Hi there InEffect, I'm a big fan of your work.
I'm curious what you'd think of this build for a tank:
Angelkin Aasimar (+Str, +Cha, wings option)
Sorcerer 1 (to open up dragon disciple)
Monk 1 (Scaled fist, adds CHA to AC, plus crane style)
Paladin 2 (Divine Hunter because why not, CHA to saves)
Sword Saint 1 (Building with Longswords to take advantage of the Perfection longsword later on)
Dragon Disciple 4 (adds STR, gives us bonus natural armor that stacks with natural armor necklaces)
Sword Saint everything else (what's really important here is it helps us by adding Int to AC as a Dodge bonus, which stacks)
With the master artisan's potion and the +8 hat, I think you could get +9 of Canny Defense AC out of this, PLUS the Natural armor boost from the Dragon Disciple, making this MC a good tank (Plus, he's a monk, plus the CHA to AC, etc.)
The boosted STR from Dragon Disciple makes them decent in combat as well. Bonus to saves from CHA makes this character pass the vast majority of saving throws in late game as well.
The drawback of course is that this is a MAD build, requiring STR, CHA, INT (and Dex never hurts either)
tl;dr - I think I have a build that combines really good AC with really good saves and some decent combat power.
why sorc? go with 2 levels of archaeologist instead. uncanny dodge and a feat and DD access, If you want sense vitals you gotta go a lot deeper into sorc to get any benefits
monk. no objections.
Paladin - why? you are already dipping everywhere. If you want those saves make any cleric cast Bestow Grace of the Champion on you.
4DD good. 3AC and 4 str.
Sword Saint. sure, why not. 9 or 11 levels of that are good. so SS11/archaeologist 2/M1/DD4/vivisectionist1 or something along the lines.
