This is a x5 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.

UPDATE OCT 2024
[Galvanized Reflex] gives 5x combo now

UPDATE JULY 2024
[Melee Elementalist] now provides an additional 1.9x multiplier to slash procs and also gives Heavy attack windup.
Power Throw is now flexible for Killing Blow.

MOD BREAKDOWN

• 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

• Melee Elementalist: Multiplicative 1.9x to slash procs.

• 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.

• Galvanized Steel gives 5x combo after kills

• [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 Killing Blow, 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%.

RIVEN STATS

You want CD/DMG/IC. Replace either [Power Throw] (based on preference) or [Killing Blow].
Note you don't want more CC since this makes Melee Duplicate worse.
Note you don't want heavy efficiency as a negative since that is a desired stat for x12 spam crescendo builds.

ELEMENTAL VARIATIONS

Corpus/Casual corrupted: You can slot [Primed Fever Strike] over Primed Faction (or [Power Throw]) to deal toxin damage which bypasses shields simultaneously with slash procs to bypass armor.
