Poseidon
by NoName_
Poseidon is a client-side Fabric fishing automation mod for 1.21.11 that runs the full rod fishing loop: cast, wait, detect the bite, reel in and recast.
What it does
Once a player starts it, the mod repeats the rod fishing cycle on its own, using timing that can be configured to look less mechanical. A status display on the HUD shows whether the bot is active, the bobber state, a live countdown while a bite signal is present, and information about the last catch. Players can open the configuration screen directly from chat by typing poseidon, and an optional sound or title screen can announce events.
Named for the Greek god of the sea, Poseidon targets fishing play on Hypixel Skyblock. It is client-side only, so servers run without it and only the player's client needs it. Poseidon depends on PlayerAPI for player input and scheduling, and on YetAnotherConfigLib (YACL) for its settings; Mod Menu is optional. The mod is published for Fabric only, with a single game version, 1.21.11, and the latest file is 1.0.0. The code is under All rights reserved and is not open source.
