User:The Gates Assassin/Critical Hits

This guide tells you everything there is to know about Critical Hits.

How Critical Hits Work
A lot of people think that if you have multiple skills and attributes that boost critical hits, they add together to equal you critical hit percentage. This is false. Instead of adding them together, they stack multiplicatively:

If you have Critical eye at 13 critical strikes and 14 dagger mastery, Critical eye will give you a +13% chance, Critical Strikes will give you a 13% chance, and dagger mastery will give you a 21.4% chance. So the complement of each number is if you put it over 100 and instead put the %chance to not get a critical hit in. So Critical strikes would start as 13/100 and the complement would be 87/100. Now take the % chance that you won't get a critical hit from that, which is 87%. That as a decimal is .87. Do that with all the numbers and that is .87 x .87 x .786 = .59 (Rounded). So with that you have a 59% chance to not get a critical hit. This means that you have a 41% chance to get a critical hit.

Also keep this in mind: if you hit a moving target, you automatically do a critical hit. Targets that don't kite die, which is good for you, but when facing someone who has half a brain to run, you are wasting skill slots by taking that many.

Now let's try it with this example build down below.

[build prof=Assassin/Dervish CriticalStrikes=12+1+3 EarthPrayers=3 ScytheMastery=12][Way Of The Assassin][Way Of The Master][Critical Eye][Optional][Optional][Optional][Optional][Optional][/build]

So we have:


 * 16% chance via Critical Strikes
 * 19.2% chance via Scythe Mastery
 * 37% chance via Way of the Assassin
 * 35% chance via Way of the Master
 * 16% chance via Critical Eye


 * 84/100
 * 80.8/100
 * 63/100
 * 65/100
 * 84/100

Those are the complements of all the numbers. Now we multiply them together to get: 23.3% chance to not get a critical hit or 76.6% chance. So you are getting a critical hit 3/4 of the time.

Damage
A critical hit is ~141% of your maximum damage. So if your maximum damage is 50, you would multiply that by 1.41 to get what you would deal in a critical hit. This will ignore all bonus damage and any separate damage such as barbs.

Auto-Critical Hits
If you are attacking someone who is running away from you, and you hit them in the back, you will always get a critical hit. So let's imagine this: You are a monk being chased by a warrior. If you move in a straight line forever, you will never be hit, because you are moving at equal speeds. If the warrior is moving faster than you, you take critical hits EVERY TIME THEY HIT YOU. Simple way to stop this is to run in circles and strafe as opposed to simply running away.
