忍者能这么做么？

[涅薇儿·德拉诺尔]

忍者有个忍术是：
忍法 - 血裂*（Bleeding Attack，Ex）：拥有此忍术的忍者可以通过偷袭让活体目标流血。流血攻击令目标受到每偷袭伤害骰1点伤害。流血的生物在每轮行动开始时都会受到流血伤害。流血可被DC15的医疗检定，或其他任何恢复生命值的效果终止。此能力造成的流血伤害不与其自身叠加。流血伤害无视该生物的伤害减免。
这个究竟是在正常偷袭的基础上加上每轮5点流血伤害，还是当次攻击没有偷袭骰的伤害？

然后有个专长是
闷棍师（Sap Master）［战斗］
　　你在最恰当的时点敲中对手的七寸。
　　先决条件：偷袭+3d6，闷棍手。
　　专长效果：当你使用钝击武器、对一个措手不及的对象造成非致命伤害的偷袭时，将所有偷袭d6双骰合计作为非致命偷袭伤害。

这个专长能与上面的专长搭配，让每轮出血的数值翻倍吗？

闷棍手（Sap Adept）［战斗］
　　你了解如何打到敌人的痛处。
　　先决条件：偷袭+1d6。
　　专长效果：当你使用钝击武器造成非致命伤害的偷袭时，伤害检定获得两倍于偷袭d6骰数的加值（譬如，偷袭+5d6则在专长发动后追加10点伤害）。

以及，这个闷棍师专长的前置是否会因为闷棍师专长追加的瘀伤偷袭骰而增加额外的伤害检定加值？

Bleeding Attack: 不清楚，不過 PF 的同名能力的原文很接近，只多了"額外流血傷害"的額外二字。

Sap Master: 不能。雙骰估計是指 roll twice，而不是在規則上多加一倍偷襲骰。

Sap Adept: 同上。

那么……这两个瘀伤偷袭加倍的效果，是否能作用在远程的瘀伤钝击武器上？

[Lomias]

Bleeding Attack* (Ex): A ninja with this trick can cause living opponents to bleed by hitting them with a sneak attack. This attack causes the target to take 1 additional point of damage each round for each die of the ninja’s sneak attack. Bleeding creatures take that amount of damage every round at the start of each of their turns. The bleeding can be stopped by a DC 15 Heal check or the application of any effect that heals hit point damage. Bleed damage from this ability does not stack with itself. Bleed damage bypasses any DR the creature might possess.

呃...雖然沒有明文說不可以, 不過打瘀傷還能打出血這個有點難以想像呢

當然可以, 遠程偷襲限制不少就是了

the initial question was basically this i manage to take those 3 feats:Knockout Artist,Sap Adept (Combat),Sap Master (Combat). Let's assume i did so as soon as possible so i'm a level 5 rogue/ninja and have a Sneak attack 3d6.
so let's assume  manage to sneak on someone and try to knock him out with a punch. as i read those feats i'd say i'll roll 1d3 +STR +6d6(SA) +18(Sap Adept (Combat)(12) + Knockout Artist(6) ), since i rolled 6 SA damage dices. Am i correct?

Your character has 3d6 sneak attack dice.

Knockout Artist adds +1 damage/sneak attack die rolled.

Sap Adept adds +2 damage/sneak attack die rolled.

Sap Master lets you roll your sneak attack dice twice.

In the case you mention above, you have a character with 3d6 sneak attack. Which means that when he attacks with these feats and the circumstances are just right, he deals:

6d6+18 nonlethal sneak attack damage, added to whatever your base damage with the sap is.

Problem solved
