Nibelungen is generally a support unit that attempts to steal objects, buff neighboring units, and calls in Gyges to attack. It also has the benefit of two shield arms and a shielded core. A powerful blast is needed to knock it off its guard and damage it effectively. It is also one of the only units that traverse both the Sociel and Nox landscapes.
Gyges is a miniature attack unit. Its generally fragile but it has a powerful long lasting attack with a long cool down and charge. Its a good practice to get rid of these immediately as they can quickly become a threat if not handled. I’ve also had the idea that Gyges could also be a portable grappling hook point allowing the player to grapple in multiple locations.
