Similar to Fusium, it is relatively easy to extract in the form of large nuggets. Actium can primarily be found on asteroids within the Athos belt. However, it can also be extracted on many lands if miners dig deep enough. Actium crystals emit a bright green light and have a tendency to focus the light toward their base. Actium's unique properties allow humans to change the molecular conformation of any type of material, bending the matter and thus rapidly improving any unit. Therefore, Actium's main purpose is to level up units.
