items that modify your tank's stats or behavior in some way. Most boost your tank's Hit Points, Attack, Speed, and/or Special.

Every upgrade is for a specific tank. So if you want to improve Buck's speed, you need Exhaust upgrades specifically for Buck; Exhaust upgrades for Joker cannot be used.

Upgrades can be won from season rewards and trophy rewards, they can come from chests, and they can be purchased (either for 10 gems or 1000 coins) in the store when they are available. Two new items (often for the same tank) will be available every day, and checking the "Find Items" link under a tank may sometimes uncover other upgrades for purchase.

Every unlocked tank may have one upgrade. At level 5, the second upgrade slot opens up, and at level 10, the third slot opens up.

Generally, the Common tier of an upgrade provides some small benefit; the Rare tier provides 2x the Common amount; and the Epic tier provides 3x the Common amount. In a few cases (like Medkit or Heavy Coating), the difference between ranks is smaller than the base boost, but the difference between Common and Rare is always the same as the difference between Rare and Epic.

Like many current games, upgrades can be combined in groups of three to create an upgrade of the next tier. So three common Heavy Barrels combine to create one Rare Heavy Barrel.

Upgrades sometimes drop from chests. Common chests only drop Common upgrades, Rare chests may drop Common or Rare, and Epic chests may drop upgrades of any tier. Most upgrades can be collected from Common chests and then combined to form higher-tier upgrades, but some only have Rare and Epic varieties; these upgrades must be found from Rare and/or Epic chests.

Base Upgrades, which modify your tank's stats directly, can always be stacked; putting two Common Bullets on your Joker will boost your damage by 5% + 5% = 10%. Other upgrades may or may not be stackable.
