Is your sword sharp? Maybe it's a bit longer than normal? Wait, is your helmet dented?

Introducing Quality Tools!

Description:

This mod gives tools, armor, and weapons random qualities when they enter your inventory, inspired by Terraria tools. All the qualities, as well as the tools that can get them, are completely configurable.

Here are a few more examples:

It also adds a 'reforging station', which you can use to change your tool's quality. 

Use the reforging station by placing your tool in the top slot, and the material you would use to repair it in the bottom slot, then clicking the button.

If the tool isn't normally repairable, there is a config file that has custom reforging materials for it. For instance, iron ingots for shears. You can add materials there for modded tools that don't have repair items.

It should automatically use tools and their repair items from other mods as well, like these leggings from Botania.

There is also support for Baubles, so any items that can go in baubles slots can get qualities. As an example for this, and in case you don't have any other mods that use baubles, I added a simple emerald ring and amulet (which can be reforged using emeralds).

Installation Instructions:

Install this as a regular forge mod (there are many tutorials out there if you don't know how).

It also requires Potion Core as a coremod:

That's about it! You can use this mod in modpacks if you like, and remember to report any bugs that you find. If you want to post a comment, you should do so on the minecraftforum page, as I will be more likely to see it.

Enjoy the mod!
