this is basically the 4 main elements + 8 "sub-elements"/element combinations from a random magic system idea i've had for a while
the main 4 elements are fire, water, earth, and air which are in the middle of each quarter section of the circle (i know those are overused but what else are the main ones supposed to be lol)
unlike other magic systems, instead of there being a single combination for each pair, there is instead two elements, with one being the "major" element and the other being the "minor" element
for example:
major earth + minor water = nature/plant magic
major water + minor earth = ice/snow magic
also another thing in this which i haven't seen much of is that opposite elements have no combinations (no fire/water combos, and no earth/air combos)
ok that's probably enough words in this post, but if you want to know what each sub-element is, feel free to ask in the comments (also it would be fun if someone tried to guess what the rest of the element combinations are, though a few of them aren't too easy to guess)
