EIDOLON FARM BEST BUILD - https://overframe.gg/build/176530/

For weapon you only need Sniper (I use Rubico Prime - https://overframe.gg/build/176532/)
For amplificator you need Raplak + Propa + Certus (If you don't have Little Duck Reputation you can use Raplak + Shraksun + Lohrin)
To break Eidolon's shield with amplificator, use [Volt]'s shield and middle click (With Shraksun you need to be close to the Eidolon)
You need to use Madurai Focus for Void Strike capacity (The longer you stay invisible with your operator the more damage you will do)
To break Eidolon's part, use your sniper with [Volt]'s shield(s)
The max stack for the shield is 6, after this number, damage will no longer increase (For operator and sniper)
[Natural Talent] is really good for fast cast of shield
[Hunter Adrenaline] is for Energy Regeneration (only in warframe)
[Preparation] is really good for have energy max when you start (you can be without)
[Adaptation] is really good against the 3rd Eidolon and for Eidolon Proc when you break one part of him
Zéro Arcane is really good for counter Eidolon Proc when you break one part of him
(You can use Energy Pad if you want)
