Armour gizmos charged with perks can be used to enhance the armour's abilities. As a legs slot item, the Augmented Ahrim's robe skirt can hold 2 gizmos, allowing up to 4 perks (2 on each). Using this armour in combat can gain experience to increase its level. Levelling the armour will have no effect on its ability in combat, but it will improve the experience and materials gained for disassembling it.
