Hello; have you ever wondered how a new equipment will change your Wizard? Is it for better or for worse, and by how much?
This is something I came up with last night for my guildmate (who asked whether equip A or equip B is better).
This formula is used to calculate a wizard’s "power"; the higher, the better. I apologize in advance if this formula had been posted before.
[(Crit. Rate^-1 - 1)Magic + (Magic * Crit. Damage)] * (Crit. Rate * Magic Amp.)
– or -
[(1/C - 1)A + AD)BC
A - Magic (From Character window)
B - Magic Amp. (1.00 base, 1% is 0.01)
C - Crit. Rate (0.05 base, 1% is 0.01)
D - Crit. Damage (1.20 base, 1% is 0.01)
- also -
[(Crit. Rate * Crit. Damage + 1)] * (Magic * Magic Amp.)
– or -
(CD + 1)AB
A – Magic (From Character window)
B – Magic Amp. (1.00 base, 1% is 0.01)
C – Crit. Rate (0.05 base, 1% is 0.01)
D – Crit. Damage (0.20 base, 1% is 0.01)
How to use it?
Magic: Your Magic Attack number in Character window [C]
Magic Amp.: The total of your Magic Amplification. The base is 1.00.
For example, if you have two equipments that add 7% Magic Amplification each, your "Magic Amp." would be 1.14.
Crit. Rate: Your total Critical Rate, including a 0.05 base.
For example, if you have one Ring of Luck +1 (which adds 10% Critical Rate), your "Crit. Rate" would be 0.15.
Crit. Damage: Your total Critical Damage, including a 1.20 base for the first formula, or including a 0.20 base for the second formula.
For example, if you have two orbs that add 10% Critical Damage each and a helmet that adds 20% Critical Damage, your "Crit. Damage" would be 1.60.
If there are any errors whatsoever, please let me know. :%7d
Also, feel free to calculate yours and post it up here. Maybe we can keep a rankings going or something to boost e-peen size.
Mine is 1283.0175.
Edit: I tested a second formula in Excel, and I think this one may be more accurate than the first. wink
Edit: Corrected base Crit. Damage.
Edit: IMPORTANT: REVISED FORMULA; DID SOME TRIALS~
Many thanks to Deltoid for his help.
Edit: Added alternate formula.
