Unmending is a very simple mod that nerfs Mending without making it useless. Should you install it, you'll find the following changes in your game:
Items that already have the Mending enchantment will no longer repair with XP.
Mending can no longer be applied as an enchantment.
Applying a Mending book to an item resets the "extra repair cost" that accumulates as you repair an item, thus preventing "Too Expensive!". You can do this as many times as you want.
This is an updated and ported version of Vazkii's mod Unmending.
