Adapting the Alienist

[Vhaidara]

Okay, so, something I've wanted to do for a while is adapt the 3.5 Alienist into a Summoner PrC in Pathfinder.

So, there are some obvious things you need to do to make a Summoner PrC. Most importantly, it needs to advance the Eidolon. Ideally, it should advance the Eidolon at full rate, making sacrifices elsewhere in the class.

Does anyone have an opinion on what would be a fair trade for the PrC?

In my opinion, PF ALienist would fare better as an Archetype for the Summoner than a PrC. In fact, I have been lately working on such for my upcoming game. I'll post it when it's finished.
