How to Configure the Maximum Repair Cost and Compatibility Rules

Reading and setting the max level

The mod uses a maximum repair cost value that decides when an anvil operation is allowed. The default is 39, and setting it to 0 switches to automatic calculation.

1. Run /noexpensive maxLevel to see the current value.

2. Run /noexpensive maxLevel <level> to set a new ceiling. A higher number allows more expensive operations.

3. Set it to 0 if you want the mod to decide the limit on its own.

Managing enchantment compatibility

If two enchantments still refuse to merge, you can define a compatibility rule manually.

1. Identify the two enchantment IDs you want to allow together.

2. Run /noexpensive compatibility PUT <enchantment> <enchantment> with those IDs.

3. Retry the anvil operation; the pair should now merge.

Practical tips

  • Raise maxLevel before enabling combineHigher, since higher-level merges cost more.
  • Keep a large XP reserve; the mod removes the block, not the cost.
  • Use /noexpensive combineHigher to confirm whether past-cap merging is active before troubleshooting an anvil.
