If you have a Kensai that is using the two Weapon fighting route.
Can he make more then one signature Weapon?
The class doesnt prohibit it but it doesnt say so explicit.
Therefore whats your opinion?
The text does state "a signature weapon" without any indication of plurality. The term "signature" tends to identify one weapon for which the kensai is renowned for; Arthur & Excaliber, Jedi & their light sabers (they get bonus' for using the weapon they crafted), etc...
I would not allow the kensai to create two signature weapons. The xp cost is a pretty good deterrent, but by 15th level, the character could potentially have two +10 weapons...
And, purchasing a complementary weapon would not be that difficult. Especially when he's paying nothing (in gold) for his primary weapon.
"The kensai chooses one of his weapons to become a signature weapon."
One weapon. Not two. If you wanted to, you could use the double weapon rules, but I would be wary, as two weapons have far more flexibility than one double weapon.
for the answers. That clarfies the PrC.
Was thinking about combining a Priest of a War good with the PrC.
Would mean taking 7 Cleric Levels and then going down the Kensai route alternating with Cl levels.
What do you think, about this build idea?
* Other classes that can qualify for Kensai in 5 levels: Samurai (OA or CompWar), Hexblade (CompWar, LN or LE), Soulborn (MoI, LG only), and the Crusader (Bo9S)
