Activating these golems initially requires 15 energy. There are 3 modes for this golem: Ranged, Melee, and Defensive. Once active, a player may interact with these golems and order them to change mode.
These Golems follow whoever activated them. Thus, if you have 2 or more humans, make sure puller is not the one to activate them.
When their health is depleted, these golems will simply shut down and will require another 15 energy to reactivate. This means that the golems will never be permenantly destroyed.
