Example[]
Lets assume we're using the following equipment at level 150:
| Weapon: Arcane Cutlass of Combustion
Armor: Pyromancer's Robe Shield: Celtic Wheel Misc: Warlic's Oblivion Sphere Pet: Poelala Guest: Poelala Spell: Destruction Burst |
With the following stats:
| INT: 250
DEX: 250 LUK: 250 |
Arcane Cutlass of Combustion gives us an additive boost of +28.125% spell damage on Fire spells
Pyromancer's Robes gives us a multiplier of *1.72 for Fire spell damage or *2.22 multiplier when using Imbue Lore
Celtic Wheel gives us 50 INT as stat damage for spells
Warlic's Oblivion Sphere gives us 50 INT and 50 LUK as stat damage for spells
Poelala Pet gives us an additive boost of +10.498% spell damage with 350 INT
Poelala Guest gives us an additive boost of +15.748% spell damage with 350 INT
Destruction Burst spell has a base of 179 and a random of 358 as well as an HP cost for an additive boost of +50% spell damage
Spell Raw Power[]
First, lets calculate Normal Spell Power:
Average Normal Spell Base = (Spell Base) + (Spell Random) / 2 + (Spell Stat Damage) * (Spell Stat%) / 2
Therefore:
Average Normal Spell Base = 179 + 358 / 2 + (350 / 4 [INT] + 300 *3/80 [LUK]) * 11.1 / 2 = 906.0625
Accuracy[]
Now, lets calculate the spell's average hit rate.
For this, we'll assume an enemy with:
| Magic: 54
DEX: 250 LUK: 225 Fire Resistance: 120% |
Your accuracy is:
Attacker Value (spell) = Spell BTH + Stat BTH + Additive BTH Modifiers (if any)
Therefore:
Attacker Value (spell) = 38 + 350*3/40 [INT] + 250*3/40 [DEX] + 300/40 [LUK] = 90.5
And for the monster:
Defender Value = Blocking Defense + DEX/8 + LUK/40
Therefore:
Defender Value = 54 + 250/8 + 225/40 = 90.875
Finally, your accuracy is:
Chance to Hit = (100 + Attacker Value - Defender Value) / 100
Therefore:
Chance to Hit = (100 + 90.5 - 90.875) / 100 = 0.99625
Additive and Multipliers[]
Now, we have to add our damage modifiers:
For the additive multiplier, the formula is as follows:
Additive Multiplier = 1 + Total Additive Damage
In this case, when adding all additive sources:
Additive Multiplier = 1 + 0.5 [Spell HP Cost] + 0.28125 [Fire Cutlass] + 0.10498 [Poelala Pet] + 0.15748 [Poelala Guest] = 2.04371
And for the multiplicative multiplier, the formula is:
Multiplicative Multiplier = Product of All Multiplicative Damage
And therefore, we get:
Multiplicative Multiplier = 1.72 [Pyromancer's Robe] or 2.22 [Pyromancer's Robe Imbue Lored]
So to calculate our damage, well use:
Spell Average Damage = (Average Spell Base) * (Hit Rate) * (Additive Multiplier) * (Multiplicative Multiplier) * (Resistance)
And gives us:
Spell Average Damage = 906.0625 * 0.99625 * 2.04371 * 1.72 * 1.2 = 3807.636257
OR:
Spell Average Damage = 906.0625 * 0.99625 * 2.04371 * 2.22 * 1.2 = 4914.507262 [Imbue Lored]
