AnvilXpFix
by Mobzilla24
AnvilXpFix changes how the Forge 1.12.2 anvil prices repairs and enchantments, so costs are counted in flat experience points instead of the vanilla exponential levels.
What it does
In vanilla 1.12.2 the cost of an anvil operation grows exponentially with each repair or enchantment, so a tool can reach the Too Expensive limit after a few steps even when the work is basic. Much of that cost is hidden raw experience that the player never sees. AnvilXpFix replaces this logic with a flat experience calculation, so the price of each operation stays easier to follow.
The mod is built for Forge 1.12.2 and is needed on both sides. The server handles the new experience math, while the client keeps the experience bar and anvil interface in step with the changed costs so they update without visual glitches. The author notes that the mod was made because no existing fix targeted this version, and it was uploaded in case it helps others. It is lightweight and sits alongside other 1.12.2 mods.
Key features
Flat experience costs
Repair and enchantment costs are calculated from flat experience points rather than exponential anvil levels.
Fewer Too Expensive stops
Basic repairs and enchantments no longer push an item past the anvil limit as quickly as in vanilla.
Targeted logic change
Only the anvil cost logic is altered, leaving the rest of the anvil behavior as it is.
Synced experience display
The experience bar and anvil screen are updated on the client so the new costs display without glitches.

Use cases
Long-running tools
Players who repair and enchant the same tool many times can keep working on it without hitting the Too Expensive limit as early.
Modded 1.12.2 packs
Pack builders on Forge 1.12.2 can add the fix to a list that already includes other equipment and utility mods.
Who it’s for: Players and server owners running Forge 1.12.2 who want anvil repair and enchantment costs to use flat experience points. Because the mod must run on both sides, it suits servers and clients that all install it together.

What the author says
In Vanilla Minecraft 1.12.2, Anvil costs are exponential, therefore as you repair or enchant an item, the cost eventually becomes "Too Expensive," and even a basic repairs/enchants consume a massive amount of "hidden" raw experience points. Anvil XP Fix surgically changes this logic. Instead of using exponential…
