Logical Enchanting
Logical Enchanting changes how the anvil calculates the experience cost of combining enchanted items, so the Too Expensive limit no longer blocks ordinary work.
What it does
The mod replaces the vanilla anvil cost formula with its own calculation. Enchantment costs are no longer tied to a hardcoded table that depends on each enchantment's maximum level, which means enchantments added by other mods, including those capped above level 5, can be combined without a fixed penalty. Prior work penalty is still tracked, now with a more careful count of earlier combinations, and the anvil cost check that produces Too Expensive is removed.
Logical Enchanting is a server-side only mod for Fabric and targets 1.21.11 only, with the latest file 1.0.1 dated 2026-03-22. Only the server needs it; players connect without installing anything. The anvil user interface is updated on the server side, so the displayed cost matches the adjusted value. Because the source code is public, server owners can read how the formula was changed.
Key features

Experience cost for combining items is computed from a new formula instead of the vanilla enchantment table.

Prior work penalty tracking
The mod keeps counting prior work penalty across combinations, including those done in vanilla.
Removed Too Expensive check
The maximum experience check on the anvil is removed, so the cost is no longer capped at the vanilla threshold.
Anvil display adjustment
