I. Refinery

Refinery grants equipment extra attributes and enviable buffs. Different types of equipment require different Refinery items.

Just like your equipment, Refinery items have 5 quality levels (Normal, Refined, Unique, Elite and Super), and so there will be five levels of Refinery. 

Refinery Items

There are 3 types of packs: Primary, Medium and Superior packs. The qualities of the Refinery items you'll get from packs are randomly decided by the system but are still subject to the pack quality.
