⚔️ Bosses & Dungeons

Dangerous dungeons and forgotten structures are scattered across every dimension, hiding bosses, traps and unique loot. Every dungeon is a step up in difficulty – and in rewards.

Deep beneath the surface and far beyond the Overworld, ancient guardians wait in silence. From the scorching depths of the Underworld Arena to the icy halls of the Frozen Prison and the ruins of the Acropolis, each location tells its own story – and each one is guarded by something that does not want you there.

Bosses are not just bigger mobs. Every fight has its own attacks, patterns and weak points, so learn them, gear up and come prepared. Defeat them to claim powerful weapons, rare materials and equipment you can’t get anywhere else – the key to pushing your progression further.

🏭 Create & Technology

Start with a waterwheel, end with fully automated production lines. With 30+ Create addons you can automate ore processing, crafting and resource gathering.

Love building machines? Create is one of the biggest parts of the pack, with 15+ quest chapters dedicated purely to technology guiding you from your first gears to massive steam-powered factories. Dozens of addons expand it far beyond the base mod – new machines, trains, logistics, decorations and whole new ways to play.

Prefer swords over cogs? That’s fine too. Create is a path, not a requirement – the pack is built for RPG players just as much as for engineers. Build as much or as little as you want, and go adventuring whenever you feel like it.

Whether you’re an engineer, an adventurer or both – there’s a place for you here.

🪄 Magic & Mysteries

Learn spells, find ancient artifacts and combine magic with your machines to gain abilities no engineer could build alone.

Beyond the gears and steam lies a world of forgotten power. Several magic systems are waiting to be discovered – each with its own spells, rituals and secrets. Collect spellbooks, master new schools of magic and turn yourself from a simple adventurer into a true archmage.

The world is full of mysteries. Hidden ruins, strange relics and enchanted equipment reward those who dare to explore. Gear up in magical armor, wield legendary weapons infused with arcane energy and take on enemies no sword alone could defeat.

Whether you focus purely on spells or mix magic with your weapons and machines, it gives you new ways to grow stronger and take on the challenges ahead.

🌌 Dimensions

Travel beyond the Overworld and discover two completely new dimensions, each with its own world, creatures and challenges.

Twilight Forest is a dark, enchanted realm hidden beneath an endless twilight sky. Explore ancient forests, labyrinths and towering strongholds, and fight your way through a chain of bosses that unlock the next part of the dimension step by step.

Eternal Starlight is a dimension under a sky full of stars and falling light. Wander through glowing forests and strange landscapes, discover new materials and face creatures you won’t find anywhere else.

🛡️ Armor & Weapons

Dozens of new armor sets and weapons with unique bonuses. Collect full sets and gear up for the toughest bosses in the pack.

From shining knight armor and samurai sets to mage robes and enchanted blades, there is equipment for every playstyle. Many sets give extra bonuses when worn together, so it’s worth hunting down every piece.

Some gear can be crafted, while the best equipment has to be earned – found in dungeons, dropped by bosses or hidden in other dimensions. As you progress, your gear grows with you and lets you take on bigger challenges.
