Refinery items

Refinery items add an extra effect to a piece of gear; the effects themselves and how to make them permanent are on Refinery and Dragon Souls. Most come as packs: right-click one and you receive a random item of that effect. Every pack is made for certain gear, and its grade (Primary, Medium or Superior) sets which three values you can get.

Each range shows the lowest and highest of the three values a pack can give. Critical Strike is a chance of a 1.5x physical hit, Skill Critical Strike a chance to double magic attack, Breakthrough a chance to go past max attack, Immunity a resistance to critical hits, Counteraction a rate of blocking Breakthrough, Detoxication less poison damage, Block a chance to halve damage and Penetration a cut to the target's magic defence.
