Weapon gizmos charged with perks can be used to enhance the weapon's abilities. As a one-handed main hand slot item, the Augmented chaotic rapier can hold 1 gizmo, allowing up to 2 perks.
Using this weapon in combat can gain experience to increase its level. Levelling the weapon will have no effect on its ability in combat, but it will improve the experience and materials gained for disassembling it.
The Augmented chaotic rapier uses charges stored in the universal charge pack. When the charge pack runs out of charges, the item loses stats and gizmo effects, and can also no longer gain any equipment experience. Function will resume when the pack is recharged with divine charges.
Your current drain rate for a tier 80 main-handed weapon is given by the following table. It depends on your current reduction researched, the item level, and Efficient/Enhanced Efficient perk presence.
