Edit: Replaced quite a few mods and added [Condition Overload] and [Quickening] instead of both sacrificial mods to adapt to the status revamp this while keeping the three gladiator mods in your [Helios Prime] wich give you better results as of now.

High level enemy meltdown if you're running a friendly [Helios] with a couple of gladiator mods in it, it will supplement [Gladiator Might] reaching about 274% crit chance.
[Organ Shatter] can be replaced with amalgam if you need that wind up for heavy attacks, personally I'd rather have it as is, this build doesn't need a riven whatsoever, so no need to sell your esteemed anasas for plats thank you very much.
