Question about treat wounds on Eidolons - Lemmy.ca

Hi all! Relatively new (or new to PF2e) GM here. Last night one of my players who is playing a Summoner raised the question of whether he can attempt Treat Wounds twice every hour instead of once since his Eidolon is a separate target (ie. Someone treats the Summoner’s wounds and then immediately treats the Eidolon’s wounds). I ruled in the moment that I didn’t think that sounded right, my reasoning being that they share a health pool and the PC shouldn’t be able to double its benefits solely because of which class it is. Can anyone tell me what the RAW is here, ideally with an AON reference I can point him to?

If the summoner and eidolon both took damage from an AoE, would you only apply it once since they share hit points?
I believe the RAW in that case is for the Summoner to only take the greater of the damage it would take and what its eidolon would take. So if the Summoner succeeds the saving throw and the Eidolon crit fails the save, then the summoner takes double damage from the AOE effect.

Yes, those are the rules.

Like with your actions, if you and your eidolon are both subject to the same effect that affects your Hit Points, you apply those effects only once (applying the greater effect, if applicable). For instance, if you and your eidolon get caught in an area effect that would heal or damage you both, only the greater amount of healing or damage applies.
