Summoner Eidolon Help

[Scrynor]

I'm interested in starting making a summoner and I've seen some threads that say, "Summoners are OP" with immediate responses of "Most OP builds have been revealed to have illegal eidelon builds".

Could provide me a quick guide to what the common illegal pitfalls are or point me to such a guide so I can make sure I don't screw everything up?

Read that guide.

Get intimate with how the monster rules work, especially natural attacks.

Just follow the rules as written.

Make sure you have your prereqs taken care of for every evolution you take.

Make sure your points add up.

The above is where most mistakes happen.

Thanks.
