To add more methods of making money, we added Custom Fishing! This means you can gain various types of fish, various types per biome and various lengths and rarities!
Just attempt to fish as you normally would, there's then a chance you get a custom fish with a various length or rarity.
You can then sell this fish at /warp spawn, by clicking the signs in the beacons.
note : There is only one mythic fish available, it's extremely rare!
