Infobox • Talk page

Efficient is an Invention perk that reduces the charge drain rate of the item it's on. It can be created in weapon, armour, and tool gizmos. It is the standard version of the Enhanced Efficient perk.

As Refined Anima Core and tier 90 power armour do not directly use charges from the universal charge pack, the Efficient perk has no effect on their degradation mechanics.
