  • The Orthos Prime's Zenurik Pol polarity for its Stance slot makes it ideal for slotting in Mod TT 20px Shimmering Blight immediately. While the Orthos Prime can also use Mod TT 20px Bleeding Willow, its Naramon Pol polarity will reduce the number of its bonus mod capacity, unless changed using Forma.
  • The Orthos Prime (and its normal counterpart the Orthos) has a unique equipped normal attack animation where it performs thrusting and stabbing attacks against an enemy. This attack is completely replaced upon equipping any of the polearm Stance mods.
  • The Orthos Prime's immense range (especially with Mod TT 20px Primed Reach) on top of having decent attack speed allows it to build up combo counter exceedingly fast in a relatively crowded environment, making it a viable candidate to Mod TT 20px Blood Rush and Mod TT 20px Body Count build to compensate its relatively low stats in late game environment.


  • Prior to Hotfix 9.5.2 (2013-08-12), this weapon used to have the same stats as normal Orthos.
  • Note that the end-blades are not mirrors of each other and seem to have shapes that could fit together. The blades are asymmetrical.
  • 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.
