Question about Champions of Purity summons list

Are players allowed to use the summons list from the back of champions of purity without having the feat? As the rules say in the additional resources it seems like you would be able to without the feat just with it you can summon them with Diehard. Anyone know the exact ruling on this?

The feat states that you must have it in order to access the summon list.

I have to agree with doc though that it is very unclear. When I read the additional resources, I end up with the same conclusion. That the summons are all "legal" and with the feat they get Diehard.

I agree with Nani on the intention of the AR though.

Yeah I hope it get's cleared up quickly. Either way I plan to take the feat with the character I'm designing it would just be nice to know if I can drop foo dogs and other fun creatures a little earlier.

Just as a heads up, this was clarified in the AR.
