[Phillip Gastone]

So I saw this. and wonder if anyone has ideas on how to stat this up for PF1? :)

Summoner with an Ancestor Eidolon and say an improved familiar that can take the form of a humanoid (sort of Cassian Angel, Tripurasura) or constantly cast and share Alter Self spell with it.

I see it as a subtype of infiltrator.
With a hat of disguise and add shared items class feature and you can have an awesome spy.
