Crates

Crates are grab bag-type items which can be hooked 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 using. They can also be placed.

Wooden Crates (most common), Iron Crates, and Golden Crates (rarest) can be caught anywhere. 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, the crate priority is, from highest to lowest, Corruption > Crimson > Hallowed > Dungeon > Jungle > Sky. For example, when a Floating Island is Corrupted and changes to Corruption, Sky Crates will no longer be harvested.

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: 1/150 (0.67%); Corrupt Crate: 7/750 (0.93%); Iron Crate: 7/250 (2.8%); Wooden Crate: 7/125 (5.6%). The Crate Potion doubles these chances.

Tips

 * Crates can also supply a few other Hardmode items:
 * As stated above, the Anchor and Enchanted Sundial 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 7/225 (3.1%; instead of 7/250 or 2.8%) and Wooden Crates with a chance of 14/225 (6.2%; instead of 7/125 or 5.6%).
