A level 1 Swashbuckler can use Charisma instead of Intelligence when it comes to feat prereqs. At level 1, this Swashbuckler could take the Artful Dodge feat, which says "You can use Intelligence, rather than Dexterity, for feats with a minimum Dexterity prerequisite."
Can this swashbuckler, and his 19 Charisma, take Greater Two-Weapon Fighting, even if he only has 7 intelligence and 7 dex?
I don't see why this couldn't work legally. I'd probably disallow it at my table because it reeks of munchkinry. I am assuming a synthesis summoner or some such?
No. You can use Int for Dex feats and Chr for Int feats, but you don't have anything that lets you use Chr for Dex feats. Being able to use Int for a Dex prereq feat doesn't change the feat to an Int prereq feat.
"she can use her Charisma score in place of Intelligence as a prerequisite for combat feats."
"You can use Intelligence, rather than Dexterity, for feats with a minimum Dexterity prerequisite."
If they both had the same wording, I'd agree with you, Dave. "You can use Charisma, rather than Intelligence, for feats with a min INT prereq," but they don't have that wording.
Because then, you could argue that Greater Two-Weapon Fighting DOES NOT have an INT prereq.
And Leitner, it is munchkinry. Just theory-crafting a SAD Charisma build. Wouldn't be something I'd actually play. Though, I am curious if it's actually legal.
EDITED TO ADD: Just realized you mentioned Synth Summoner. I was under the impression that they'd be able to take the feats, but only be able to use them if their current DEX stat was high enough. I thought I remembered some FAQ, but that's neither here nor there.

No, he doesn't meet the BAB requirements.
Heh, ye. I meant, except for that. Does he qualify for DEX related feats using his CHA.
I was using that feat purely as example, not for the build.
If you were using that combo though, Nature Oracle gives CHA instead of DEX, but another 1 level dip into Scaled Fist Monk gives a class bonus to AC equal to CHA (effectively, but legally, giving CHA to your AC twice). But, since you lose armor, you're really only getting at most an extra 4 points of AC (+5 Mithril Fullplate gives +14 AC, compared to +10 CHA mod plus +8 bracers of Armor). Probably not worth the dip, unless you want a level of monk anyway. Or wanted your main class to be a gimped arcane Charisma caster.
If you wanted to keep with the silliness, dip two pally for saving throws.
I don't see this much SAD as being effective, though. Instead of burning feats and class levels on making everything CHA-based, you could just play a mildly MAD, better build.
Sometimes, makes me wish there were MMO "aggro" mechanics in PF, heh. Then super tanks would be good to play.
