During your adventures, Geralt is able to obtain Gear Upgrades that boosts your abilities and signs. Only certain armor and weapons can be upgraded, as noted by empty slots. Once applied, the upgrade can either be removed - destroying the upgrade, and making room for a new upgrade, or the item can be dismantled, and the upgrade returned.
