Use with gladiator mods in warframe and/or melee weapon for critical chance (each gladiator mod can give up to 120 percent critical chance increase per combo, there are 6 in total which adds up to 720 percent total critical chance increase) and use with power spike from naramon focus school for melee combo duration increase. You must use at least 2 Gladiator mods in order for this build to work and power spike from naramon provides extremely good utility
so without these it would be hard to use the build unless you have other means of increasing your cit chance or combo duration

If you don't have [Voltaic Strike] then you can switch it out with [Vicious Frost]

if you don't have power spike for naramon you can switch [Melee Prowess] with [Drifting Contact] on your staff

if you don't have [Primed Fury] you can switch it out with [Quickening] or [Berserker Fury]. you can also switch it out with [Gladiator Vice] but I recommend that you put that mod on your melee for the critical chance per combo and an extra mod slot.

you can switch out [Primed Fever Strike] with [Fever Strike] or [Virulent Scourge]. [Proton Snap] is also a viable option but it is conditional for you do have to wall latch for 2 seconds to activate the buff

If you do not have [Primed Reach] then I would switch it out with [Berserker Fury] and switch out [Primed Fury] for [Quickening] since you can not have 2 types of Furys on one build but you could go with anything that suits your taste. You can also just switch it out with Spring-Loaded Blade

You Can switch your Primed Smite and your elemental damage depending on what faction you're going up against;
-If you are going up against grineer then you should keep the build as it is
-If you are going up against corpus or anything with High shields but low hp then go with toxin and a Primed Smite Corpus
-If you are going up against infested Then you could go with gas(toxin and heat), heat, viral(toxin and cold) or corrosive(toxin and electricity) and a Primed Smite Infested
-If you are going up against enemies on Deimos then you should go with heat or corrosive(toxin and electricity) since they are completely Immune to viral procs and gas does not do as much damage to them. also, use a primed smite infested because the enemies on Deimos are mostly infested.
-If you are going up against corrupted then you should use viral and a Primed Smite Corruped mod
