User blog comment:Furkan Zomer/Possible Solution - Cursed BBI Weapons and Armor lv.3/@comment-2.221.175.151-20130628203820/@comment-3068131-20130630171612

I looked through most of the comments now,

it seems like most people are reading it all in the same time, please just keep it at Armor or Weapons until you completly understand it, the contributor above me, you are confusing the Armor and the Weapons which will obviously result in it going wrong.

Ok in your case lets say you got 5 Weapon lv.2's and the 3rd is the Hallowed Dragon or the Bane Archistaff, just get 3 Weapon lv.3's just purify 3 of both(3 Lv.2's and 3 Lv.3's, so 6 in total) this WILL result in you getting the Sanguine Stalk
