!!!! WARNING !!!! LONG POST !!!!

The information regarding Attack Power provided on the Rogue FAQ is good, but a little convoluted in its explanation. Seped and Aylith has provided numerous explanations regarding the factor of weapon speed in the damage output equation, but I thought I'd give it a long shot and try to take into account as many variables as possible.

Rogue FAQ中提供的Attack Power相关信息很不错，但是解释方式令人模糊。Seped 和 Aylith 已经提供了无数有关武器速度在伤害输出中所起的作用，但我还是决定仔细考虑一遍并代入尽可能多的变量。

The major thing to remember is that Attack Power adds to your DPS. It's not a flat damage bonus. This is to balance things so that Attack Power does not drasticly favor faster weapons -- you get a DPS increase which means it's independent of speed.

很重要的一点就是Attack Power所增加的是DPS。这并不是简单的伤害增加。它是出于平衡性的目的，使Attack Power不会过分偏袒快速武器--你得到的是DPS增加，意味着它不依赖于武器速度。

However, such bonus has an interesting side effect to instant attacks. In an instant attack, the speed of the weapon plays no role. This means that two weapons with the same DPS, the slower weapon will produce harder hitting specials (check out the comparison between Julie’s Dagger and Thrash Blade below) and, a slower weapon with a lower DPS has a fairly high chance of being able to out-damage a faster weapon with higher DPS in the main hand of a rogue. This will also enlighten many on the idea of combat rogue – why rogues would choose to use big, heavy hitting main hand weapons instead of small nimble daggers and why for PvE purposes where Sinister Strike is THE attack of choice, a slow sword will outshine a fast dagger.

然而，这种攻击奖励对即时攻击产生了副作用。在即时攻击中，武器速度无关紧要。如果说有两把相同DPS的武器，慢的一把会造成更高的特殊攻击伤害，于是盗贼主手持有一把低DPS慢速武器有相当几率比另一把高DPS快速武器输出更多伤害。这就产生了所谓 战斗盗贼 的概念 -- 这也就解释了一些盗贼会选择厚重的主手武器而并非小巧灵活的匕首，并且在险恶攻击占主导PVE之中为什么慢速剑让快速匕首相形见绌。

For the following comparison, assume you have enough +Attack Power to give you a 30dps bonus. Also VERY IMPORTANT to point out is that these calculations are AVERAGE damages. The damage variance on the weapons is +/- 30% of its average damage per hit (weapon speed x dps). You can work it out. On a weapon like Widowmaker that is 31.6dps 1.9 spd, the average damage is 60, +/- 30% will give you damage range of 43 to 78 damage, which is exactly what the weapon description says.

在接下来的比较中，假设你有足够的 +Attack Power 为你提供30 DPS增加。还要指出重要的一点就是以下计算均为平均伤害。武器伤害的浮动范围是其平均每击伤害（武器速度*DPS）的+/-30%。对于31.6DPS 1.9SPD的Widowmaker来说，其平均伤害为60，+/-30%就是43-78，这恰好是武器说明上所描述的。

Weapon 1:

- [ Julie's Dagger] - 36.5dps, 1.30 speed.

In an instant attack, you would do (36.5 dps + 30 dps) x 1.3 speed = 86.45 damage

If the attack is Rank 8 (final) Sinister Strike, you get 68 damage bonus, making your damage = 154.45 damage (I got this information off Thottbot, I hope it's correct)

在一次即时攻击中，你能造成(36.5 dps + 30 dps) x 1.3 速度 = 86.45 伤害
如果这是一次等级8（最高级）的险恶攻击，你能得到68的攻击奖励，使你的总伤害为 = 154.45 伤害

Weapon 2:

- [ Widowmake] - 31.6dps, 1.90 speed

In an instant attack, you would do (31.6 dps + 30 dps) x 1.9 speed = 117.04 damage

With a Rank 8 Sinister Strike, you would do 185.04 damage

在一次即时攻击中，你造成(31.6 dps + 30 dps) x 1.9 速度 = 117.04 伤害
如果是一次等级8的险恶攻击，你造成185.04 伤害

Weapon 3 (for reference):

- [Thrash Blade] - 35.2dps, 2.70 speed

(35.2dps + 30dps) x 2.7 speed = 176.04 damage

With Rank 8 SS: 176.04 + 68 = 244.04 damage

(35.2dps + 30dps) x 2.7 速度 = 176.04 伤害
等级8的险恶攻击：176.04 + 68 = 244.04 伤害

Now if you consider the fact that the rate at which a Rogue conducts sinister strike is directly determined by the rate at which a Rogue regenerates energy (which is approximately 2 seconds per tick, 20 energy every two seconds), and the fact that it costs 40 energy to conduct Sinister Strike (with improved SS rank 2 talent). This means you can use Sinister Strike with Julie's Dagger as many times as you can use it with Widowmaker. Noting the 185 damage vs. the 154 damage (barring crits), the Widowmaker clearly becomes a better choice in terms of pure Sinister Strike damage even though it has a lower DPS. The Thrash Blade, at this point, burns the competition.

首先你得弄明白的是盗贼使用险恶攻击的频率直接取决于其能量回复（2秒1拍，也就是2秒回复20能量）并且一次险恶攻击消耗40能量（天赋：强化险恶攻击2级）。这就意味着不论你用Widowmaker还是Julie's Dagger你都能使出同样次数的险恶攻击。注意185 damage vs. the 154 damage（不包括重击），对于纯粹的险恶攻击来说Widowmaker明显是一个更好的选择，尽管它的DPS低。而此时，Thrash Blade远远胜出。

To extend the analysis, let's say your typical Rogue fight vs. a mob lasts about 20 seconds (give or take) and the only skill you used was Sinister Strike (no Evsicerate). You would be able to do:

20 seconds x (1 tick / 2 seconds) x (20 energy / tick) = 200 energy worth

200 energy + initial 100 energy with which you started the fight = 300 energy

floor(300 energy x 1 Sinister Strike / 40 energy) = 7 Sinister Strikes

我们来进行更深入的分析，假设一场典型的盗贼杀怪战斗持续20秒并且你只使用险恶攻击（不算剔骨）你能造成：

20 秒 x (1 拍 / 2 秒) x (20 能量 / 拍) = 200 能量
200 能量 + 战斗开始前的 100 能量 = 300 能量
取整(300 能量 x 1 险恶攻击 / 40 能量) = 7 险恶攻击

Now, assume all the hits landed with no criticals...

现在假设没有重击存在：

Julie's Dagger:

(30 + 36.5 dps) x 20 seconds + 7 Sinister Strikes x 154 damage = 2408 damage

(30 + 36.5 dps) x 20 秒 + 7 险恶攻击 x 154 伤害 = 2408 伤害

Widowmaker:

(30 + 31.6 dps) x 20 seconds + 7 SS x 185 damage = 2527 damage

(30 + 31.6 dps) x 20 秒 + 7 险恶攻击 x 185 伤害 = 2527 伤害

Thrash Blade:

(30 + 32.5 dps) x 20 seconds + 7 SS x 244 damage = 3012 damage

(30 + 32.5 dps) x 20 秒 + 7 险恶攻击 x 244 伤害 = 3012 伤害

We see Widowmaker still winning vs. Julie's... Thrash Blade clearly still a better choice...

看，Widowmaker还是比Julie's要好...Thrash Blade依旧胜出...

Let's put in Crits:

Assume a typical rogue with average equipment has 15% base crit chance (actual is slightly higher). A smart rogue would have 5 points in Lethality Talent, which means 30% damage bonus when you crit with SS, Ambush, Backstab, and Hemorrhage.

Assume also that on a regular crit, the damage dealt is doubled. i.e. 200% of original damage (100% more). Similarly, a Sinister Strike crit would deal 230% of original damage from talents (130% more). With me so far? Good, things are about to get unpretty:

现在我们把重击也算进去：

假设一个持有普通装备的盗贼拥有15%的重击率（实际上会更高些）。聪明的盗贼会在天赋：致命伤上投入5点，从而使险恶攻击，伏击，背刺和放血的重击伤害都提升30%。

再假设在普通的重击中造成的伤害是加倍的，就是原始伤害的200%（也就是说多造成了100%或更多的伤害）。于是，一次重击的险恶攻击造成了230%原始伤害（意味着多造成了130%原始伤害）：

To calculate average non-special attack damage obtained from 15% crit chance in 20 seconds, we have

20 seconds / weapon speed * 15% crit chance * dps * weapon speed = crit damage added

(swings taken, multiply by crit% to get # of swings that crits, then multiply by the weapon damage per hit for those hits)

The above simplifies to:

20 seconds x 15% crit chance x Weapon DPS = crit damage added for non-specials

and similarly we get:

7 x 15% crit x SS Damage x 130% damage bonus = crit damage added for sinister strikes

为了计算20秒内普通攻击在重击时（15%几率）所增加的伤害，我们有

20 秒 / 武器速度 * 15% 重击率 * dps * 武器速度 = 重击伤害增加
（即攻击次数乘以重击率得到重击次数，再乘以武器的每击伤害）

以上简化为：

20 秒 x 15% 重击率 x 武器 DPS = 普通攻击重击伤害增加

类似的我们得到了：

7 x 15% 重击 x 险恶攻击伤害 x 130% 重击伤害增加 = 险恶攻击的重击伤害增加

Now the fun begins:

Julie’s Dagger

20 x 0.15 x 66.5 dps = 199.5 crit damage added

199.5 + 20 x 66.5 dps = 1529.5 damage from regular attacks with crits accounted

7 x 15% x 154 x 130% = 210 crit damage added from SS

7 x 154 + 210 = 1288 damage from SS with crits accounted

Julie’s Dagger total: 2817 damage

20 x 0.15 x 66.5 dps = 199.5 重击伤害增加
199.5 + 20 x 66.5 dps = 1529.5 包含重击的普通攻击伤害
7 x 15% x 154 x 130% = 210 险恶攻击重击伤害增加
7 x 154 + 210 = 1288 包含重击的险恶攻击伤害



Julie’s Dagger 合计: 2817 伤害

Widowmaker

20 x 0.15 x 61.6 dps = 184.8 crit damage added

61.6 x 20 + 184.8 = 1416.8 damage from regular attacks with crits

7 x 15% x 185 x 130% = 252 crit damage added from SS

7 x 185 + 252 = 1547 damage from SS with crits accounted

Widowmaker Total: 2964.3 damage

20 x 0.15 x 61.6 dps = 184.8 重击伤害增加
61.6 x 20 + 184.8 = 1416.8 包含重击的普通攻击伤害
7 x 15% x 185 x 130% = 252 险恶攻击重击伤害增加
7 x 185 + 252 = 1547 包含重击的险恶攻击伤害

Widowmaker 合计: 2964.3 伤害

Thrash Blade

(I’m gonna simplify things here)

20 x 65.2 dps x 115% = 1499.6 damage from regular attacks with crits (you notice it’s less than that of Julie’s Dagger, b/c Julie’s Dagger has higher DPS)

7 x 15% x 244 x 130% = 333.06 crit damage added from SS

7 x 244 + 333.06 = 2041 damage from SS with crits accounted

Thrash Blade Total: 3540 damage

20 x 65.2 dps x 115% = 1499.6 包含重击的普通攻击伤害(你会注意到这比Julie’s Dagger低，当然是因为Julie’s Dagger有更高的DPS)
7 x 15% x 244 x 130% = 333.06 险恶攻击重击伤害增加
7 x 244 + 333.06 = 2041 包含重击的险恶攻击伤害

Thrash Blade 合计: 3540 伤害

Still with me? Good, because I almost lost myself.

Let’s Account in Poison damage to even the battlefield: (And remember, Poison application is % chance, so faster your weapon, more likely you’ll get a poison proc in a fixed period)

20% application chance, 130 nature damage on average. A rogue would probably have 5 points in Improved Instant Poison, which means 10% more chance of applying Instant Poison, making it 30%

好了现在我们把毒也加进去（要记住，毒以%几率触发，所以快速武器为你带来更多的毒触发次数）

20%几率触发，平均130自然伤害。有不少盗贼会在天赋：强化急性毒上投入5点，从而使其触发几率上升10%达到30%

Now

7 SS x 30% chance x 130 damage = 273 damage from IP while SSing

7 险恶攻击 x 30% 几率 x 130 伤害 = 273 险恶攻击造成的急性毒伤害

Julie’s Dagger

20 seconds / 1.3 spd x 30% chance x 130 damage = 600 damage from IP

2817 + 600 + 273 = total

Total: 3690 dmg

20 秒 / 1.3 速度 x 30% 几率 x 130 伤害 = 600 普通攻击急性毒伤害
2817 + 600 + 273 = 总共伤害
合计: 3690 伤害

Widowmaker

20 seconds / 1.9 spd x 30% chance x 130 dmg = 410 damage from IP

Total: 3647 dmg

20 秒 / 1.9 速度 x 30% 几率 x 130 伤害 = 410 普通攻击急性毒伤害
合计: 3647 伤害

Thrash Blade

20 seconds / 2.7 spd x 30% chance x 130 dmg = 288.8 dmg from IP

Total: 3829 dmg

20 秒 / 2.7 速度 x 30% 几率 x 130 伤害 = 288.8 普通攻击急性毒伤害
合计: 3829 伤害

Hmm… Julie’s Dagger is looking up from here, but it’s still no contest when taken up against the Thrash Blade. From a PVP standpoint, you would rarely consider adding instant poison on your main blade – crippling gives you huge mobility advantages that you simply cannot ignore, which means if you only used SS in PvP, Widowmaker STILL wins out. If you’re a combat rogue or Sinister Strike is your primary attack (in the case of PvE Soloing), pick something SLOW for your main hand if you can!

怎么样...Julie’s Dagger有不少进步了，但还是比不上Thrash Blade。从PVP的角度来看，你很少会考虑在主手武器上涂急性毒 -- 残废毒给与你无法拒绝的巨大优势，也就是说如果你在PVP中只用险恶攻击，那Widowmaker还是赢家。如果你是一个战斗盗贼或者险恶攻击是你的主要攻击方式（在PVE练级中），那么尽量选一把慢速的主手武器吧！

Now let’s consider PvP or Group situations where you can Backstab a lot. What if we use Backstab instead of SS? This puts Thrash Blade out of the equation. First things we notice is that, by changing from SS to BS, crits play a more important role while the non-special DPS remains the same. So we only have to do calculation Comparisons between SS and BS.

Final Rank Backstab: 150% weapon damage + 175, 60 energy use

With Improved Backstab rank 3, you get 30% bonus to crit while BSing, making your BS crit rate somewhere around 45%.

With Rank 5 Opportunity, you get 20% damage bonus to BS, Garrote and Ambush

So your BS damage will be 180% Weapon Damage + 210 flat (that's what it says on my tooltip).

300 energy for 20 seconds of combat = 5 backstabs.

然后我们考虑PVP或组队时的情况，此时你会经常使用背刺。那么会发生什么呢？这就把Thrash Blade丢在了一边。首先我们注意到从险恶攻击切换到背刺时重击变得更为重要，而普通攻击的DPS并未发生变化。所以我们为险恶攻击和背刺的比较做一个计算。

最高级 背刺: 150% 武器伤害 + 175, 60 能量使用
加上 天赋：强化背刺 等级3，你的背刺重击率提高了30%最终达到45%左右。
加上 天赋：时机 等级5，你在背刺，绞喉和伏击时得到20%的伤害提升。
于是你的背刺伤害会是 180% 武器伤害 + 210 左右（我的工具条上就是这么说的）。

300 能量 对于 20 秒的战斗 = 5 背刺

Julie’s Dagger BS

BS non crit = 66.5 x 1.3 x 1.8 + 210 = 365.61

5 x 365.61 = 1828 damage if no crits

5 x 45% BS crit x 365.61 x 130% damage bonus for crits = 1069.41 damage from crits

Total from BS: 2897.4 dmg

Poison from BS:

5 x 30% x 130 = 195

Total damage from poison and regular attacks: 2897 dmg + 66.5 x 20 x 115% + 600 + 195 poison = 5222 damage

背刺 无重击 = 66.5 x 1.3 x 1.8 + 210 = 365.61
5 x 365.61 = 1828 无重击背刺伤害
5 x 45% BS 重击 x 365.61 x 130% 重击伤害提升 = 1069.41 背刺重击增加伤害
背刺伤害合计: 2897.4 伤害
背刺造成的毒伤害:
5 x 30% x 130 = 195
合计: 2897 dmg + 66.5 x 20 x 115% + 600 + 195 poison = 5222 伤害

Widowmaker BS

61.6 x 1.9 x 1.8 + 210 = 420.67 damage per BS non crit

5 x 420.67 = 2103.36 damage if no crits

5 x 45% x 420.67 damge per bs non crit x 130% damage bonus for crits = 1230.46 damage from crits

Total from BS: 3333.5 dmg

Poison from BS = 195

Total damage from poison and regular attacks: 3333.5 + 61.6 x 20 x 1.15 + 410 + 195 = 5355 damage

61.6 x 1.9 x 1.8 + 210 = 420.67 无重击背刺单次伤害
5 x 420.67 = 2103.36 无重击背刺伤害
5 x 45% x 420.67 x 130% 重击伤害提升 = 1230.46 背刺重击增加伤害
背刺伤害合计: 3333.5 伤害
背刺造成的毒伤害 = 195
合计: 3333.5 + 61.6 x 20 x 1.15 + 410 + 195 = 5355 伤害

Pretty comparable, ain’t it? You’ll notice poison makes up for quite a bit of the room between the two daggers. Without Instant Poison, the Widowmaker, a lvl 42 dagger, will CLEARLY win out vs. Julie’s Dagger, a lvl 50 dagger. You’ll also notice that, carefully employing backstabs, the total damage being put forth by these daggers completely blows Sinister Strike damage away (if you spec correctly, also remember that I "threw away" the damage of half a sinister strike early on in this discussion because i took the floor of the # of SS you can do in 20 seconds). The only downside is position, but the extra chance to crit gives you a much greater ability to take advantage of Seal Fate. In a PvP situation, it’s a matter of how quickly you can disable your enemy before retaliation comes in full force. In cases like these, the initial damage you do in the first 3-4 seconds can make a life / death difference. It doesn’t matter if in 5 minutes your damage will outshine mine if for the first 30 seconds I can blow you away. That’s where heavy-hitting weapons really shine.

一目了然，不是吗？你会注意到毒对两把匕首都造成很大的影响。如果没有强化急性毒，Widowmaker，一把42级匕首轻松胜出Julie’s Dagger，一把50级匕首。你同样能注意到，在熟练使用背刺时，那几把匕首所输出的伤害把险恶攻击的伤害远远抛在了身后（前提是你选择了合适的天赋，不过还要记住我在以上计算中因为取整忽略了半个险恶攻击）。使用匕首的唯一缺点就是位置，但额外的重击几率能在天赋：决定命运上轻而易举的为你带来巨大的优势。在PVP情况下，最重要的就是要尽快地砍翻对手不让其有等待援助并报仇的机会，因此你最初3-4秒造成的伤害决定了你的生死存亡。如果我能在30秒内把你打趴下的话我根本不在乎你能在5分钟内比我造成更多的伤害。那才是那些笨重武器有用武之地之时。

Summary:
In 20 seconds of SS + regular damage, Widowmaker does 5.2% more damage than Julie's. When Poison is put into the equation, Widowmaker does 8% less damage than Julie's. In 20 seconds of BS + regular damage, Widowmaker does 7.3% more damage than Julie's. When poison is considered, Widowmaker does 2.5% more damage than Julie's.

Remember, I didn’t into account is the fact that eviscerate, our best finisher, is completely independent of what weapon you use. And, finally, I discounted the effects of using different openers (Cheap Shot vs. Ambush, slower weapon obviously produced higher Ambush damages, etc.) But, if you’re still following through all of this, you will fully understand that the more attack power you have, the more weight your instant attacks will have on your damage output which means that the more important your weapon speed will come into play.

总结：
对于二十秒的险恶攻击+普通攻击，Widowmaker比Julie's多造成5.2%的伤害。在计算中考虑毒的话，Widowmaker比Julie's少造成8%的伤害。在二十秒的背刺+普通攻击中，Widowmaker比Julie's多造成7.3%的伤害。加入毒后，Widowmaker比Julie's多造成2.5%的伤害。

大家要记住，我还未曾考虑起手技所带来的种种影响（偷袭 vs 伏击，慢速武器显然产生更高的伏击伤害，等等）。尽管如此，只要你们看完了这篇文章，应该能清楚明白随着Attack Power的增加，那些即时攻击在伤害输出中扮演的角色也越来越重要，这也意味着武器速度在后期游戏中的关键性。

I've checked my math a few times through, and I've found minor mistakes here and there each time. I hope it's as free of mistakes as possible, but this is the product of one overworked caffeine-laiden brain. Feel free to tear this apart, provide addendums, or corrections.

In the mean time, I'm seriously considering conjuring up an Excel sheet or something to see things easier.

更新

3.5

I thought the off-hand is pretty obvious, but Here's a quickie on the off hand:

Thrash Blade 35.2 dps, 2.7 speed

Julie's Dagger 36.5 dps, 1.3 speed

Placing all the assumptions we've made earlier regarding DPS, average weapon damage etc.

In 20 seconds,

Thrash Blade does:

(35.2 + 30 dps) x 20 seconds x 1.15 (15% chance to crit) = 1500 damage

Poison from Thrash = 20 seconds / 2.7 spd x 30% application chance x 130 nature damage = 289 damage from poison

Julie's Dagger does:

(36.5 + 30 dps) x 20 seconds x 1.15 = 1529 damage

Poison from Julie's = 20 seconds / 1.3 spd x 30% application chance x 130 nature damage = 600 damage from poison

It's pretty easy to see that under the same DPS, weapon speed plays a major role in how much damage you get from poison since the DPS from normal attacks remain the same.

Notice how I completely ignored the damage and hit-rate penalty from using these weapons in off-hand. While the to-hit penalty will affect both the regular attacks and poison applied (by the same percentage regardless of speed), the damage penalty will only affect the attack damage and not poison. This means that poison damage plays an even bigger role than initially calculated.

On the off hand, a faster weapon > slower weapon with the same DPS if you plan to use any type of poison.

Now whether to use a faster weapon with lower DPS or a slower weapon with higher DPS on the offhand is just a matter of working out these numbers and finding a balance.
