I took a look at people upset about a build someone made called "Tridolons" and I kinda realized. That builds does indeed suck, it's outdated heavily.

I have decided to go ahead an see if I can make an improved and better variation of that build.

I wanted to at first make this build forma efficient, I didn't wanna see a 7 forma build. This setup is meant for quick access to get (assuming the credits and endo is no problem)

Mods:

[Blind Rage] and [Umbral Intensify]: What these mods do is they boost your strength to higher amounts allowing Eclipse and [Shock Trooper] to be boosted to really good amounts. [Umbral Intensify] is replaceable with other mods like [Transient Fortitude]. But the general consensus is that you want around 250% strength.

[Primed Continuity], [Augur Message] and [Narrow Minded]: These are as straight forwards as the strength mods too. You don't really need anything other than these three mods. [Augur Message] is interchangable with anything else you wanna add.

[Streamline] is just for that 30% efficiency bonus.The reasoning for that is because [Blind Rage] chews up your efficiency so this makes that slightly less atrocious.

[Adaptation] at R7 is there to essentially [Negate] the fact that you're squishy as hell. 90% damage resistance is never a downside. It's put at R7 so you can avoid having to spend another forma which would make this build much more expensive for no reason.

[Corrosive Projection] and [Coaction Drift] is there to enable some free damage for your weapons. But it is Interchangable for a lot of other options too. Such as [Enemy Radar] and [Enemy Sense] to find Vomalysts easily.

[Shock Trooper] is by far your most important mod in this build. It gives you an electric damage boost to your weapons which can beef up Radiation damage. With the proper strength it gives you a 243% electric damage boost.

Arcanes:

Arcane Nullifier is for when the Eidolons emit their burst upon a limb breaking, this enables you to completely [Negate] all damage from that and to not lose energy from the wave.

Arcane Energize is because you still have piss Efficiency, so you need some form of actual energy regeneration, you can replace it with something like Arcane Rise or something if you wanna use the energy drop pads (cringe)

Archon Shards:
Optimal shard setup is 2 primary electric damage shards, and 2 ability strength shards, and then finally one casting speed shard.

Setup:
Find Eidolon
Kill Eidolon shield
Cast [Shock Trooper] (283% electric damage with madurai boost)
Cast damage eclipse (85% damage boost with Madurai)
Cast one [Volt] shield (2x Critical damage, and 50% electric damage boost)
Shoot Eidolon limb.

Weapons:
The typical setup for killing eidolons with weapons is a crit based weapon modded with Radiation damage since Eidolons are weak to weak to radiation damage.
