can blood shards give any legendary or set item in the entire game?
i am basically asking because i want to upgrade the current weapon i have got, but it is the same weapon i want, i have currently only had 2 of this weapon drop with only 1 being ok (i am currently using it) so wanted to know if it is wasting blood shards going for it through shards.
Yup :), they can.
Any item, apart from items exclusive to bounty caches, that is.
I looked at your profile in your other post, and I would definitely hold off gambling for a weapon until you've completed one of your sets though, like Sunwuko or Raiment.
