Items

Items in Trancespace Fortress 2 are essential to gameplay and victory. Thet can be dropped from a lot of sources and can be sold for their prices at the shop (Commons, Rares and Epics affected by this) or 1 Mineral (Legendary, Primals, Prestige, Valor, and Legendary Unique (Legendary Shop) items).

Uncommon Items
Uncommon items are the easiest to find and cheapest to buy. They are thus also the weakest items in the game. They can be dropped from normal enemies, goblins, a few non-boss heroic units, the uncommon shop and quest rewards.

Rare Items
Rare items are easy to find and cheap to buy, although more expensive than uncommon. They are better in comparison to uncommon. Rare items can be acquired from the same areas as uncommon items except the rare shop is used, not the uncommon one. They do not stay through games.

Epic Items
Epic items are the most expensive mineral items and are midly easy to find and can be bought for a good amount of minerals. Epic items can be dropped from normal units, golins, demons (from Hell Mode mythic challenge), a few non-boss heroic units and quest rewards. They do not stay through games.

Legendary Items
Legendary Items can not be bought and can only be obtained from drops or achievements. Legendary items are generally better than Epic, Rare, or Uncommon Items, and almost all feature a unique passive or attribute. They can be dropped from normal units when hardcore mode is activated (mythic challenge), endless mode (mythic challenge) rewards, goblins, quest rewards and demons. Bosses will always drop a legendary item upon death. Legendary items that are equipped or in your inventory are saved to your account, and stay through new games. Legendary items left on the ground will be permanently lost unless they are achievement items.
