Both series are awesome. I'm actually thinking of making a character like Syrio Forel (at least like the man we know him to be so far, we may learn more of him later). Basically what I want is an unarmored master swordsman. Looking at the classes this is what I came up with:
Monk 1
Figher 1-4
Monk 2
Ranger 1
Ninja of the Crescent Moon 1-3
Duelist 1-10
You end up with 19 BAB, and can apply your dex, int, and wisdom to AC. Let me justify a couple choices - ranger is so that you can make offhand attacks with your bare hand (thanks to monk levels) or as a kick or whatever. Ninja of the Crescent Moon kind of gives that mysterious background feel, like "I was a member of the Braavos" and also it's pretty much just plain better than 3 levels of fighter at this point (loss of 1 feat for 2d6 sneak attack, +3 to all saves, and improved evasion). And the prerequisites are easy, except for Quickdraw, which fits in with the character concept anyway.
The skill ranks required for ninja of the crescent moon are really tight, but doable for a human with 12 intelligence (that gives you 4 skillpoints per level as a fighter, which you can turn into +1 hide and move silently each level)
Feats: Improved Unarmed Strike*, Deflect Arrows*, Ambidexterity*, Two Weapon Fighting*, Track*, Weapon Focus: Rapier, Weapon Specialization: Rapier, Quickdraw, Dodge, Mobility, Spring Attack, Weapon Finesse: Rapier, Power Attack, Improved Initiative.. and two more of one flavor or another. (* denotes free feats)
Special Abilities: +2d6 sneak attack, evasion, improved evasion, +3d6 precise strike, assorted other stuff.
The only thing I really wish I could give the character is the first two levels of uncanny dodge. Unfortunately that's a real b*tch to get. You need 6 levels of rogue to do it (or 5 of barbarian (why do they get it earlier?) but that doesn't even come close to fitting the character concept), which means you're sucking up two levels of +0 BAB. Add in the monk level and that's 3.
Any thoughts? Any suggestions on how to make this guy better? He's pretty well min/maxed right now, but perhaps someone knows something to make him even moreso.
