This is a build for the [Rubico Prime] that i suggest having if you do not have a Riven. I have a Riven in place of cold damage, but it performs just as well against Eidolons. Eidolons are weakest to Radiation damage, and you will be hitting good crits with this build, possibly red crits with [Volt]’s shield. Heavy Caliper barely affects your accuracy, and adds bonus damage. With rhis build, you can expect to one to two shot limbs.
