Hi, i won't combine unique stuff if i don't get the stuff i want to upgrade two times (and i combine the worst of the two) And, i will try to farm magic rare and epic stuff, combine them for try to have legendary stuff, and combine the legendary stuff to try to have an unique ! And for the combination when i said 10 time 2 items or one time 10 item i mean you combine items 2 per 2 , but you have item for do it 10 times, but if you do the 10 items you can only do it one time. So for exemple, if combine 2 items have 10% to get higher one and combine 10 items have 90% to upgrade, Doing 10 time 2 item would be 100% chance of getting better stuff, while combine 10 item one time is 90% chance ! But i don't know the statistique of combine 2 or 10 items 😅
For the souls i'll use all of them for drawn items, but i don't get that much ( around 100 per week and i can still get 120 from ranking, 960 from infinite tower, around 1150 from hardcore infinite tower), but i don't know if it will be enough for get a complete set or a good stuff (probably not)
