So I have a PC with a pretty rich level 6 Summoner, who bought decided to buy a few permanency spells to make his Eidolon really strong, by buffing it's natural attacks. Is it best to try to get as many natural attacks with as much damage as possible, and it seems to work pretty well. I was wondering if there is a really good build out there for eidolons. He has the following evolutions: Flight, Bite (2d6+1d6+1d6+6), Bleed (Bite), Tail, Improved Damagex2 (Bite and Tail), Energy Attacks (Cold), Wing Buffet(1d6+1d6+3), Tail Slap (2d6+1d6+3). He has the Improved Natural Attacks feats for the wings and the bite, and the multiattack feat. What should he do in the future to improve this? What evolutions should he take? I like to have my PCs make the most out of their characters.

Note: He took a few Extra Evolution feats so he can upgrade the eidolon more, as well as the Augment Summoning feat.

So I'm a GM, a newer one at that, I played D&D a lot a few years ago and GM'd a few times here and there, and I'm just getting back into it. I play with a small group of friends, and I was wondering about what I should do to make the campaign a little fair, seeing as it's on two PCs at the moment. I have made several characters to help them, but I was wondering what the specific term for PC would be...like is all the character played by people who aren't me (The GM) PCs? And all those I control are NPCs?
Another thing is that since there is so few of them, it is quite hard for them sometimes (Skulls and Shackles). Should I make some of the characters I've made just become part of their party by role playing it out, or should I adjust the creatures so they aren't as powerful, like throwing a CR 6 at a couple of level 3 and 4s seems a bit overwhelming.

Okay, I need someone to explain how to add BAB when multiclassing to me. A level 16 fighter's BAB is +16/+11/+6/+1, and a level four cleric's BAB is +3. To which number is the +3 added to?

I'm attempting to make a bite attack really powerful for my character, so far, I have the Improve Natural Attack Feat and the Cloak of Fangs to improve it, anything else to make it better?

If you take the Evolved Familiar feat multiple times, would that allow you to pick a higher evolution? Like if I took the feat three times, could I take a three point evolution?

Would casting a Permanency Spell on a Bestow Weapon Proficiency Spell work?
