The Cosmere is a universe devised by Brandon Sanderson, encompassing many worlds, each with their own variation of magic. This mod aims to bring all of that to Minecraft itself... eventually.
There are currently several powers from Scadrial, the planet from the Mistborn series:
Allomancy!
Become a Misting or Mistborn! Consume certain types of metals based on the power you start with and burn it to access your allomantic ability!
Feruchemy!
The End-Neutral art, where you get out what you put in! If you have access to feruchemical abilities, that is.
Twinborn & Compounding!
The place where the powers of allomancy and feruchemy meet.
Still not enough for you?
Well there's always the third metallic art of Scadrial...
Surgebinding - The Stormlight Archive
Earn the trust and respect of one of the Radiant spren in order to gain access to the ranks of the Knights Radiant.
AonDor - Elantris
Find a way to gain access to the powers of the Planet Sel and gain access to a more advanced magic.
Awakening - Warbreaker
The art of combining color, Biochromatic Breath and an awakening command in order to animate an object.
New Dimensions
Perhaps the cognitive realm may interest you... Better find the nearest perpendicularity!
(Required!) CuriosAPI - because there's always another secret™
JEI - because recipes are forever plentiful and who wants to have to google them all the time.
HWYLA - Going to be including ways to get more info out of what you're looking at!
Patchouli - because I love well done in-game wiki/guidance (which mine is not well done... or at all existing, yet. I will get to it!)
