A sample character who maxes out CHA.
Off the top of my head, she gets 67 AC, +21 to all saving throws, insane spell DCs, uses CHA for concentration checks, dexterity checks (including initiative) and pretty much a host of other things.
Dude, you don't have to put your URLs in quotes.
Also, I'm curious as to how a half-fey qualities for half-vampire, since I don't think the template can be applied to fey type creatures.
Anyway, as previously mentioned, things like
Ghost2/Battledancer 1/ Hexblade 3/Cloistered Cleric 3/ Prestige Paladin (of freedom) 2/ Mystic Wanderer 1.
With divine shield, and "channel positive energy: Fate's mercy" (KoKPG). Can add cha to AC four times, cha to saves four times, and your cha to your allies' saves once.
IIRC, there's a first level pally divination buff that gives your cha bonus to a single save as well, which can be used on allies.
