Your ONX Ultimate server, with the useful bits included.
Host your ONX Ultimate server
ONX Ultimate is a broad Minecraft 1.12.2 adventure and RPG pack for CreeperHost hosting, combining technical progression, magic, exploration, and creative building. Its Forge-based collection brings together a wide range of systems for players who enjoy shaping a long-running world around several different play styles.
A varied modded adventure
ONX Ultimate offers a substantial kitchen-sink experience with technology, automation, magic, dimensions, and exploration. Thermal Expansion, Mekanism, Ender IO, BuildCraft, Applied Energistics 2 Unofficial, ProjectRed, and Solar Flux Reborn support engineering and factory projects.
Magical progression includes Thaumcraft, Blood Magic, Electroblob’s Wizardry, Ancient Spellcraft, Reliquary, and Thaumic additions. These systems provide arcane alternatives to purely technical development, with powerful items, research, and spell-focused gameplay.
Exploration beyond the Overworld
The pack expands discovery through Biomes O’ Plenty, The Aether, Advent of Ascension, Twilight Forest, Dimensional Doors, and Galacticraft. Players can encounter new landscapes, travel through unusual dimensions, and pursue adventures beyond familiar Minecraft terrain.
Storage and construction tools such as Iron Chests, Storage Drawers, Chisels & Bits, and OpenBlocks Reopened add flexibility for organising materials and creating detailed builds. Tinkers’ Construct extensions, Iron Furnaces, and decorative additions further support custom bases and equipment.
Simple pack management with CreeperPanel
CreeperPanel provides one-click modpack installation and updates for ONX Ultimate. Updates preserve configuration changes, helping keep personal adjustments intact while the pack advances. Built-in tools help manage files, mods, configurations, players, inventories, worlds, and backups from one panel.
CreeperHost uses game-server hardware selected for strong native CPU performance and stability. DDoS protection and location choice are included, while diagnostic tools help investigate lag and review the settings behind a modded world.
Support for modded communities
CreeperHost has experience hosting modded communities since 2011, with real support staff available when questions arise. Eligible Premium and Pro services can also use Ask Theo to inspect the current panel state and prepare safe next steps for approval.
Together, these tools make it easier to maintain an ONX Ultimate world while preserving the pack’s mix of technology, magic, exploration, and creative building.
Got questions? 
Yes. CreeperHost modpack pages link into ordering with the selected pack ready to install. You can also change versions or pick another supported pack later from CreeperPanel.
CreeperPanel is built around real modded servers, including update paths that aim to preserve user configuration changes where supported instead of treating every update like a fresh install.
Eco can work for lighter packs, but Premium is the recommended CreeperHost range for modded Minecraft. Premium gives stronger hardware, Turbo Start, Bonus Memory, and Ask Theo where enabled.
