Been thinking about this for a long time.. I know using Trina is one possibility (or Tears of Karvadis for reverse items) to increase the success rate, but what about burning lots of items before upgrading the one you want to? I ve seen lots of people burning tons of wood staff+8 or even +6/+7 uniques just to use a trina and a bus for their main item. Why dont you simply do that without burning other items? In my eyes it can not increase your success rate (mathematically it is not possible). Or is it proven that burning other items before upgrading your main one really increases the success rate?
