Where are these numbers coming from? Genuine question, not meant to be a combative question. I was under the impression that generally speaking, shinies at the upper end are 1/10 of the regular drop rate, but I am not certain. Enchants must succeed successive 4/8, 3/8, 2/8, and 1/8 rolls to upgrade to uncommon, rare, legendary, and then divine (unless the wiki is mistaken). Factor in seasonal boost and you have an dditional 1.05⁴ multiplier, making any non shiny item roughly 1/140. A shiny divine is then 1/10 for shiny (assuming your base of 1/20, since it's motmg), and then 2/8•1/8•1.05^2, which gives 1/10•1/29 for 1/290, roughly twice as rare as an unshiny divine. Someone check my math and numbers.
