Boon Companion Equivalent

[Hubaris]

Hello Advice Forum!

A short one this time. I could have sworn I read a feat that acted as Boon Companion but for Eidolons, though I've never been able to track it down (if it exists). I know there is Magical Enigma (Story), but that wasn't it at all.

Was I just imagining this Feat or does it actually exist?

Thanks!

Maybe it was 3PP?

If it exists, it's 3p. There is no such feat for first party.
