The weapon awakening system was introduced in Epic 8.
Awakening a weapon will add adjustments to its statistics. The adjustments may be positive or negative. A weapon which has not been awakened is described as dormant.
Click the Dismantle icon in the inventory window. Place an empty pet card in the dismantle window and click "Dismantle All" to obtain awakening stones. Click the Enhancement icon in the inventory window. Place a dormant weapon in the primary slot and an awakening stone in another slot. Click "Enhance" to apply random adjustments.
If the random adjustments are not to your liking, you can return the weapon to its original dormant state using a Sealing Scroll purchased from the Cash Shop.
