Reanimated Medium / Spirit Summoner (Brainstorming / Advice)

[DeathlessOne]

So, first thing to get out of the way ... I know this is not optimal and I don't particularly care. I'm just running with a character concept that I had in mind and exploring its potential. I want to take the concept, expand on it, see what others think about the flavor, and then start trimming the excess off.

Anyway, the concept is thus:

Spoiler:

A young (insert race: half elf?) experiences a fairly close encounter with death. So close, in fact, that most of his soul leaves his body and travels to the Boneyard for judgement. This leaves what little is left of his soul in place to run the mechanical aspects of his body and barely registers on the conscious level. Some lingering spirits sense this almost "empty vessel" and choose to inhabit the body, some at different times as even a partial soul resists possession over a period of time. The character earns a well deserved reputation for being erratic and hard to predict. Starting level: Medium

This drives the character towards a life of adventuring. Despite all his erratic and unpredictable behavior, the character is still good at heart and seeks to right wrongs, especially the ones that effected his possessing spirits. Eventually, the character learns that he is the way he is because of his divided soul, and then seeks to reunite the pieces. Or rather, the possessing spirits make that decision for the body, as sort of a payment for using his body and for services rendered. Que level: Summoner

During all this time, his soul has passed into the afterlife and made the transformation into an outsider, emerging as a Bipedal Agathion in service of Sarenrae. Not long after, it feels the call of a summoner to bargain for service. This call could easily be ignored, but something was familiar about the call and it was eager to prove itself in the service of its deity. It answered the call, only to be placed face-to-face with itself even though it's mortal body should be long dead and returned to the soil. Seeking to right this wrong, and feeling extremely responsible for the life lead so far by the shell of a mortal, it became an Eidolon of the summoner. It was only a mortal-long life of service, after all.

Once the connection was made, the Eidolon ceased to be separate creature from the summoner, immediately finding itself fully in control of the mortal, the small fragment of its original soul welcoming its return and offering up control. The soul fragment could not rejoin it, as it was made of different energy now, but the relief was still palpable. The Eidolon, so long freed from mortal flesh, could hardly stand the feeling of claustrophobia, was able to eject itself from the body using the typical summoner' call, leaving the mortal flesh once more open to occupancy by a local spirit.

Thus, when Eidolon is summoned, the body houses one of the medium's spirit's, leaving the Eidolon as the "playable character". When the Eidolon is banished or sent back to its home plane, it merely returns to its mortal body, unable to emerge until it heals.

So, if you managed to get through that summary, let's get to the mechanics.

Point buy: (15)
Race: Half-elf (though I am open for changes, mostly wanted the evolution points)
Reanimated Medium 1 (maybe max of 4 levels)
Spirit Summoner 19 (16 if GM allows Boon Comapnion to work)
Eidolon subtype: Agathion
Bipedal form (maybe quadruped... Maybe)

I am trying to pin down the best way to tackle combat with the two. The Eidolon is definitely going to be a Melee combatant, natural weapons. The summoner is going to buff and maybe used ranged weapons, though will have access to hexes, so ... might gear towards a switch hitter.

Anyway, that's where I am at the point. What do you think would make this combination more interesting (without cutting anything away at this point)?

[DeathlessOne]

... Okay. Generated almost no interest, I see. Oh, well. I've had more time to think on this and will post what I've found.

I've determined that I will use the VMC option for Paladin. Since I will mostly be using the summoner for buffing (between spells and hexes), not much room (or time) will be spent attacking and I don't plan on wasting resources towards those ends. Lay on Hands (and on both summoner and eidolon) will be highly useful, and smite evil can be used (to great effect) if the summoner ever does get pinned in melee.

Summoner will be taking the Life Spirit for channel energy and life-link options, and use feats to qualify for Eldtritch Heritage in order to acquire a familiar (protector). The swift action option later for channeling will be good. In addition, the spells made available to him from the spirit help the rest of the party. After 5th level, I still have not chosen the rest of the summoner' feats (all four of them). Depends if I need more extra hexes or extra evolutions.

We will most likely need to spend a good portion of the wealth on an amulet of mighty fist for the eidolon.

The biggest question I am still torn between is between a quadruped or biped form for the eidolon. Sarenrae does not have any particular animals associated with her (that I could find) so, I looked to other resources. Neutral Good is associated with Nirvana (outer plane) and Agathions are from there, sharing many bestial aspects. Some almost fully beasts, others more of a hybrid form. The Leonal matches pretty close to what I had in mind (even has lay on hands). Let's try to model that Agathion. Flavor over function.

Evolutions (in no particular order):
Bite (1)
Damage Reduction Increase (3)
Frightful Presence (3) [To simulate Roar, not very well though]
Grab (Bite) (2)
Claws (free)
Pounce (3)
Rake (2)
Scent (1)
Spell Resistance (4)

So, that's 19 points to spend. We'll get +4 from FCB and 15 from normal progression. Entirely do-able.
