Is it just me (and I've misread or fumbled my maths) or is the title combo really good at disguises?
e.g. The kitsune changes to a specific human form (kitsune change shape ability +10 racial bonus, and realistic likeness +10 circumstance bonus) and then drinks the disguise self extract (+10 bonus to disguise, illusion-based), for a total of 1d20+36 (the above plus 1 rank, class still and +2 ability mod) minus any gender/size/age/etc change (note they are reduced due to infiltrator) at level 1.
And at 4th, replace the disguise self for alter self (no longer illusion, and now add the 2nd level infiltrator ability mimic mastery to add a further +10 bonus for a specific idv. total +20 from alter self) bringing it to 1d20+49 (increased ranks to 4).
Can also add inspiration, get a disguise kit, or other mundane items to increase it.
Most of the insane bonuses will be negated by true seeing (in fact all the +10's will be negated being magical in nature), but that's basically an 11th level caster
This is PFS legal.
Is this the ultimate spy? The being able to walk into any room through the front door (need a good bluff mod, you "are" the boss) as the owner?
