Building for Steel Path here, toxin for health and slash for armor, use the double dipping mechanic on your slash procs with primed smite mods to deal max bleed damage. Blood rush/weeping wounds for crit/status, sac steel for red crits, CO build with a good status secondary (cough [Kuva Nukor] cough). Berserker for speed, optional swap to something else if desired ([Buzz Kill], [Primed Reach], etc.) Use gladiator set mods on [Deconstructor] with an adarza [Cat's Eye] for dumb amounts of crit.
