Weapon gizmos charged with perks can be used to enhance the weapon's abilities. As a two-handed item, the Augmented attuned crystal bow can hold 2 gizmos, allowing up to 4 perks (2 perks each).
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 attuned crystal bow 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.
The augmented attuned crystal bow can be reverted to seed at the singing bowl in Prifddinas. All weapon XP, augmentors and gizmos will be lost and an attuned crystal weapon seed recovered.
