MaterialTweaker
by fonnymunkey
MaterialTweaker is a Forge utility for 1.12.2 that changes the attributes and repair materials of armor and tools through a config file.
What it does
The utility edits the material definitions that armor and tools draw on. For each material it can change durability, damage, toughness, enchantability and other attributes, and it can set which item repairs it. Wood, iron and diamond, the vanilla materials, can also have their values edited, with no separate mod needed for each one.
Repair rules can be set per material or per item. A material can accept a repair item such as leather strips for leather armor or a whetstone for iron, which lets an iron sword be repaired. A single tool can also be given its own repair item, and items that normally cannot be repaired, such as bows, can be assigned a repair material. Everything is handled by the mod's config system, and the mod is published for Forge only, with build 1.1.1 for 1.12.2 as the latest file. Servers that run it need every player to install it too.
