Riven Priorities:
1. Critical Chance, 2. Critical Damage, 3. Attack Speed. For no riven, [Primed Fury] is a good alternative.

Combo this build with Naramon and [Helios] equipped with all gladiator melee mods and a frame with the rest of the gladiator set.
For the frame, [Inaros] is most viable as for survival he needs little to no energy and is able to equip the gladiator mods without having to [Sacrifice] other viable mods.

Recommended Inaros Build

I use this setup everywhere and it never disappoints.
