  • The Orthos Prime's Ability polarity for its Stance slot makes it ideal for slotting in Shimmering Blight immediately. While the Orthos Prime can also use Bleeding Willow, its Bar polarity will reduce the number of its bonus mod capacity, unless changed using Forma.


  • This weapon used to have the same stats as normal Orthos. It was buffed in Update 9.5.2.
  • Note that the end-blades are not mirrors of each other and seem to have shapes that could fit together
  • Rubidium is an alkali metal element that is very soft, ductile and silvery-white in color.
    • Rubidium does not appear to be a very useful material for blades, as it is not hard enough to scratch other materials with its Brinell hardness of only 0.216MPa compared to Iron's rating of 490MPa. Being ductile, it is also easily bent, so it is unlikely to keep its shape when striking another object.
    • Furthermore, Rubidium, as an alkali metal, explodes when coming it comes into contact with water. It has also been known to spontaneously combust in air.
    • Despite the Orthos Prime's description, Rubidium is heavier than Iron, by ~53%.
