Alchemy is here! (tl;dr at the bottom)

This update adds the second of the largest skills, Alchemy.
With this skill you'll be able to brew potions of increasingly advanced quality, as well as a wide range of new potions. With vanilla Minecraft you were able to brew 12 types of potions (excluding extending, amplifying, splashifying, lingering, and inversion with fermented spider eyes), now you can brew 26 types. More will be added as more skills are added, as many of the planned potion effects require the existence of these skills.

The new brewing system is designed to work the same way as vanilla potion brewing, you still use brewing stands for example and still use the same ingredients (for the most part). By default, many of the potion recipes are locked off from the player. They may unlock these recipes as they progress through the implemented skill tree.

This update also adds a new Transmutation mechanic to the game. You can brew Alchemic Precursor, which isn't very advisable to drink, but once you convert it to a splash potion and throw it on certain materials they transmute to something else. If you're advanced enough, you may even transmute iron to gold and emerald to diamond.

Aside from brewing, a couple other things have been added:
You can now specifically decide for each crafting recipe how much people can repeat-craft it (new button in menu)

A couple more dynamic item modifiers have been added

A couple more perk rewards have been added

A couple of bug fixes

You can now display EXP progress as a temporary boss bar

The wiki page on ValhallaMMO has begun construction!

Warning
This is a relatively more "dangerous" update. Because the custom brewing system required entirely overriding the vanilla brewing system, that includes inventory interactions with the brewing GUI. If you find a duplication exploit to do with the brewing GUI, notify me and I'll try to patch it right away. You can also disable the custom brewing mechanics in config.yml for the time being.

If you use ValhallaMMO's default recipes, delete your current recipes.yml file and let ValhallaMMO generate a new one and you can skip the section ahead. Otherwise, continue reading.

Since the update added a whole bunch of default alchemy recipes, you probably won't have access to these if you've previously used the plugin. If you want these recipes, back up your current recipes.yml file, delete the original one, load up the plugin so it can regenerate a new recipes.yml file, and then copy the brewing section in that new file over to your original recipes.yml backup. Then you can use that one.

TL;DR
- Added Alchemy skill and skill tree
- Added custom brewing recipes and the ability to make your own
- Added custom potion effects compatible with custom brewing recipes
- Added custom Transmutation mechanic
- Fixed some small bugs
- New default brewing recipes have been added, if you used this plugin before but only use the default recipes (none of your own added), remove recipes.yml before booting up your server. Otherwise, copy the new recipes over to your current recipes.yml
- Look out for duplication exploits with the brewing stand GUI, and disable brewing from config.yml if you find them until fixed.
