With the new Tenet weapons being released, we find a laser beam assault rifle with high fire rate and decent reload speed. The [Tenet Flux Rifle] features very little down time with a 120 bullet magazine with a 1.7 second reload speed.
We will be using five Forma for the mastery xp from the weapon, much like normal Kuva Lich weapons. Also like previous Kuva Liches, your current warframe will determine what innate element the weapon will have. These are known as the progenitor. For this build we will be using heat as our element, but you can use Heat/Radiation/Toxin.
It can be noted that Infected Clip can be traded out for it's 60/60: [Malignant Force]. This will lower your sustained dps but will increase the status. Due to the high fire rate, I feel the 26% status chance is plenty. The new [Galvanized Chamber] mod offers 10% less multishot but almost doubles it after 4 kills. [Heavy Caliber] offers a massive 165% damage increase at no drawback due to the 100% accuracy. It’s worth noting that you could use [Hunter Munitions] in place of [Vile Acceleration] and preform higher sustained dps in higher level content. If you bring this to SP then it would be worth it. Also, I find that the [Flux Rifle] specific mod [Flux Overdrive] doesn’t provide enough of a damage increase over [Vile Acceleration] to warrant using. It still seems like a niche mod that could have a place in certain circumstances. I would recommend experimenting with those two mods over the [Vile Acceleration] if you are running a frame like [Wisp] or [Gauss] due to the immense fire rate increase that might be bottlenecked by it’s 1.7 second reload speed.
