My build for the [Tenet Detron]. I haven't tested this against the [Kuva Brakk], but I will leave the results here when I do. On paper, the [Tenet Detron] and [Kuva Brakk] are evened out, with the [Brakk] having a better crit and status chance, but the [Detron] having higher damage and better range falloff. Regardless, you can use the same build on both. I rolled magnetic so you have Radiation+Magnetic+Corrosive, for dmg to all factions (swap corrosive for heat if you want DOT's).
