Canderous Ordo protected by an Arkanian energy shield An energy shield of Arkanian design was a compact device, attached to the forearm, intended to provide a higher degree of defense compared to standard armor. This specialized forearm shield offered defense to the user from extreme temperatures, specifically both hot and cold conditions. Furthermore, it guarded against weapons that utilized energy and sonic attacks. If the power cell within the device was overloaded, either from absorbing too much damage or from being used too frequently, it would fail. This failure necessitated a complete replacement of the shield unit.
