Arcanum Unbound
by PurpleDustus
Players who want a magic progression built on personal power can start with Arcanum Unbound, a dark-fantasy mod for Forge and NeoForge that centers on mana, sigils, relics and corruption.
What it does
Arcanum Unbound adds magic artifact crafting, so a wizard builds stronger items from materials gathered during play. Power comes from mastering mana, sigils, relics and the forbidden soul mechanics, and the author describes the system as experimental, with a philosophy of sacrifice in exchange for strength. Progression is unstable by design: knowledge has to be earned, and the rewards carry a price.
The mod keeps the vanilla world as its base and adds rare, dangerous discoveries and new dimensions to explore. A visual corruption layer appears as a player moves deeper into the Abyss and becomes infected. Structure Compass support and Expanded Curios integration for relic builds are listed as compatible additions. Files are published for 1.20.1 and 1.21.1, with Forge builds and NeoForge builds, and the mod runs on client and server, so both the server and every player need it. The license is All rights reserved, so the code is not open source.
Key features
Magic artifact crafting
Artifacts are crafted from gathered materials, letting a wizard improve their power step by step.
Mana, sigils and relics
Mana, sigils and relics form the core of the power system, and mastering them is what grants strength.
Corruption and the Abyss
A visual corruption layer shows infection gained in the Abyss, changing how the player looks and feels in the world.
New dimensions and discoveries
New dimensions and rare, dangerous discoveries add to exploration without replacing the vanilla structures.
Curios integration
The mod uses the Curios API for relic slots, so relic builds can sit alongside other equipment.

How it compares
Arcanum of Wisdom is open source under the MIT License and runs on Forge and NeoForge for 1.20.1 – 1.21.1, so it offers the same loaders and range with open code. Reliquified Artifacts covers 1.20 – 1.21.4 on Forge and NeoForge and is not open source, so it reaches a wider set of versions. Arcanum Unbound stays on 1.20.1 and 1.21.1 and is also closed under All rights reserved.
