This is a basic high DPS Desert Wind build that is built assuming you will be using the Reactive Storm augment. Viral / Heat is used due to being a naturally good combo, along with the fact that whatever actual elemental weakness the enemy has will be added via [Reactive Storm].

So for example if you fight a grineer with ferrite armor, Reactive Storm will convert your Impact damage into corrosive, meaning you deal Viral, Heat, and Corrosive damage / status effects. This is far more damage then if you were to mod corrosive in the first place, because now you get the status effects of both viral increasing your damage output, and corrosive stripping armor all in one package.

[Primed Pressure Point] is used over [Condition Overload] because [Condition Overload] does not affect Desert Storms exalted waves essentially making it worthless because 99% of your melee hits will be at range, similar to [Excalibur]'s [Exalted Blade].
