Orthos Prime

The Orthos Prime features a higher base damage, range, and attack speed than the Orthos. The Orthos Prime was added into the game in Update 9.

This weapon can be sold for 5,000.

Characteristics
This weapon deals primarily damage.

Advantages:
 * Can attack continuously while sprinting without disturbance using the quick melee attacks.
 * High base attack speed.
 * Long range attacks with a wide radius.
 * Large jump attack AoE that knocks down enemies, with a chance of inflicting a proc.
 * This allows it to knock down even more enemies, past its normal slam radius if a nearby enemy is affected.
 * 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.
 * Normal attacks have awkwardly placed swing hitboxes which vary with each swing animation, making it more difficult to hit enemies.

Comparisons:
 * Compared to Orthos:
 * Higher base damage (65.1 vs. 50.0).
 * Higher damage (9.8 vs. 7.5).
 * Higher damage (9.8 vs. 7.5).
 * Higher damage (45.5 vs. 35.0).
 * Higher critical chance (10.0% vs. 5.0%).
 * Higher critical damage (2.0x vs. 1.5x).
 * Faster attack speed (1.17 vs. 0.917).
 * Longer reach.

Trivia

 * This weapon used to have the same stats as normal Orthos. It was buffed in.
 * Note that the end-blades are not mirrors of each other and seem to have shapes that could fit together. The blades are asymmetrical.
 * 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.
 * This could possibly relate how it can inflict a proc, even when contacting land.
 * 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.
 * Along the blade reads the text "The longest arm is the law," written in the Tenno alphabet. This might be a hidden joke, referring to the Orthos Prime Handle being substantially longer than the Orthos' handle.
