Question for AC Bonus stacking (3.PF)

[Thump]

I plan to have a character at level 30 gestalt with the ideal of being virtually untouchable, and I got an idea after seeing a homebrew by one of the guys in the forum.

Nymph(3.5e) with 20 levels of Sepulcher Knight (archetype for Antipaladin from PF) on one side. and 16 LA of Evolved Undead to pump Charisma to absurd levels for the deflection bonus to rise to 30-ish on its own. Take a level of Ninja (3.5e) and take Ascetic Mage to get CHA instead of Wis to AC. Take one level of Oracle for the Lore mystery plus the revelation that replaces Dex with CHA to AC... throw in some other stuff, reach an AC of 125, and a touch AC of 109.

Is this even legal? It seems a bit absurd.

Technically, yes, although applying Evolved Undead that many times means your character will have been in existence for a bare minimum of 1600 (plus however long it took to get 20 levels in Knight of the Sepulcher to become Undead to start) years and likely more in the area of 3,000. Which a theoretical DM might not be comfortable with (although if you do get to do it, I suggest having fun with giving "you kids today/in MY day..." style speeches to absolutely everybody who isn't at least two thousand years old.) Aside from the Evolved Undead bit you're just doing a regular Charisma stack, which is a pretty well recognized and formalized optimization tech.

[Thump]

Well, fey are immortal, so I suppose it doesn't matter for the amount of time that he's in existence; I pinned it around 13,000 years, just because by fluff it was accelerated multiple times (read, still took a hell of a lot of time) by mass exposure to negative energies.

I will enjoy being able to tell dragons what it was like back in the day, though.

May or may not be.

How untouchable do you want to be? There's ways to literally get the Invulnerability special quality using only WotC sources, or to be immune to attack from everything except a creature that exists solely in your own imagination... although keeping that completely undispellable is harder.

As to the age:

1% per century, cumulative for the number of instances of Evolved Undead already on there. So we make a table:
{table=head]Evolved Levels | Expected years since last | total age
1|10000|10000
2|5000|15000
3|3333.33333333333|18333.3333333333

[/table]

Note: That's just taking the "average" for each stage change and adding them up. The actual average age will vary quite a bit based on cumulative change. An undead that advances in the first century now has an average of 5,000 years to get the second, independently of the first now that the first has happened.

Oh, and go with Gloura (underdark), not Nymph. Allows you to play either gender, gives you wings, has lower LA, and the racial casting permits you to easily (one level dip into Bard) qualify for Sublime Chord, which gets you your 9th level Arcane casting... based on Charisma.

Since I don't want to go too overboard, I just want to be mostly untouchable versus melee, touch attacks and saves. (Saves are all 100+). I'm also going with Nymph because of the setting we're in, and for the backstory. Basically, she was the equivalent of an outcast, and went to live in a city full of elves. Unfortunately, she looked enough like an elf that when a bunch of elf-hating demons came along, she barely survived with her life, and was touched by the evil, leading her along the path to undeath. Later interactions with artifacts of evil lead to her evolution accelerating, and so on.

Attacks are pretty beastly, considering with the amount of Strength given by the template and the items I can get, it makes me pretty much a better fighter than any other race that isn't also an evolved undead. From checking, there's pretty much nothing in the Pathfinder SRD that I can't hit on an 8 or higher, and nothing on the d20 SRD that I can't hit. Combined with an array of spells (plus a stupid number of bonus spells), I can pretty much afford to not have 9th level casting in exchange for being pretty much invulnerable (1,155 HP plus untouchable AC/saves?).

And... what do you do when someone who focused on action economy abuse tosses 20+ Save-or-X spells at you every round (Wizard-30//Factotum-30 spending lots of feats on Font of Inspiration, and taking all Epic feats as Multispell)? Command Undead makes for a great choice for this target.

Also: Are Epic spells in play? If so, numbers stop mattering pretty quickly.

Cannot physically fail the saves (except Reflex saves, and only on a one.). Can't fail Will saves on a one, immune to anything that needs a Fortitude save, and HP just sucks up anything with a Reflex save that I roll a one on.

Epic spells aren't in play.
