Does Deadly Aim's % OA buff work on Guardians of Empyrion?

If my OA goes up because of Deadly Aim (Inquisitor), do Guardians of Empyrion (Oathkeeper, player scaling pet) get a higher OA too as long i got the buff up?
Because i would only assign a devotion (Phoenix in this case) if they do get the higher OA.

Yes.

No, don’t do that. Phoenix’s interaction with player pets is weird. They will get the aura instead of you. Meaning you’ll get none of that dmg absorption.

Well that was obvious, i am a idiot. Thanks for the info. Now i can rethink.

No. Adcth works alright. Just the auras. Bat on Storm Totems or Wind Devils is the classic.

Yes.
