Auto Attack and Skill Calculator
A calculator made by Bitey that uses these formulas below. Enter your stat and ability values, and the calculator returns the results.


Auto Attack Formula
First posted by Papi, this formula outputs your auto attack damage. Note that attack does not directly affect this. I have slightly adjusted Papi's formula for better precision.

Strength — on your stats page. Includes equipment bonuses.
Weapon Ability — one of the following: staff, totem, wand, bow, dagger, sword, axe, blunt, spear, novelty, and hand to hand.
Physical Damage — the sum of slash, pierce, and crush damage granted by your equipment.
Elemental Damage — the sum of heat, cold, magic, poison, and divine damage granted by your equipment.

Auto Attack Damage = [0.15818*sqrt(Strength) + 0.061069*sqrt(Weapon Ability) + 0.96523] * Physical Damage + Elemental Damage


Level 50 Skill Formulas
These formulas predict the displayed maximum power of skills as shown in your skill page. They should be at least 99% accurate. Note that these formulas are for max level skills only (skills with 50 points in them). Even if you don't have maxed out skills, they are still extremely useful for comparing the relative strengths of different skills.

Energy costs of max level skills are listed on the left.

Super big thanks to Bellatrix for providing three data points each for firestorm and fire attunement. The formulas are out already (unless I made a mistake somewhere).

1465 focus, 3000 fire magic = 5214 firestorm damage
635 focus, 3000 fire magic = 4035 firestorm damage
635 focus, 1800 fire magic = 3720 firestorm damage

1465 focus, 3000 fire magic = 1712 fire attunement boost
635 focus, 3000 fire magic = 1420 fire attunement boost
635 focus, 1800 fire magic = 1296 fire attunement boost

Edit: Formulas updated in original post.

Thanks so much Regenleif! The list keeps getting better

Edit: Formulas updated in original post.

For melee skills, weapon damage can be an extra factor, are you able to create a formula for them also? Would you need data from different weapons?

Edit: Yes, I can now create formulas for skills that include weapon damage.

I'm working on focus vs. skill value graohs for all the mage skills, to find for example after how many focus points would it not be worth it to add focus for firebolt or ice shards dmg

Good luck with this! Would be interesting to see the outcome...

Requesting a sticky for this!

Why would they sticky something that saves people plat?
