Spawn Test Eidolons in the Simulacrum?

[Mados.sys]

There's not a really efficent way to test your amps completely without forgetting about the Eidolons (at least as long as i know, i can't test Amps against Eidolon shields), you can test them against Grineers, Infested, Corpus and yada yada, but the only way you can test them against Eidolon's Shields is to fight them in the Plains, and its hard to test them being attacked all the time, and having multiple options being Madurai, Unairu, Arcanes, Abiliys that can boost the Amp's damage (Volt's Shield, Ember's ring of fire) makes it even harder to test and it would take awfuly long to have a definitive result.

I want this "Test Eidolon" in mainly because i have to stick mostly with the Cetus Amp 2-2-3 and it's becoming seriously boring to use it to be efficent, and i would love to test new amps and synergys to have fun trying new things without fearing that i wouldn't be able to Solo Tridolons. (And I have to, potato pc, meaning that i can't play with other people)
