This build is a late bloomer and very very hard to play from level 1 upwards.
It get's a bit easier in Mask of the Betrayer, but still, the critical levels where feats become available that make the Kaze rule the battlefield start at 21.
However, if you manage to survive up till then and equip your character with good gear (the build is heavily gear dependent), then you will get the strongest melee build you'll ever see.
Assuming a level 30 character fully equiped with items you'll either find in the game or be able to create, you'll end up with these combat values:
The elemental damage comes from self enchanted kamas+8.Main Hand Attack Bonus: +55/+55/+50/+50/+45/+40/+35/+30/+25/+20
Damage: 1-6 +12 +8(slashing) +5d6(fire) +5d6(cold) +5d6(lightning)
Off Hand Attack Bonus: +50/+45/+40/+35/+30/+25/+20/+15
Damage: 1-6 +9 +8(slashing) +5d6(fire) +5d6(cold) +5d6(lightning)
AC: 74
HP: 438
Fortitude: 29
Reflex: 31
Will: 25
And yes, that's 18 attacks per round, starting with AB 55.
The AC 74 is no typo either.
And don't forget the extremely high saves.
The character is - apart from a haste spell - unbuffed.
The equipment however includes items that give +8 attribute points to at least DEX/WIS/INT.
The idea behind the build is this: Maximize the bonuses you can get from attribute bonuses.
DEX improves attack bonus (weapon finesse) and AC for every 2 points.
WIS improves AC (monk) and saves.
INT improves AC and damage (Unfettered Defense,combat insight)
CON improves HP (no surprise there).
STR improves the amount of stuff you can carry (and nothing else)
CHA only social value, unless you take a drow with paladin levels instead of divine champion. in that case, CHA improves saves.
You start out with
STR 6
DEX 18
CON 14
INT 14
WIS 18
CHA 4
and continually raise DEX to 26. Here you can see why playing the Kaze from the start is rather hard: STR 6
STR won't matter later, once you pick combat insight, but before that, battles will be hard unless you get some elemental damage kamas.
Monk 11 will give you greater flurry, Fighter 12 gives access to epic weapon focus and epic weapon specialization.
Invisible Blade gets you an additional AC+5 and divine champion +1 to saves and an extra feat.
So, if you want to ever get the feeling that you could really take on a certain god and win, then this is the character for you.
If get's to level 30 well before the end, despite the ECL 3, so no worries.
Cheers !
