what is everyone using to determine "Weakness" or "ineffectiveness"?
Soulknife 20/ CW Samurai 20 .... IMHO, is actually a very strong, effective character .... it would not be compared to a Full Spellcaster, but it could be easily able to address most any CR 20 encounters it is faced with
strengths:
Full BAB
d10 HD
ALL Good saves
Kiai Smite
Bonus Feats:
Soulknife: Wildtalent(or Hidden Talent ACF and the ability to choose it more than once at higher levels), Weapon Focus(Mindblade),Speed of Thought, Greater Weapon Focus(Mindblade), Quickdraw(effectively for Mindblade)+ 5 more if you use Bonus Feats ACF
CW Samurai: TWF, ImpTWF, Greater TWF, Imp Initiative, Quickdraw
great Class Skills:
Autohypnosis* (Wis), Climb (Str), Concentration* (Con), Craft (Int), Diplomacy (Cha), Hide(Dex), Intimidate (Cha), Jump (Str), Knowledge (psionics)* (Int),Knowledge (history) (Int), Knowledge (nobility and royalty) (Int), Listen (Wis), Move Silently (Dex), Profession (Wis),Ride (Dex), Spot (Wis), Sense Motive (Wis), and Tumble (Dex).
you gain a Free +9 Katana that you can throw(also Bladewind+Kiai Smite = Ka-boom) + Intimidate Class features ...... thus you are free to spend the rest of your money on useful stuff, and have the rest of your feats to further boost your Martial Abilities .... Mage Slayer is a great focus for this type of build
i dont see the great Weakness or Ineffectiveness of this Build ... why is it considered so Bad?
