This post is a compilation of formulas that other people have posted in regards to finding out how each stat works.

All skills are of the same formula.

effect = skill piece * (stat piece + ability piece)

With a simple look at this structure assume all 3 get a value of 1 so

effect = 1* ( 1+ 1) = 2

If we increase skill by 1 we get a 4

but if we increase stat by 1 we get a 3

The nature of the formula automatically gives the skill level the most impact.

Auto Damage = (0.158 *(STR)^0.5 + 0.061 * (Ability )^0.5+0.95) * PhysicalDamage + ElementalDamage

-Energy cost does NOT change with an increase to NATURE MAGIC (Elvra)

- Energy cost does NOT change with an increase to FOCUS (Elvra)

- Energy cost DOES change with an increase to SKILL Level (Elvra)

- Health formula found by (HomoLudens):

- H[max] = 6.25 * ( VIT[stat] + VIT[effects] ) + ( H[item] + H[effects] )

- Energy formula found by (HomoLudens):

- E[max] = ( 6.25 - 0.02 5* WGT ) * ( FOC[stat] + FOC[effects] ) + ( E[item] + E[effects] )

- Weight formula found by (HomoLudens) where Energy becomes 0 at Weight max:

- WGT[max]=250

- Defense formula found by (HomoLudens):

- DEF = 2 * DEX + ( DEF[item] + DEF[effects] )

- Attack formula found by (HomoLudens):

- ATK = 1 * DEX + ( ATK[item] + ATK[effects] )

- Nature Touch to Energy quadratic polynom found by (HomoLudens):

- y = 0.1323x^2 + 1.0425x + 0.4703 with R^2 = 0.9998

- Death Penalty numbers found by (Elvra)

Death Number [effects] = T[effects] where T[effects] is equaled to the time effect is active, % Energy/Health Decrease

0 [None] = None

1 [Resurrected] = 1 minute 0 seconds, 0%

2 [Curse of the Fallen] = 1 minute 0 seconds, 10%

3 [Curse of the Fallen] = 1 minute 15 seconds, 20%

4 [Curse of the Fallen] = 1 minute 30 seconds, 30%

5 [Curse of the Fallen] = 1 minute 45 seconds, 40%

6 [Curse of the Fallen] = 2 minutes 0 seconds, 50%

7 [Curse of the Fallen] = 2 minutes 0 seconds, 50%

8 [Curse of the Fallen] = 2 minutes 0 seconds, 50%

9 [Curse of the Fallen] = 2 minutes 0 seconds, 50%

__How armor affects PVP damage__

[quote="Papi"]Each time you hit the game uses a random number generator to pick a value between your max and half your max. So your average damage will be 75% of your listed max and your Minimum damage will be half your Max damage. Of course this is only against a mob with zero armor.

Max is the auto damage that is listed on your stats page

Average damage = 75% of maxMin damage = 50% of max

Your Max damage and the opponents Armor determine what percentage of your damage makes it through the armor using this formula:

% damage taken = Max/(Max+Armor/2)
You take your max damage as listed in your stats page say it is 400,

And say the armor of your opponent is 200,The % damage you opponent will take is 400/(400+100) or 80% of the random damage you do.

Since you will average 75% or 300 per swing, the average damage your opponent will take is 240.

This was done in the arena with a level 91 druid who did 125 damage. And a level 91 warrior who took off pieces of armor to get different armor values.

850 data points were taken to calculate 8 values for the average, max and min damage.This formula fits very nicely over the data points taken.

Not included is how your damage is effected by the level of the mob. That is next.

Edited to state this is pvp only. Pve is still a mystery.[/quote]

Firebolt formula from update 3. It is obviously outdated, but we can use this as a basis for creating a formula for update 4

= 5.5 + (6 * (Skill) + 11) * (.1054 * (Sqrt(Focus) - Sqrt(10)) + .02793 * Sqrt(Ability) + 1)
