I have a character: Rogue 5 Red Mantis Assassin 5 Swashbuckler 1
Str 12 (+1) Dex 18 (+4)
Swashbuckler Finesse (all pointy things plus whatever)
Exotic Weapon Prof (Sawtooth Sabre)
Weapon Focus (sawtooth sabre) +1 to hit
Greater Weapon focus (sawtooth sabre - bonus) +1 to hit
Weapon Specialization (sawtooth sabre - bonus) +2 damage
Slashing Grace (sawtooth sabre) - counts as pointy things, and add Dex To Damage
longsword correct as +8/+3 (Str +1), 1D8+1 dam
rapier correct as +11/+6 (finesse, Dex +4), 1D6+1 dam
sawtooth sabre is not right... I see
+10/+5, dam 1d8+6
damage looks right: specialization +2, dex +4.
attack bonus should be, I calculate
+7 BAB, +4 Dex (slashing grace and swashbuckler finesse), +2 (weapon focus and greater WF) = +13
looks like it's lost the finesse boost? +7, Str +1, WF/GWF+2 = 10?
Exotic WP Sawtooth Sabre Sawtooth Sabre is "light" only for the purposes of 2WF, but it's a plain 1H slashing melee weapon otherwise. Slashing Grace then pulls it under Swashbuckler Finesse.
A swashbuckler gains the benefits of the Weapon Finesse feat with light or one-handed piercing melee weapons, and she can use her Charisma score in place of Intelligence as a prerequisite for combat feats. This ability counts as having the Weapon Finesse feat for purposes of meeting feat prerequisites.
"When wielding your Sawtooth Sabre one-handed, you can treat it as a one-handed piercing melee weapon for all feats and class abilities that require such a weapon and you can add your Dexterity modifier instead of your Strength modifier to that weapon's damage."
... is printed as a Conditional Modifier, which isn't very helpful with all the real interaction going on. In particular it's a struggle to spot that it is incomplete and lacking the conditional benefit when it's the single weapon used. (I had to add rapier and longsword to make sense of it!)
