Crates

Crates are grab bag-type items which can be caught while fishing, containing random loot such as ores, bars, potions, accessories, and other items. In addition, biome-specific crates can contain biome-specific loot. Their content can be unloaded by pressing the button, either on their icon in the inventory or while holding them. Crates can also be placed.

Some kinds of crates can be caught anywhere, while the rest can only be caught when fishing in a certain biome. Wooden Crates, Iron Crates, and Golden Crates ( or in Hardmode, Pearlwood, Mythril, and Titanium Crates, respectively) can be caught anywhere, with Wooden/Pearlwood being the most common, and Golden/Titanium being the rarest. In general, rarer crate types contain more valuable loot. Biome Crates, which are exclusive to the, are slightly less rare than Golden Crates and can contain items otherwise found only in the matching Biome Chests. When fishing in an area with multiple biomes, only one biome crate type can be caught; for example, when a Floating Island is Corrupted and changes to Corruption, Sky Crates can no longer be harvested. See Fishing for details on which biomes take precedence over others.

Crates are caught every 1 in 10 catches, on average; with a Crate Potion, the chance is doubled to 1 in 5. The kind of crate the player obtains is dependent on their Fishing Power, with higher Fishing Power increasing the probabilities of rarer crates. As an example, fishing with a Fishing Power of 100 in a lake of at least 300 valid water tiles in the Corruption would yield crates with the following probabilities: Golden Crate: ; Corrupt Crate: ; Iron Crate: ; Wooden Crate:. The Crate Potion doubles these chances.

Tips

 * On the, it can be beneficial to fish for crates during pre-Hardmode, save them for later, and then open them up in Hardmode, in order to get Hardmode ores without breaking any Altars. This has the added benefit of not spawning random Ebonstone/Crimstone or Pearlstone in the world, which can be a side effect of breaking Altars.
 * On the, crates fished during pre-Hardmode will no longer drop Hardmode items, even after the Wall of Flesh has been defeated.
 * Crates can also supply a few other Hardmode items:
 * As stated above, the Anchor and are only found in crates.
 * Corrupt or Crimson Crates can contain Cursed Flames or Ichor, respectively, and both can have Souls of Night.
 * Hallowed Crates can drop Crystal Shards and Souls of Light.
 * The higher the Fishing Power, the greater the chances for crates. See Fishing Power and Fishing § Tips for information and recommendations about how to increase Fishing Power.
 * The chance to catch a Iron or Wooden Crate increases if the player is not in a biome where a biome chest can be caught (i.e., not Corruption/Crimson, Hallow, Dungeon, or Jungle, and below sky level – an example could be the pure caverns). With a Fishing Power of 100 and a lake of at least 300 valid water tiles, Iron Crates are then caught with a chance of (instead of ) and Wooden Crates with a chance of  (instead of ).
