You want keep a Soldiers mental health under the rug ? And you say our leadership has been neutered ? <| sep |> Sure does make me feel crappy <| sep |> Just pointing out this is the one with no yogurt option in case people miss that . But if you don ' t care about making yogurt this is a fantastic deal ! <| sep |> For example , if you have 400 % MF , the chances of you finding a unique item are 236 out of 1223 19 . 3 % chance to be unique . This is incorrect . I ' m assuming you arrived at 1223 by summing up the numbers for 400 % MF , but it ' s pretty simple to show that it doesn ' t work like that . For example , you don ' t have 100 out of 400 to find uniques at 100 % MF , and you don ' t have 312 out of 2800 at 1500 % MF . Rather , compare the numbers individually as to how much more likely you are to get each type of item when it drops . D 2 first generates what base type it is , then determines rarity by going down the list roll for unique chance , if failed , roll for set , etc . If you want to really get into the mechanics of it , here ' s a very exhaustive tutorial this part is under the header Item quality selection
