Where is my error on the magic dmg formula?

[cdgreg]

I was hoping to do some mathematical testing of gear I do not own on blm by first establishing a base on Marids. However, I can not get the magic dmg formula to match my dmg. Here are the statistics:

On my pure dmg nuke (BLM/RDM) using T4 Thunder in Uggy Pendant range I have:
1.) Caster's Int: 120
V = 541
M = 2.0

2.) Multiple Target Damage Reduction: 1.0

3.) Resist: 1.0

4.) Staff Bonus: 1.15

5.) Day of the Week: 1.0

6.) MB Bonus: 1.0

7.) MAB Bonus: 1.85 (+32 from natural MAB IV, +43 from gear +10 from merits= 85 total )

MY ACTUAL DMG
Thunder 4 on a marid: 1383. This was done on more than 1 mob, and the dmg was consistant.

Formula: Assuming Marid int = 65
[(120-65) * 2) + 541] * 1.85 * 1.15
651 * 1.85 * 1.15
Formula DMG 1385

Formula: Assuming Marid int = 66
[(120-66) * 2) + 541] * 1.85 * 1.15
Formula DMG 1381

I've triple and quadruple checked my MAB and Int levels. Do I need to use "For dINT > 0, but after some inflection point: D = V + (const + (dINT-const) * M / 2))?"

If so what is const? I tried making const 120 (my constant int) but it did not work. Is there a way to figure out a mobs int without my trial and error method such as using a variable? I haven't a math class in years so I'm not sure how to do
1383=[120-X) * 2) +541] * 1.85 * 1.15
Even if this is possible wouldn't that come out as an uneven number which isn't possible as an int stat?

Thanks for any help here!

I'm getting that the 65 INT Marid should be 1384, 1380 for the 66 INT(don't forget to floor after each step).

Only 1 damage difference would just lead me to believe their calculation rounds something funny or something.

[Amele]

the const in question is the calculated result at the point of inflection (compare to delay formulas for your examples)

but what you forgot to do is floor, I think;

floor(floor([(120-65) * 2) + 541] * 1.85) * 1.15) = 1384. the other formula comes out to 1380.

well, no. you did forget to floor but it didn't solve the problem. it is possible that you are past the constant, but by how much I can't say since I've no basis for making an estimate.

back figuring we get a value of 1202.6 for the interior of the term X*1.15 which is.. unlikely. so I suspect that my expectation that we should be flooring after each step is inaccurate.


edit: aha, reverse the order that you apply 1.85 and 1.15 and floor after both steps and you get a result of 1383 for 65INT (748*1.85 = 1383.8)

[nivlakian]

You need to multiply in the proper order and floor after each step.
Given your information, the marid has 65INT.

floor(floor(floor((120-65) * 2 + 541) * 1.15) * 1.85) = 1383

Is there a database somewhere with all the stats of known mobs? Well INT in particular.

I know there was one a while ago that showed the DEF/VIT/AGI/EVA of a bunch of merit mobs... which I just happened to be looking for also... if anyone knows where either one of them are.

Gobli's old calculator site has it, but it's incomplete and probably not worth it to look at it now since we don't face those kind of monsters lately

[cdgreg]

Thank you very much everyone. That has been driving me up a wall for a few days now since I posted it on ls forums hoping to figure it out before I looked dumb on BG . I did not realize I had to floor the decimal. It would be great if there was a database with common mob stats.

[(120-65) * 2) + 541] * 1.15 * 1.85

[(55) * 2) + 541] * 1.15 * 1.85

[(110) + 541] * 1.15 * 1.85

[651] * 1.15 * 1.85

748.65 *1.85

FLOOR

748 * 1.85

1383.8

FLOOR

1383 - Perfect!

we've done the work confirming the gobli formulas to high accuracy but no one has done the grunt work of recreating the ranks for the various and sundry mob families.

some are known to high accuracy (colibri, mamool, etc) others are basically unknown entirely (faeries) and the subset that we know int for is basically not the subset the we know vit and agi for.


given a known level, final evasion, and final defense value, it would be possible to come up with a small number of possible rank combinations for each mob - one of which would definitely be accurate.. but it's time consuming work.

Last question on this topic: is it possible to use a variable to determine int if you know nuke dmg? Or do you need to trial and error it? I'm not nearly skilled off the top of my head to know how to do that step by step.

[(120-X) * 2) + 541] * 1.15 * 1.85 = 1383

[Callisto]

Generally, yes, however keep in mind that there's a chance that the target will have some native magic reduction due to their race, or MDB due to being a RDM or WHM, in the cases like Pots and Weapons sometimes both.

it is possible, flooring in mid step makes it somewhat more difficult because it gets harder to unravel the floor. in practice, you can get close and then try 'known real' numbers until you get the answer.

in this case: 120 - ((1383/(1.85*1.15) - 541) / 2) = X

X = 65.4

obviously, X can't be 65.4, so try 65. then adjust +/-1 if it's too high or too low.

formula would be: your_INT - ((damage / (BONUSES) - V ) / M ) = target_INT.

this assumes you aren't past the inflection point; so don't use it on level 1 bunnies or anything.

edit: this also assumes that all the caveats callisto listed are true. you can control for them and re-work the equation to accommodate them but I don't feel like doing it here (shell is the easiest to handle, figure out the % reduction of shell and apply it in reverse to the initial damage; remembering that shell floors too.) MDB is a little harder unless you already know how much it has.

Ah good point. That's why I choose Marid's they didn't require any target magic damage adjustment.

edit: thanks big thanks amele. you were posting as i was replying to callisto
