this build lets you slam the ground as fast as your fingers or macros will let you, you may also want to use arcane strike to get even more attack speed out of your radial slam attacks

[Primed Smite Infested] (or any other faction mod you want) and [Seismic Wave] will max your damage with radial slam attacks, subsuming rhinos roar onto [Nekros] will allow you to further increase the damage you deal with radial slams

[Amalgam Ripkas True Steel] + radial slam attacks will near guarantee that you split every single enemy in half at the torso, giving you more loot from desecrate

[Tek Gravity] gives you a 20 meter SUC range, by having default range on [Nekros], you can activate terrify (15M range) for a full armor strip, while pulling them towards you with [Tek Gravity], eliminating the worst part about terrify (the enemies running away after getting fully armor stripped) just make sure to only activate terrify when a Tek circle buff is active etc to activate [Tek Gravity]

[Life Strike] will give you TONS and i mean TONS of constant health, meaning you wont need to worry about toxic procs at all, you can just heal right through it, be careful as this wont prevent you from getting one shot, so bring a strong warframe build, either arcane blessing + [Adaptation] and maybe even [Health Conversion] since you will have plenty of health orbs floating around
