Eidolon evolution questions, Heads and Bites and Breath Attacks? Ability Increases?

[Merellin]

So, I was curious, With the Summoners Eidolon if I wanted to make a three headed dog, Could I give all three heads bite attacks?

Also, The Quadruped dosent get a Head as a free evolution but does get a Bite, Does this mean i'd have to buy 2 heads to get a seocnd bite or just one?, Will I have to buy a total of 2 heads or a total of 3 heads to have a dog with 3 heads and 3 bite attacks?

And can I have both a Bite and a Breath Attack on the same head, Or would they need to be on diferent heads?

Thanks in advance!

Edit: Oh yeah! With the Ability Increase evolution, It says "This evolution can be selected more than once. It can only be applied once to an individual ability score, plus 1 additional time for every 6 levels the summoner possesses." Does this mean it can be taken multiple times, But only once per 6 levels, And can only effect each score once? Or does it mean it can be taken multiple times, But can only apply to the same score once per 6 levels? I'm gessing the first one.

RAW, no. "Unless otherwise noted, each evolution can only be selected once"; and the bite evolution does not say otherwise.

However, Ultimate Magic gave a bunch of "Eidolon models", which are "pre-built examples", with the hydra having four additional heads with a bite each. Not something that'd help in PFS, but it's a good ground the ask the GM on.

We're far out of RAW waters at this point, so we have to go by common sense anyway. The bite evolution does not demand the head evolution, because without it being selectable multiple times, it doesn't need to. Every eidolon starts with a head, so presuming your GM allows the whole thing, you need to select the head and bite evolutions twice each. As a GM, I'd either ban the other use of the bite evolution (1.5xStr), or say each additional selection of the evolution applies only to one existing bite attack; even the latter would be very powerful.

"Breath Weapon" does not have any prereq-evolutions. Breath weapons may be called that, but they aren't weapons, but rather supernatural abilities, so they don't in any way interfere with existing natural weapons.

The selection and application are dealt with in seperate sentences, with the 1/6 levels thing appearing in the latter's. There is no overall limit on how often you can select the evolution, meaning a 6th level Eidolon could have it 12 times.

Thank you! Very helpful post!

An eidolon grows an additional head. The eidolon does not gain any additional natural attacks for the additional head, but the additional head does allow the eidolon to take other evolutions that add an additional attack to a head (such as a bite, gore, or breath weapon). This evolution can be selected more than once.

Seems like a pretty clear delimit on the number of times you can take things to me. It's probably designed this way since the first(default) head isn't considered it's own evolution (otherwise an eidolon could "survive without its head" probably, or at least cause questions of the like).
