Boon Companion and Eidolons.

[bigrig107]

Does Boon Companion affect Eidolons?

This is for PFS.

[Calth]

No, an eidolon is neither an animal companion nor a familiar, it is its own special category. For PFS, you are out of luck I believe, but in a home game I would say it is not unreasonable to apply it.

[wraithstrike]

Nope and that is in and out of PFS.

[bigrig107]

Dang it.
There goes that interesting build.
