Title: Poison Damage Formula for Fire/Poison Magician
Written by: ThunderStrike Edited by: Ayumilove

Thanks to Silencer I now know the formula for damage per second to be 1/(70- Skill level). The original purpose of this thread was to find a compact formula for the damage poison does at each level. I’ve now gathered the percent per second damage for each level of poison. Although anyone is welcome to post their damage on something for accuracy’s sake. Here is the data for level 1-30, which holds true for both Poison Myst (Poison Mist) and Poison Brace (Poison Breath). Although the name was changed back to Poison Breath in .38, brace sounds better, so I still call it brace.


Level / Per Sec / Total
1 / 1.448% / 5.792%
2 / 1.469% / 5.876%
3 / 1.491% / 5.964%
4 / 1.512% / 12.096%
5 / 1.537% / 12.296%
6 / 1.563% / 12.504%
7 / 1.584% / 19.008%
8 / 1.612% / 19.344%
9 / 1.638% / 19.656%
10 / 1.666% / 26.656%
11 / 1.694% / 27.104%
12 / 1.722% / 27.552%
13 / 1.753% / 35.060%
14 / 1.785% / 34.700%
15 / 1.817% / 36.340%
16 / 1.851% / 44.424%
17 / 1.886% / 45.264%
18 / 1.922% / 46.128%
19 / 1.960% / 54.880%
20 / 2.000% / 56.000%
21 / 2.040% / 57.120%
22 / 2.082% / 66.624%
23 / 2.126% / 68.032%
24 / 2.172% / 69.496%
25 / 2.221% / 79.962%
26 / 2.271% / 81.741%
27 / 2.323% / 83.689%
28 / 2.379% / 95.153%
29 / 2.438% / 97.52%
30 / 2.500% / 100.000%

Most of the data came from screen shots, all of it was from high HP monsters (From DTs to Bonefish, and I think some was thanatos).

But, there might be a flaw in the data. If you have a low level of brace, myst, or comp, poison something and count the number of times damage appears (if using myst, lure it out of the myst so it can’t get repoisoned). The number of times is Duration + 1. I used Duration to multiply from % per second to total, so it may be wrong in the right column.

But that actually makes quite a bit of sense. In my avatar picture, max brace does 1062 damage per second to a bonefish. 1062* 40 = 42480, 20 less than the 42500 bonefish have. The extra hit is to account for rounding.

As such, I am not sure anything about it. I do not know if it does damage that is counted always even on lower levels of poison (it does appear though), or if it always appears and just does damage when the damage per second got rounded down. Or what ever else.

Extra Information
Fire Demon has the same formula for poison attack.

    Kachi, under per sec, it’s the total % of the monster’s HP it takes per second. The total column is how much of the monster’s HP was taken away after the poison wears off. So if you had max poison, it would theoretically take away all the monster’ HP. I think it’s like this…
