This is a x2 permanent combo throw and heavy attack detonation spam build which creates forced slash procs.
Make sure you are holding melee fully to perform a charged throw, then pressing heavy attack to detonate mid air.
Stance : This doesn't matter at all since you will only be throwing and detonating heavy attack repeatedly.
Sacrifial Steel: Mandatory CC mod, doubled for heavies i.e. gives +440% crit chance for 140% final cc on heavy attack.
Primed Pressure Point: Mandatory damage mod, can swap out if using a frame with additive dmg buff eg Chroma/Octavia/Limbo
Killing Blow: Gives additive damage but extra wind up speed makes throw spam much more bearable.
Amalgam Organ Shatter: Mandatory CD mod, also gives wind up speed
Volatilie Quick Return: Increases blast radius by 3m
Primed Smite: Swap depending on faction you're facing, but generally you would only be using [Glaive Prime]'s forced slash against Grineer or Corrupted enemies with armor. Faction mods double dip DoTs, giving 2.40125x damage multiplicative to other dmg mods.
[Corrupt Charge]: Gives initial combo to hit x2 combo, which deals double heavy damage. This can be kept at rank 2, because rank 3 alone does not increase the heavy attack bonus past x2.
[Power Throw]: This is OPTIONAL, but [Power Throw] is a multiplicative damage boost like Eclipse (giving up to 4x final damage multiplier) but requires you to perform a 'catch and throw' combo where you hold the throw button just before the Glaive returns, which will do a special animation, then release to throw again. You can explode with alt-fire and hold throw button again to chain catches until 3 stacks. If you prefer not to deal with this combo, just swap Power Throw for Gladiator Might or a Riven.
Dispatch Overdrive: Optional, but gives bonus 60% movement speed for 15s.
Melee Duplicate: Nearly doubles overall damage. The optimum CC for Melee Duplicate at 3.7 crit damage is actually 131%cc. A heavy detonation on Glaive Prime with just Sacrificial Steel is 140%.
