This build is intented as a stat stick for frames like [Khora] or [Gara]
You can change drifiting contact for [Body Count] for a bit of extra combo duration, but it you will need to add a forma (any polarity is fine), it's just 2 more seconds on the combo but sibce there isn't a need for more status it's a personal choice. If ypu have primed mods go for them, but again you will need to invest forma.
With both [Primed Fever Strike] and [Body Count] this would be a 2 forma build
Blueprint can be purchased at infested lab in the clan dojo, [Drifting Contact] is rewarded by rotation B on nightmare missions, [Weeping Wounds] can be gotten as deimos bounty mission reward, [Blood Rush] also comes from deimos bounties as well as lua spy vaults.
Equip [Helios]' [Deconstructor] with gladiator mod set for more crit chance
