Notes[]
- 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 can be thrown up to 25 meters away, which is not affected by range mods. The distance is, however, affected by the shield's flight speed and thus can be modified using mods that change projectile flight speed such as Jet Stream.
- 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 within the appropriate range of the enemy).
- Pressing the Heavy Attack button will create an explosion and cause the Shield to return to the user. This explosion has a base damage of 50 Blast and a 4m radius.
- The shield can be thrown up to 25 meters away, which is not affected by range mods. The distance is, however, affected by the shield's flight speed and thus can be modified using mods that change projectile flight speed such as
- 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.
- The shield can, however, still be thrown straight down by holding + E while looking down. This is due to the newer melee system allowing the user to force an aerial combo instead of performing a ground slam by using this technique, rather than a characteristic of this weapon in specific.
- The shield can, however, still be thrown straight down by holding
- 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 or Impact).
- The throw attack statistics aren't affected by combo multiplier or combo multiplier mods.
Tips[]
- 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.
Trivia[]
- 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.
