Here's my character concept:
A Bladebound Kensai Kitsune that uses a Scorpion Whip as it's Black Blade. With the Kensai Weapon Focus and the Kitsune alternate racial feature Natural Finesse, I'll be able to use Slashing Grace at level 1, and I'll get a +4 (from Dex of 19) to hit, damage, trip, and disarm with the Scorpion Whip, and I'll do all of that with a 15ft reach. I won't threaten with the Scorpion Whip until level 7, but I can use the Cestus to get AoO and help Flank (should I ever get into that unfortunate situation).
I was thinking I'll be CN, and was kicked out of my home due to a prank going to far and accidentally killing people. And I was given a LN Intelligent Scorpion Whip for the purpose of leading me to my redemption (my GM will allow it to be intelligent at level 1 if I don't treat it as magical or MW, since it makes good story, and he'll allow it to be a different alignment than my character even though the Black Blade is supposed to be the same alignment).
Stats (20 Point buy, Kitsune gets -2 Str, +2 Dex, +2 Cha):
5 Str (7 - 2)
19 Dex (17 + 2)
12 Con
17 Int
8 Wis
10 Cha (8 + 2)
I was originally going to make a Bladed Scarf Dancer, but I've since decided to go with a Kensai that acts as a Scarf Dancer (and considers his Scorpion Whip to be a Bladed Scarf).
Additional Equipment on Body
Haramaki
Pickpocket's Outfit
Pocketed Scarf (I can't help myself from stealing things).
Spell Component Pouch
All those items along with the Scorpion Whip, Cestus, and Buckler will weigh a total of 15.5 lbs, and the Carrying Capacity is 16 lbs.
I'm thinking I can carry my rations, water, Spellbook and a couple other items in a Sack and I can drop the sack whenever battle starts, assuming I'm in a cave or somewhere else that I can't use my horse for carrying things.
Here's my character progression (I'll be starting at level 1 and ending whenever I die):
1: Arcane Pool, Cantrips, Spell Combat, Canny Defense, Weapon Focus (Scorpion Whip), Natural Finesse (racial trait), Slashing Grace(Scorpion Whip)
2: Spellstrike
3: Black Blade, Whip Mastery
4: +1 Dex, Perfect Strike
5: Bonus feat (Weapon Versatility, lets my Whip do S, P, or B damage as needed), Impersonate (because I'm a prankster Kitsune)
6: Magus arcana(UMD Familiar, or maybe Wand Wielder?)
7: Fighter Training, Iaijutsu, Improved Whip Mastery
8: +1 Int, Improved spell combat
9: Critical Perfection, Fox Shape (all the better to steal with and gather intel, and assuming I have a Headband with +4 Cha)
10: Fighter training
11: Bonus feat (Greater Whip Mastery so I don't drop my whip), Superior Reflexes, Odd Level Feat (Extra Arcana, I should be able to convince my GM to let me use Spirit Fingers from the Scarf Dancer Archetype, since the Whip is flexible like a scarf).
With a Buckler, I'll have an AC of 17 at level 1, and the AC will increase by 1 for every level due to Canny Defense (Max of my Int mod). I know I'll have the 5% spell failure until I can get a Mithal Buckler, and I won't get the Shield AC when casting with Spell Combat, but as I'll have Diminished Spell Casting, so I won't be casting as much as I could.
Overall I'm going for a character that can control the field and act as a debuffer, with a secondary purpose of dealing damage (really depends on the situation). I think I need to skip on Improved Trip and Disarm, as I can't really afford the at the early levels (due to all of the Whip feats). I also think Maneuver Mastery isn't worth it, since the Magus is already at 2/3 Bab growth, and the arcana only works for one maneuver.
I think this character will be pretty powerful, even if he does have a few quirks, such as not being able to lift anything and constantly arguing with his weapon. I just want to make sure that this will work out, and that there isn't anything I'm overlooking, such as the Cestus getting in the way of Spell Combat or Slashing Grace, or maybe the Scorpion Whip isn't as good as I think (since reading between all of the forums on that weapon is a bit confusing), or for other reasons.
Thanks for any input and sorry for the TLDR,
