Deadly slashes from the Sigma sword are matched only by the force of the Octantis shield when thrown from the air.

The Sigma & Octantis is a sword and shield combo, available through the Daily Tribute system. This weapon features a special throw attack, which throws the shield at an enemy, staggering them and opening them to finisher attacks for a brief period.


This weapon primarily deals Slash b Slash damage.




  • Sigma & Ocantis is exclusive to the Daily Tribute system. It will become available every 200 days, beginning at day 300, until chosen as the Milestone reward.


  • The throw attack is done by simply tapping the melee button while in mid-air; holding down the button is not necessary, which makes it very fluid.
    • The shield is thrown ~25-30 meters away, which is not affected by range mods.
    • Holding the melee button will however make it easier to perform the finisher (if the melee button has been held down after performing an attack and an enemy is in a state where a finisher can be performed [unaware, staggered, or asleep] then the finisher will automatically occur when you enter appropriate range of the enemy).
  • Throw attacks can be done both while the weapon is fully equipped or with a quick melee attack.
  • The thrown shield has a slight homing effect, similar to thrown Glaives, though it is still capable of missing.
  • The throw attack can be done in any direction (dictated by your aim), and therefore the usual downward melee slam attack is done by looking straight down.
  • Throw attack's finisher window can be overwritten by almost all other animations or stuns (such as a Heavy Gunner's ground slam animation, or elemental proc stuns like Electricity b Electric or Impact b Impact).
  • Throw's statistics aren't effected by combo multiplier or combo multiplier mods


  • Equipping Final Harbinger, Blood Rush and Gladiator Mods allows users to quickly boost the Sigma & Octantis's critical chance.
  • The throw attack's stun can sometimes stagger enemies out of range of melee attacks, making it difficult to perform the finisher before the stagger wears off.
  • Throw attack seems to home in on the closest enemy rather than the enemy being aimed at, making precise targeting difficult.


  • Sigma & Octantis likely refers to the southern star σ Octantis (Sigma Octantis) whose position near the southern celestial pole makes it the southern hemisphere's pole star.
