# 3.0 Critical Hit Chance & Damage Formulae

Critical Hit Chance

I saw this amazing open source google.doc on the blue garter forums which had A LOT of Critical Hit Data, so I gathered up my own Data-Points, then asked Viridiana, who I know has been gathering hundreds of Data Points, to add his to this google.doc… 354-760 Critical Hit Rating almost. Fantastic.

# 3.0 Skillspeeds effect on GCD and DoTs

Mikal Mirkas has done an absolutely beautiful analysis on Skillspeed and came to the conclusion that there’s a 26-27 flip-flop each new “Skillspeed Threshold”, averaging out the Skillspeed shift to 26.5.

However, the first few points of skillspeed always seem to scale Skillspeed differently. As a precaution, I’m going to use the Japanese base GCD of 2.50256, giving us a new Skillspeed formula of:

2.50256-(0.01*(Skillspeed-354)/26.5)

Next, we know that Skillspeed Affects DoT damage. I don’t have many Data-Points for this unfortunately, but they’re roughly accurate and are tied to my Damage Calculation Formulae.

It’s pretty tight, but it looks like the Skillspeed Mod is approximately:

(1+(skillspeed-354)*0.000138)

If you’ve read my previous post about the Damage Formulae, this Skillspeed Mod will fit under the buffs section when calculating damage. Alternatively, you can multiply it by the DoT potency. It’s the same effect.

# 3.0 Damage Calculations for the Dragoon

Okay, here it goes. SquareEnix looks like they may of changed more than just the stats themselves. It appears there’s no longer a base damage value which my old model used to plus on top of the Strength modifier, after it’s been multiplied by 0.075.

This change to damage changes a lot of things. For example, the Strength Coefficient is now 0.011, and the Determination Coefficient is 0.0001368, which makes Determination scale almost 4.5 times less than 2.5X for Weapon Skills.

So, here’s the Updated Models, which, are a WIP:

Weapon Skills:
((Potency*0.01005)*(WD*0.0400573+1)*(STR*0.1104171)*(DET*0.0001368+1)*BUFFS)-1

Auto-Attacks:
((WD*0.0319937+1)*(STR*0.1387779)*(*DET*0.0001513+1)*BUFFS)-1

Skillspeed Mod for DoTs:
(1+(skillspeed-354)*0.0001285) – Note, this fits into the Buffs section.

GCD Calculation:
I read through a few sources about GCD on Bluegatr, Reddit and the JP one and now for GCDs I’m using:
2.50256-(0.01*(SS-354)/26.5)

The reason for 2.50256 is because the first 6 values of Skillspeed are valued differently. The Japanese use the 2.50256 number to by-pass the modifier for the first 6 values.

Of course, my Damage Models only work for the Dragoon and are still a WIP, so a few numbers will change.

Also, I spoke to Clorifex (Garlandtools guys) and he mentioned that the game uses whole numbers in every formula he’s encountered so far. Oddly:
1 / 0.0400573 = 24.96426889
1 / 0.1104181 = 9.056486629
1 / 0.0001368 = 7308.289367

There’s a good probability that the game actually Divides WD/STR by whole numbers, rather than multiplying by long decimals.

So, when I rounded these values, I got this:

((POTENCY*0.01005)*(WD/25+1)*(STR/9.05)*(DET/7308+1)*buffs)-1

This only gives me a 0.2 variation error over my model which multiplies values by decimals.

Total cumulative variation error is 3.8871, which is good, considering I still haven’t a clue how the Game rounds up numbers.
