Here is a synopsis of my master thrower. A halfling charisma-based thrower build:
Class (level) : Monk (1), Cleric (1), Fighter (4), Master Thrower (5), Exotic Weapon Master (1)
Net Level : 12
(no multiclass XP penalties are used in this campaign)
DEX = 20, CHA = 20 (+2 racial, +3 level-ups)
FEATS:
Char 1 : Exotic Weapon Proficiency (shuriken)
Char 3 : Point Blank Shot
Char 6 : Divine Might
Char 9 : Two-weapon Fighting
Char 12 : Improved Two-weapon Fighting
Monk 1 : Power Attack
Cleric 1 : Weapon Focus (shuriken) (from war domain)
Fighter 1 : Precise Shot
Fighter 2 : Rapid Shot
Fighter 4 : Weapon Specialization (shuriken)
Msr Thr 1 : Quick Draw
CLASS ABILITIES:
Monk 1 : Power Attack (overwhelming attack fighting style variant),
Flurry of Blows, Unarmed Strike
Cleric 1 : Domains (charm, war), Turn Undead
Fighter 1 : Bonus Feat
Fighter 2 : Bonus Feat
Fighter 4 : Bonus Feat
Master Thrower 1 : Quick Draw, Thrown Weapon Trick (palm throw)
Master Thrower 2 : Evasion
Master Thrower 3 : Thrown Weapon Trick (deadeye shot)
Master Thrower 4 : Snatch Arrows
Master Thrower 5 : Critical Throw, Thrown Weapon Trick (weak spot)
Exotic Weapon Master 1 : Exotic Weapon Stunt (close quarter ranged combat)
Shuriken (with Palm Throw, Flurry, Rapid Shot, Charm domain, Divine Might: +7 damage)
Attack : +14/+14/+14/+9/+4 & +14/+9 = 11/BAB, +5/dex, +1/size, +1/mw, +1/wf, +1/racial, -2/fob, -2/rs, -2/twf (1/point-blank, 1/higher ground)
(range increment is 10’, point blank within 30’)
Damage : 1+9 & 1+9 [19-20/x3] = -/str, +7/cha, +2/ws
This is usually 140 damage per round without magic items. Items improving dex and cha, plus the party cleric casting greater magic weapon on the shuriken could send the damage over 200 per round. All attacks are touch attacks, so it is fairly easy to hit most opponents.
