I think it'd be worth to update this post with official changes to the color system. Currently I can only find scattered info: https://royals.ms/forum/threads/update-91-02-04-24.231159/ official notes on the change but it doesn't explicitly define what "stats" means for both weapons and armor, which is the whole point of the change https://royals.ms/forum/threads/feedback-request-item-color-system-change.220531/page-2 goes into more detail but this is really just supposed to be the draft, and you really have to dig for this info
So godly stat +0 to +5 distributes evenly with probability 1/6, and chaos scroll -5 to +5 with prob. 1/11. Does that apply to pre-godly stat/ATT too? I recently farm balrog shoulder pads, and 13 out of 21 pads are 2/2/2/2. Is it bugged?
