Critique my Eidolon please (PFS)

[LibraryRPGamer]

Hi Everyone,

I've been working on this Eidolon build for some time now. Please take a look and see what you think. Any and all advice is welcome.

Background:

This Eidolon was once a BBEG assassin who gave his life to save an innocent as his final act ala Tale of Two Cities. He has now been given a second chance to prove himself. If he fights on the side of good he can earn himself an improved afterlife. His celestial parole officer (the summoner, an Aasimar) guides the Eidolon through this endless trial.

I imagine the Eidolon as a sort of risen martyr. Basically, a lawful good shade/wraith.

Build:

Biped
HP 6, AC 13
DR 1/evil (Aasimar FCB)
Saves +3/+1/+2

Falcata (two handed):
Attack +3, Damage 1d8+4, 19-20x3 (10% ctit)
Avg Dmg 8, Avg Crit Dmg 24

STR 16, DEX 12, CON 13, INT 7, WIS 10, CHA 11

Perception +12, Stealth +13

Evolutions:
Claws x2 (free)
Legs (free)
Arms (free)
Skilled Perception (1)
Skilled Stealth (1)
Shadow Blend (2)

Feat:
EWP (Falcata)

My intent with this build is to create a ghost-like, skills-focued eidolon that can still dish out some damage. I intend on taking Shadow Form later and still want to have "respectable" damage despite the net 50% less damage from being quasi-incorporeal. I know I won't be out damaging the fighter or barbarian, but, I would still like to contribute to the party DPR in a pinch.

The best way to do this, I think, is to specialize in a two-handing high crit weapon like the Falcata.

I plan on getting a keen Falcata about the same time I pick up Shadow Form. Will the 17-20x3 crit be enough to overcome the overall 50% damage?

Thanks,

You dont want shadow form! No amounts of crit bonus will make up for only doing 50% damage. Give it unnatural aura in stead. I also think you should consider getting a weapon a bit later. The claws are good at low levels. If you take combat reflexes or somthing at level 1 you can get a big axe or falchion or somthing at level 6 where you can also expect to have enlarge person on the Eidolon in most fights. But that is more personal preferance.

Shadow Form is only useful if your eidolon is a ranged attacker, since it only reduces melee damage dealt.
