Easiest way to raise alchemy?

I got to level 5 Alchemy in a few days by just fusing level 31 Blue Sneakers and I didn't use any of those fatique resets on that account. Mining and Crafting are the easiest to level up, others require a bit more effort.

i find crafting to be pretty hard, considering anything that isn't arrows requires 2+plates and some sort of crystal, while rings require one plate and no crystals all the way up to 6~7

alchemy does get progressively harder though, haven't delved much into it, but i think what you are doing is the best way:X
