OneClient SkyBlock — download the Minecraft modpack for Hypixel SkyBlock

OneClient SkyBlock is a separate Polyfrost client modpack for Hypixel SkyBlock players. It combines dedicated mods, HUD elements, OneConfig settings and performance tools in one package. It is not a server plugin or a standalone JAR file.

OneClient SkyBlock features

The developers include add-ons they selected for Hypixel SkyBlock: SkyHanni, Skyblocker, SkyOcean and Odin. The project also lists Meowdding’s SkyBlock Item List, IQ Addons and Iconographic. The exact included mods and their versions can change between releases.

OneClient also includes the OneConfig and PolyCompose interface systems, as well as EvergreenHUD and VanillaHUD. The SkyBlock edition focuses on in-game information and quality-of-life features for that mode rather than general single-player use.
