Thomas Hobbes: I think death touch may be a wee bit overpowered. Think about it. 6th level priest does 6d6 or on average 21. Now since hp don't progress, and there isn't a save for that ability, that means that in two levels you have a kill attack 1/day. Yikes.
Okay, here he is, edited for cost and with a few misc comments.
I'll probably go for 2 levels of fighter/expert followed actually by a level of assasin/warrior, then I'll wing it from there.
Since I realized that I don't need finesse (due to GnG), I think I might switch weapons to a spear or a longspear. Would you allow a feat to "choke up" on a longspear (use it as a non-reach weapon)? Using a different weapon would be beneficial for two reasons: firstly I'm different

, and second less likely to be regulated (swords are supposed to be mainly samurai weapons). I haven't decided yet, but I'm leaning towards spear. If I do, I'll switch out my proficiency for either a weapon focus feat or a feat to "choke up". Spear will rule out duelist, and so I'll just go straight assasin. What are your opinions?

Appearence: Rokuro is a thin, almost gaunt man with reddish eyes and black hair. His skin is slightly dark, and he gives the appearence of always being shadowed. Some people have intimated that he had a member of the Horde somewhere in his ancestory (and well he might, as he doesn't know his father). Few people have intimated this twice, as it's hard to speak with punctured lungs. He wears a chain shirt stained pure black with a stylized red sun with a spear through it in the center. He carries a thin sword (or a spear, haven't decided yet), the blade (or head) of which usually glistens black from some nameless substance (usually Sassone Leaf Residue).
Personality: Rokuro is a reclusive man, who speaks little. He is tightly controlled, and gives little away by his movements. While being vicious and often cruel in battle, Rokuro is not particularly evil. He will neither go out of his way to harm people or to help them. Rokuro does have a love of battle, and will seek out work fighting or even simply go hunt down something to fight. His greatest delight is to face an equal opponent in combat, although he will not shrink from killing those less skilled than he (although he looks down on the slaughter of the helpless).
History: Rokuro was the bastard son of a noble house of the Middle Kingdom, left to the care of an adoptive father who cared little for him. Thrown out at the age of ten to live or die in the streets when his true mother died (and thus stopped paying his adoptive father to keep him), he survived through a combination of cunning, agility, and shear animal ferocity. For a while he lived
as a pickpocket in the city, until he tried to pick the pocket of a member of the Serpent Clan. Fortunately for him, rather than being outraged and killing him at once, the man was amused. Angry at this apparent mockery, Rokuro drew a knife and attacked the man. Within a second, he was flat on his back with his entire are numb from the wrench with which he had been disarmed. To his amazement, rather than gutting him, the man bent over and offered him a hand up. Warily, Rokuro asked what the man meant by this, and he said that he saw skill in Rokuro, and would offer him training and a home if he wished. Rokuro accepted, and his life changed. From that point on Rokuro trained rigorously as first a warrior, then a wrathful one of the serpent clan. At the age of 20, Rokuro was a skilled member of the clan, and once again his life changed, this time for the worse. While in the city, he was bumped into by a drunken nobleman who took offence at the "wretch who dared touch me." Caught with no way to avoid a duel, Rokuro was forced to fight. He and the noble took wounds, and the duel ended. Rokuro recovered, the noble didn't. Rokuro was banished from the kingdom under suspicion of having used poison in a duel, and came thus to the Kingdom of Harmony. He has only been here for a few months, working as a paid mercenary.
Okay, for the name, I thought that the middle kingdom was japanese-ish as well. Whoops. Could you just quickly tell me what the middle kingdom is like? I'll change the name probably if it isn't japanese. New name probably Oberyn Martell, Red Viper of Dorne.
For the poison craft rules. I don't know. I've always thought those times were a little off. Let's take a 10th level expert with int 18 and skill focus (craft

oisonmaking). He has +20 to his craft check. Now lets take Sassone leaf residue, which is supposed to be a relatively common poison. It costs 3000 sp, dc 15 to make. Now suppose he takes 10. In one week he makes (30*15) sp or 450 sp of poison. At this rate it will take him almost 7 weeks to make one dose of relatively common poison. And that's at 10th level geared specifically to make poison. That seems a little off.
Anyways, you can rule that any way you want, that's just my little rant.
