 * Relatively high attack speed. Faster attacks than Orthos.
 * Long range attacks with a wide radius, even wider than the regular Orthos.

 * Stance slot has polarity, matches Shimmering Blight stance.

Disadvantages:
 * When swinging you will be reduced to a walking pace, starting on the third combo animation.

Trivia

 * 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
 * In real life, Rubidium is an alkali metal element that is very soft, ductile and silvery-white in color.
 * It is not good for a blade as it's not hard enough to scratch other materials. (Brinell hardness of 0.216MPa, thousands of times worse than iron, which has 490MPa).
 * Being ductile, it is also easy to bend, so it won't keep an edge (or any shape for that matter) when striking an object.
 * Rubidium, as with most alkali metal (like Sodium), oxidizes violently when coming into contact with water, sufficient to produce a small explosion.
 * It can spontaneously combust in air, so it is usually stored in sealed containers with an inert liquid (mineral oil) as a buffer.
 * Despite the Orthos Prime's description, Rubidium is actually denser than Iron, by ~53%.
 * Rubidium has useful properties in laser science, atomic clocks, nuclear physics research, and solar panels. This can lead to speculation that the "rubidium" in the Orthos blade is either some kind of engineered material or it is used to focus/channel something.
 * It is also possible that Rubidium in the universe of Warframe is based on Rubedo, and therefore a different chemical or material altogether.
