Enter your stat and ability values, and the calculator returns the results.Auto Attack FormulaFirst 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 DamageLevel 50 Skill FormulasThese 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.Druid485Level 50 Abundance Health Boost = 19.592*sqrt(Focus) + 6.1866*sqrt(Nature Magic) + 411.94264Level 50 Energy Harvest Energy Stolen = 16.908*sqrt(Focus) + 4.7469*sqrt(Nature Magic) + 132.4387Level 50 Howling Wind Attack Reduction = 38.207*sqrt(Focus) + 10.886*sqrt(Nature Magic) + 693.63328Level 50 Lightning Strike Damage = 73.547*sqrt(Focus) + 20.743*sqrt(Nature Magic) + 327.29967Level 50 Nature's Breath Heal = 14.491*sqrt(Focus) + 4.5689*sqrt(Nature Magic) + 244437Level 50 Nature's Touch Heal = 28.89*sqrt(Focus) + 8.9361*sqrt(Nature Magic) + 452.42485Level 50 Sanctuary Damage Absorbed = 5.5015*sqrt(Focus) + 2.6713*sqrt(Nature Magic) + 520.82695Level 50 Shield of Bark Armor Boost = 12.287*sqrt(Focus) + 3.7807*sqrt(Nature Magic) + 195.08544Level 50 Strangling Vines Tick Damage = 49.811*sqrt(Focus) + 15.81*sqrt(Nature Magic) + 265.82485Level 50 Ward Resistance Boost = 12.214*sqrt(Focus) + 3.8608*sqrt(Nature Magic) + 193.29All druid wards follow the same formula.
