SMUI - Super Anvil

The mod adds a Super Imbalance Anvil block to the world, along with two artifacts that change how enchanting works at it. A player applies the block to combine enchantments and the levels add together, so 1 + 1 gives 2, 2 + 1 gives 3, and the chain continues until the level cap is reached. The block is designed so that failed upgrades cost far less than they do on the standard anvil.

The Kalter Stability Artifact lowers the chance of an upgrade failing, and at its strongest it brings the failure chance to 0%. The Rintor Luck Artifact raises the chance of gaining extra enchantment levels and can push the success chance up to 90%. Both are meant for pushing enchantments to high levels. Because the crafting recipe needs high-level enchanted books and rare materials, the block sits at the end of progression, so players reach its full power only after they have worked through the game.

SMUI - Super Anvil runs on client and server, so the server and every player need it. It is published for NeoForge only, with the 1.21.1 build at version 67.69, released 2026-03-29 under the MIT License. The code is not open source.
