Bey-Blade [Valkyr]

This build is intended for Valkyrs using '[Eternal War]' augment for WarCry and a reasonable amount of Power Strength(I use 3Umbrals and [Augur Secrets] for a total of 190% power strength) The Strategy is to Spin 5 times, and then pause or Slide Attack and continue to Spin, if you occasionally stagger at least with [Valkyr]'s Warcry the stagger won't last too long.

The build devours everything. including Sentients.. except Noxs' because you're spamming the [Whirlwind] attack and you cannot easily headshot, but it only takes a few extra swings to tear them down as well.

Alternatives(Bold is my personal Alt)
If you don't have a Riven you can use Either(suggested in this order)
Gladiator Might (60%Crit Damage)
Volcanic Edge(you would want Corrosive/Heat)
or... the popular [Condition Overload]

If you want to use this on someone other than [Valkyr] i would suggest using your Prefered Attack Speed mod, in place of Either... the before mentioned Riven Slot, OR you could swap
[Drifting Contact] for either
Berserker or [Primed Fury]

You can also Swap [Sacrificial Pressure] for [Primed Pressure Point] because it does slightly increase your DPS, but it's also a preference.. i like the extra Critical Chance.

Some weapons require a lot of Forma to be built, I am just glad the GramPrime has good starting Formas where even fitting in both Sacrifical only takes 3 Formas..
(4 if you want to trade [Drifting Contact])

This will take you into all the end game content especially if you enjoy only Melee as a [Valkyr Prime] main <3

EDIT: Lastly.. Don't forget you can use [Deconstructor Prime] with the Gladiator Mods as a Stat stick for more Crit Chance per Multiplier.
