Effect of attack rating on DPS

[Weltmacht]

It would seem as if OP is doing an extraordinary job of *not* confusing them. Would you happen to know the answer to his question?

Wouldn't it be possible to just look at the eqemu source to see how the calculation is done?

Where would I find this? I'm guessing it's a text document in my program files? I'm familiar with basic coding language and stuff but not much of a computer whiz.

They'll tell you!

i am an engineer, and this is true.

Interesting code snippet. However, that doesn't tell us how ATK functions(in the eq sense uses it). The code you posted looks to be for hit rate %, which ATK doesn't affect.

[Skydash]

Ok, so if I read this code right, then your percentage of landing blows is between 65% to 75% if you are >= target level.
And between 50% to 75% if your < target level.

So the most you will ever hit a mob is 75% no matter what you do, and this is only based on level (and skill level which is based on level).

[imajester]

Don't want to post all the code, but if you want to look...

You are thinking of ATK as just one thing. There are two components to ATK (chance to hit and how hard I hit), just as there are two components to AC. The two values combined is your displayed ATK, just as the two combined AC components equal your displayed AC value.
