Ok guys, so you know those quests above level 40ish where you have to collect items and bring them to an npc to get exp/items?
Continually do the quest to get 7 unique items, once you have 7 unique items of the same type (Armor,Engine,Booster,Thruster,One-handed sword,two-handed sword, etc.) you can exchange those 7 uniques for a +1 of the same type.
Using this system:
You exchange refined/uniques/elites for +1's of the same type. Using the bugged quests in combination with this system, it basically means u can have +3 or better even at a lower level, only bad thing is that it might take awhile to collect 7 uniques.
Therefore, 14 Quest items collectables = 7 uniques = One +1 Item of that type.
