guaranteed unique
implement a vendor that sells a standard unique for you class once.
this vendor will only sell the unique once you have found 50 uniques.
so if you find a unique, you also get unique coin .
once you receive 50 coins you can cash it for the unique you need for your build.
that’s how dumb it is to get let’s say the crone staff or tempest roar, as these 2 uniques are on the ultra rare unique drop table.
