This [Tenet Detron] build is solely for applying as many status types as possible as quickly as possible, we lack the hidden Microwave status from [Kuva Nukor], so we can only aim for 4 status types.
The magnetic Progenitor Bonus is important as Tenet already deals Radiation damage, this gives us two combined status types for free while allowing space to add Viral (boosts damage to health up to 325% at 10 procs), and Heat (used for stripping armour up to 50%).
We can opt for [Amalgam Barrel Diffusion] over Galvanised Diffusion as we get higher initial multishot and we also get extra dodge speed, which can be useful for activating [Rolling Guard] or simply dodging damage.
For our exilus, we go with [Reflex Draw] for the Holster Speed, as warframe builds equipped with [Vigorous Swap] benefit from the holster speed, allowing us to swap to our primary or our Melee to deal more damage using [Rifle Aptitude] or [Condition Overload].
Secondary Dexterity is used to provide us with Combo Duration for our melee, and even more Holster Speed.
