What are some good feats for a Synthesist (This is what I picked up)

[8 Red Wizards]

I picked up Half Elf for the extra points. I was wondering if the Eldritch Heritage tree would be worth it for a synthesist, and what Bloodline would be worth taking with it. Also would Augment Summoning boost up my Synthesist bio-suit if I used the ritual or summon eidolon spell. If you can think of any other feats that would be worth putting in there or better than what I posted I would like some input.

eldritch claws?

You could take Feral Combat Training and then snag some style feats. Going Dragon Style to add an extra 20% of your strength bonus to all your claw damage would be nice.

If you take the orc bloodline as a heritage feat at the improved level you get a scaling +2 inherent bonus to strength.

[Caderyn]

Orc bloodline doesnt work with synthesist as your natural form gets a +2 strength bonus which is incorporated into your base stat, which is then Overridden by the eidolons bonus when summon it, only gear bonuses or tomes used while the eidolon is summoned would apply bonuses directly to the eidolon (as in that case the inherent bonus would be to the eidolons ST score and not your own).

As far as I remember, the consensus is that Augment Summoning does work on the summon eidolon spell. It is not applicable when using the normal ritual.

You need Resilient Eidolon if you plan to buy the "large" evolution, for the same reasons Barbarians take Raging Vitality.

I believe I made calculations at home a while back that showed that at lower levels Arcane Strike was better than Power Attack.

Improved Natural Attack will only provide marginal damage increase and can be replaced with something else without mourning.

If I may : be really careful when building your synthesist (and have someone else review your character for errors if you can). Synthesist is the most error prone class of all Pathfinder. I still catch involuntary mistakes on my player's Synthesist almost every level up. :D

I use Summon Eidolon more than any other spell so Augment Summoning & (Spell Focus (Conjuration) could be worth it. I'm starting to think the Eldritch Bloodline feat might not be worth it for Synthesist since I was only going to get it for flying, but I decided to just pay the points for it. I'm going to look at Dragon Style for sure.
