避免被碾壓 (Avoiding crushing blows)

[log56 (=1.74818802700620041635)]

If your Defense skill is fully trained for your level, neither more Defense, 
nor Resilience, nor any other kind of bonus can reduce the nominal chance for 
you to receive a Crushing Blow. The only way to reduce your chance of 
receiving a Crushing Blow is for your combined chance to be missed, to dodge, 
to parry, and to block to be so high that the Crushing Blow chance is pushed 
off the bottom end of your attacker's Attack Table. 

假設你的防禦技能在你目前等級練滿，
就算給你再多防禦、韌性或其他加值也無法減低你被碾壓的機率。
唯一免除碾壓的機會，
就是將你的未擊中 (miss)、閃躲 (dodge) 、招架 (parry) 和格檔 (block) 機率
相加總，其數值夠高，
才有可能將碾壓從攻擊可能發生的列表 (attack table) 中移除。

Since attacks from a level 73 boss are 0.6% less likely to miss or be dodge, 
parried, or blocked by a level 70 character, a tank must have a 
miss/dodge/parry/block rate of 102.4% against a level 70 mob to be immune to 
crushing blows. This amount of avoidance and mitigation pushes crushing blows 
(as well as crits and normal hits) off the Attack Table. 

對 lv70 的玩家來說，
要經由 未擊中/閃躲/招架/格檔 lv73 的王攻擊，
其機率每一種所需要的量大約會提高 0.6%，
所以對坦克來說，要免除碾壓，你的 未擊中/閃躲/招架/格檔 機率總和至少要有

                                102.4%

這個量會將攻擊可能發生的列表中：碾壓、爆擊、一般命中擠出去。

Use the following formula to determine your miss/dodge/parry/block rate: 

%needed= Base 5% miss + bonus miss from defense + dodge % + parry % + block % 

i.e. 5 + 8,44 + 22,27 + 18,78 + 54,35 = 108,84% Remember to cast Holy Shield 
or Shield Block before checking your block chance in game. 

使用下面的公式來決定你的 未擊中/閃/招/格 機率：

需要啪數 = 基本 5% 未擊中 + 防禦提供的未擊中 + 閃躲 + 招架 + 格檔

記得要檢定被碾壓機率前，先施放神聖之盾或者是盾牌格擋。

[edit] Warriors 
The warrior ability Shield Block increases block rate by 75%, removing 
crushing blows from the miss/dodge/parry/block/crit/crushing-blow table that 
occurs when an opponent attacks, and making the warrior more or less "immune" 
to both crushing blows and critical hits in a PvE environment, but only in 
case that he is immune to crushing blows as shown above. This is because an 
attack that is blocked (as with a shield) cannot be a crushing blow or a 
critical hit -- the three are mutually-exclusive attack results. A warrior 
will take crushing blows if they are hit 3 times in 5 seconds, as the Shield 
Block ability has 2 charges. A mob with an attack speed of 2.0 or faster can 
therefore crush a warrior if he fails to dodge/parry/miss 3 attacks in a row. 

戰士：
戰士的能力「盾牌格擋」提高格擋機率 75%，可以從攻擊可能中擠掉碾壓，
也造就了戰士在 PvE 環境中免疫碾壓和爆擊，但是只有在上述情況成立之下才行。
因為攻擊只要被格擋，就不會被碾壓或爆擊 (因為三者是兩兩互斥的) 。
戰士五秒鐘內受到三次以上的攻擊，便有機會吃到碾壓傷害，
因為盾牌格擋技能只提供兩次的機會提高 75% 格擋機率。
所以當怪的攻速高過 2.0 的時候，戰士無法利用盾牌格擋來免除碾壓。

[edit] Paladins 
Redoubt and Holy Shield together increase the block rate by 60% (30% each). 
However, Redoubt procs randomly and cannot be relied upon. A tankadin 
therefore needs to hit 102.4% with only Holy Shield running. 

This is made much easier with the Libram of Repentance, which increases your 
block rate by 5.3% while Holy Shield is active for a total of 35.3%. 

For a paladin with the Libram of Repentance to be immune to crushing blows 
from bosses, the miss/dodge/parry/block rate must be at least 67.1% and Holy 
Shield must be active at all times. 

Paladins may also want to consider the Improved Holy Shield talent. Since 
Holy Shield is effective for 4 attacks in 10 seconds, it is unlikely to 
expire in less than its full duration. If the paladin is AoE tanking or 
tanking a fast swinging mob, this is a different matter. Improved Holy Shield 
can provide 4 more Holy Shield blocks in that time and increase the amount of 
damage from each Holy Shield proc. 

聖騎士：
盾牌壁壘和神聖之盾合計提高格擋機率 60% (每一項提高 30%)。
然而，盾牌壁壘隨機發動，因而無法完全倚賴該能力。
一個坦帕要免除碾壓則只能將神聖之盾提供的 30% 格擋計算進去。

要避免碾壓，悔悟聖契 http://wowbox.tw/item.php?witem=29388
會是個不錯的選擇，他提高了當神聖之盾 5.3% 的格擋機率，
來到 35.3%。

有了悔悟聖契的聖騎士，剩下的 miss/閃/招/格 機率總和至少要 67.1%，
同時神聖之盾常駐，才能免除碾壓。

聖騎士同時也應該考慮天賦強化神聖之盾。
因為神聖之盾 10 秒內可以作用 4 次，
而時間結束前要消耗掉這四次機會不太高。
但是如果聖騎士要群坦或者面對攻速特快的王，
那又另當別論。強化神聖之盾會提供額外四次作用機會，
同時增加神聖之盾發動時的傷害。


[edit] Druids 
Forget it. You will eat crushing blows. This is why bears have their high 
armor. 

德魯依：
甲..呃，我是說，別考慮了，硬吃碾壓吧，這也是為甚麼熊的ac特高的原因。


You can use the following macro to determine if you can be crushed. Make sure 
you use Shield Block or Holy Shield before you press the button. 

我到底會不會被碾壓？
你可以利用下列巨集來測試你會不會被碾壓。
按下去之前別忘記將盾牌格擋或神聖之盾打開。

/script DEFAULT_CHAT_FRAME:AddMessage("Need 102.4 combined avoidance.
Currently at:",0.8,0.8,1)
/script DEFAULT_CHAT_FRAME:AddMessage(GetDodgeChance()+GetBlockChance() +
GetParryChance() +5+(GetCombatRatingBonus(CR_DEFENSE_SKILL) +
20)*0.04,1,0.5,0)

This macro assumes that you have 20 defense skill from talents. If you have 
less, you need to edit the following: 

上述巨集假設你從天賦中獲得額外的 20 點防禦技能。
如果不夠，請照下列巨集重寫：

(GetCombatRatingBonus(CR_DEFENSE_SKILL) + 20)

填入你從天賦中獲得的防禦技能。
