Skyblock Companion

Players use the mod to compare acquisition routes for an item, including buying intermediate materials. For each crafting tree it lists required coins, estimated taxes, return on investment and break-even prices. A budget, a batch size and a maximum operation count limit the search, and the operation count is capped at 23. Bazaar order summaries feed instant-trade slippage estimates, and warnings flag shallow depth or incomplete liquidity data. A route can be pinned, or left unpinned so it follows the lowest-cost option.

The mod also covers shard relationships, letting players browse possible fusion trees and check fusion opportunities against current market prices. Crystal Hollows runs can be tracked with crystal locations and run history, and the Metal Detector helper and King's Scent Temple state tools provide optional route guidance. Crystal Nucleus builds a custom HUD and scoreboard without taking over the character mod. Required libraries are Cloth Config API, Fabric API, Fabric Language Kotlin, Hypixel Mod API, SkyHanni for Hypixel SkyBlock, Skyblocker • Hypixel Skyblock and YetAnotherConfigLib (YACL). Mod Menu is optional and gives access to the configuration screen.

It is installed on the player's side alone, so servers need nothing. It is published for Fabric only, for 26.1.2 and 26.2, under the Apache License 2.0, and the code is not open source. Estimates are based on the data available and are not guarantees, and the mod does not automate gameplay.
