Synthesist Summoner and Infernal Healing

[Isles]

When a Synthesist Summoner is damaged, he loses the eidolon's temporary hitpoints first. Would infernal healing heal both the summoner and the eidolon's temporary hitpoints together? If not, would it heal the summoner and then the eidolons hitpoints?

Thanks

There is an issue with the synthesist having the temporay hit points because there isent really a game maecanic that can restere temporay hit points. So no.
Most folks i know play it like synthesist temp points can be regained by the summoner spells that heal the Eidolon but only them. But i am sure some play with it like it is normal hitpoints.

Summoner: How does a synthesist (page 80) heal damage to his eidolon?

Because the eidolon gives the synthesist temporary hit points rather than having a separate pool of normal hit points, effects that cure hit points don't restore the eidolon's temporary hit points. This technically leaves you unable to heal the eidolon. To remedy this, effects that specifically restore hp to an eidolon (such as rejuvenate eidolon) restore temporary hit points to a synthesist's eidolon. This does mean those spells end up as a sort of must-have "spell tax" for synthesists, but the advantage of being a synthesist is your eidolon's hp are a buffer between you and damage, unlike a normal summoner who can be targeted separately from his eidolon.

Even the Fast Healing evolution, or other fast healing or regeneration effects, restore hit points rather than temporary hit points, so they heal the summoner, not the eidolon's temporary hit points.

It's a real shame they nerfed the heck out of the synth archtype for PFS play, then banned it from play and left it a mess with FAQ's/Errata meant to balance it for organized play. The synth archtype tends to be heavily houseruled in most groups I know of (and several posters have said it is just outright banned in their groups).

I let it ride RAW. I know. I live dangerously like that.
