Edit: I do have another question. Does the natural weapon effective size increase from Improved Natural Attack stack with the natural weapon effective size increases from Frostrager? I'm guessing no just to keep things from getting too crazy.
Yes, up to Colossal, but if your worried about it being too crazy then don't do it?
Sor0, do you mind if I change my build to an Old Human (just a place-holder until I settle on a more appropriate race) Expert 1/Ranger 1/Monk (Stately Ancient Sifu ACF) 3/Unrepentant Pact-Bound Hunter 10/X 5 (curse you persistently blank final levels!)
A. That entire thing is a little High++ Op isn't it? Ignore Stunning immunity, infinite Stun usage? Hey why not give auto-spell-channeling attacks to go with the infinite spell casting, and extra damage on top of that, and heck extra Invocations for like two Feats while you're at it for like two Feats? Oh... You did.
B. Was actually wondering about Stunning Fist's cap being reduced and revamped into a self regenerating trait. Only reason I didn't was because it's comparable to Bardic Music (both 1/day/level) and *shudders* Metamagic Song would be insane.
So that being said, I suppose I could offer up an alternative. 1+(lvl/4) Stuns per encounter and Ascetic Mage accepts the Warlock's Invocations. It wouldn't be anything like dumping NI Stuns from an infinite pool into extra Wis-To-Attack/Damage & Stun-Immunity-Bypassing-Stun & Fiery Fist's Damage & +3d6 Damage & an entire Invocation & God-Knows-What-Else per hit in a Furry of Blows multiple attack action with the strongest Weapon in D&D, but you'd kind of sort of have infinite Stuns per day for Ki stuff and the ability to augment your Monkyness with Warlock.

Also,
only level 1 has any NPC levels. It's a skill/social based very low combat time period simultaneously giving you a way to act out in character if the other timelines are not delivering your favorite level of RP and lets face it you'll be trying using this split up time line to your advantage anyway.
lv15-NPC: What do you know about Karse?
lv1-You: Daddy, whose is that man dressed up like that over there?
Daddy: Oh, some merchant from Karse.
lv1-You: Really, what do you know about it?
lv4-You: *to the librarian* I'm studying Geography, got any maps of say, different countries?
lv9-You: Job well done, vacation time. I heard Karse is pretty cool this time of year.
lv15-You: Everything.So hopefully it'll be the thread most of that effort is channeled into as you in fact you have a form of permission to use your level 1 snapshot exactly like that. Only arc planned for it amounts to an introduction to a later timeline will have to deal with anyway, rest is just winging it.
