DISCONTINUED. MOD WILL BE SPLITT UP INTO MULTIPLE MODULES (Multifarious: ...)

While this mod was made with the intention of using it for an upcoming modpack, I was thinking that maybe some of you want to use features in your own worlds and packs. So here it is - almost everything is datapacks so anyone can edit it. I will add a wiki the next week, make sure to report all bugs/issues and join the discord to be up to date. This mod can be added/removed to existing worlds without messing with anything.

Currently Implemented:

Ring Crafting (Craft Rings that improve your stats, uses the trinket system)
Quality (right now just for rings, any ring you craft rolls a quality up to legendary, improving its final stats)
30+ Weapon models (check screenshots!)
Spell & Mana System (apply runewords to gear to get active spells while wearing it, video below)
If used with the mod Identity some abilities will transform your character
New ways of obtaining items
Jundles (Jar + Bundle, alternative implementation of bundles, using clay/bricks)
Plates (upgrade your gear from stone to netherite and keep its enchants and abilities)
Pocket Geodes (Obtain them by mining ores, they contain gems and runes)
Rune Crafting (Runewords, Weapons, Cosmetic Particles)
Status Effects & Custom Particles (Leader of the Pack, Bleed)
Gems (Obtained from pocket geodes, used for crafting and as enchanting alternative)
Everything can be changed/adjusted/added/removed via datapacks

Planned:

Similar to Rings -> Necklaces
Gear Modifiers & RNG stats on gear (example: apply a zombie heart to your chestplate, get a roll on bonus health)
A ton more spells & runewords, currently there is only one.
Weapon specific abilities (right now weapons are not balanced but that will make sense later)
3D Armor models
Mob specific drops used for crafting
Unique Weapons that aren't craftable and have their own abilities and models

Compatibility:

Identity: if you use this mod together with identity to get the animal transformations - make sure to go through its config files and turn most things to false. I could not manage to ship custom ones but maybe in the future.
Origins: if you want to use other origins mods or the default ones, you need to make a datapack and change the layer file for coolstuff, replace:true -> replace:false
