Twinned Summoner, What can you do with your Eidolon without making it look to diferent?

[Merellin]

So, The Twinned Summoner gets a Eidolon who looks just like them. I was curious of what evolutions and things you could give your Eidolon to keep it effective, Without changing it too much so it still looks like you (So, No larger size or wings or extra arms or tentacles or such) Could you make the Eidolon still effective without taking such evolutions? This is primarily for the Chained Summoner.

[Melkiador]

The original intention is for you to use the "shared evolution" evolution to pass evolutions between the two of you to make it hard to determine who's the summoner and who's the eidolon.

The natural attack evolutions are usually pretty obvious. If you want you and your eidolon to appear to be "normal" people, then you'll want to focus more on skills and support.

Alright, Thank you Melkiador!
