Damage Reduction (Su)

An eidolon’s body becomes resistant to harm, granting it damage reduction. Choose one alignment: chaotic, evil, good, or lawful. The eidolon gains DR 5 that can be bypassed by weapons that possess the chosen alignment. The alignment must be opposite to one of the alignments possessed by the eidolon. At 12th level, this protection can be increased to DR 10 by spending 2 additional evolution points. The summoner must be at least 9th level before selecting this evolution.

An eidolon has the same alignment as the summoner that calls it

i'm putting together a neutral summoner for an upcoming game, and i was curious how a neutral summoner would use this evolution. since i have no opposed alignments, can i choose any of the above? would my eidolon's DR become untyped(ha!)?

As you don't have an opposite alignment your eidolon gains no benefit from this evolution. Just be happy that as a neutral summoner you can summon good and evil creatures to do your bidding.

It doesnt become untyped. It simply doesnt work.

Penalty for not taking a stance!

There are other benefits of neutrality, one of them pointed out in this thread. Being immune to the protection from good/evil/law/chaos line is another.

Just something to deal with

Here is a bit of information that might shed some light on things

"The purpose of the neutral (N) version of this item is to reserve the balance by defeating/slaying powerful beings of the extreme alignments (LG, LE, CG, CE)." - CRB page534

Personaly i would say that while you would be able to summon both good and evil the trade off would be that any of the extreams would bypass the DR. After all the oppsoite to neutral would be the extreams, wouldn't it?
