I made this calculator out of frustration of not fully understand FFXI damage mechanics and always seeing references to online calculators but not being able to find one.

Big shout out to Sakiro for the many hours of discussing game mechanics and what is in/out of era to make this possible.

My hope is to have the community try it out and let me know if they think there is anything blatantly wrong or that can be improved to make it more accurate.

I have seen some strange things on Nasomi that don't seem to fit with retail or the equations for damage online.

If you have any questions feel free to message Odiin/Bolmster in game. I'm on after 9PM EST a few nights a week.

https://www.dropbox.com/scl/fi/uqqwouxg ... ct1yb4me4b Blue fields like this are for data entry. Do not enter data in other fields.

These are your results, there are also some other yellow and green fields to help you understand your results.

1. Calculates melee damage and physical weapon skills only

2. Won't work for dual weild or H2H. That may come in the future. Also, if your a THF sorry, i didnt work in the extra SA and TA DEX/AGI damage modifiers specific to you homies.

3. Monster stats are taken from the best data I could find online and some testing. Need confirmation on them.

4. You choose the pDIF(normal and crit) caps you think are appropriate. Nasomi may be different from retail. Who knows.

4.a. Normal retail cap is reported between 2-2.4 and for crit 3, however, there is also a 1.05 multiplier I do not include in the calculations

4.b. If you want to include the 1.05 multiplier just include it in the cap you set. Ex: If you think cap is 2.4, then 2.4*1.05 = 2.52 (enter this)

5. Multihit WS use the calculated fTP on first hit, subsequent hits have an fTP of 1 unless the WS has fTP replication.

6. Although hit rate for WS hits after the first is calculated. You choose how many hits miss in the data entry section.

6.a. WS hit rate is for information purposes only. Ex: If you see that it is 50% and your WS is 4 hit, you may want to be realistic and put 2 misses.

6.b. This goes the same for multihit procs, they will all connect, but if you want to triple attack and you see your hit rate is 50% you may want to choose doubleattack instead to be realistic.

6.c. The reason i give the option for you to decide is because i want you to be able to see the full potential of the WS (which is the fun part) without having to guess your stats or put unrealistic ones in.

7. Multihits like double attacks that proc on WS will not get a crit or 2-3x relic damage proc. They also have ftp set to 1 and do not benefit from fTP replication, but do benefit from WSC modifiers.

8. If you want your WS to crit once then you choose 1 hit crit, this will modify the pDIF by +1. This is the same modfication as sneak attack (essentially a force crit).

8.a. It is my understanding that if you force crit through sneak attack, you cannot crit ontop of that for a total pDIF modification of +2.

8.b. So when you choose to crit once or on all hits, choosing the sneak attack buff will not change your damage output.

8.c. Critting on all hits should only be possible with weaponskills that say "Chance of critical hits vary with TP, however, i think on Nasomi that may be up in the air.

9. Melee DPS is calculated using the delay, % DA, TA, crit, hit rate and relic procs. The reason we do not ask for this info in the WS portion is because you choose to force a crit, miss, or multihit proc.

10. *After finding the tp generated from melee we add in the tp generated from the first WS in order to get the total steady state TP which calculates how many WS per minute you put out. This of course can change if you choose your ws to proc multihits

11. Most equations taken from ffxicyclopedia or bgwiki between 2007-2010 web page updates. I believe equations for basic damage specific to 1hand/2hand/weapon type are out of era for nasomi.

12. I tried to apply floor (round down) correctly in most places. I believe I got them correct but most of the basic equations are broken down at the bottom of the sheet.

12.a. You can check them there if you are interested in specifics like how fSTR is calculated if you want.

13. Some things I think are also possible on Nasomi and not retail are DA on every hit of a WS instead of 2 max, and critting on WS that don't say "Chance of critical hit varies with TP".

14. Also i think Kirin's Def may be slightly higher than what i have listed due to people reporting higher avg gekko's than other ws even while being at around 1k Attack.

Lets Take Catastrophe as an example

-At my current stats on Lesser Colibri i manage to actually hit values between 800-1250 quite regularly, but i will occasionally spike to 1450 without double attack procs.

-My calculator says my melee swings no food should be between 172 and 264 which seems accurate.

-However, WS says 742-1146 but i hit 1250 very often, the only way i can replicate this is by changing the cata mods to 50%STR/50%INT which would be after 2007 era. So maybe those are the real modifiers?

-However, how can i explain the 1450 damage? well since my tp suggests one hit, and the equations don't bring me anywhere near that nor my average damage. I think you can crit on any WS on Nasomi.

-It could be that the PDIF values I have are off, but it seems unlikely given all the retail data suggesting between 2.25-2.4 before the 1.05% multiplier.

-Probably there is something strange going on with Nasomi's code. I have also spoken to many players that have strange experience with damge. Like being able to do much more damage with SA on higher level mobs than lower lvl ones.

-Also, I notice sometimes my damage drops way lower than the equations, but only on very strong targets. Another thing maybe Nasomi worked in somehow.

-I also notice i melee slightly harder than expectedbut only by about 10 damage.

-I would appreciate anyone to review the equations and let me know if i made a mistake somewhere. Please show me with example calculations and real numbers. It helps a lot!
