Math problems
Heya, I know this title scares away most players, if you haven't been scared away by the title, I need your help!
I am trying to calculate my infernal blow damage, trying to figure out if I should help oak or kraitlyn (I think oak but I want to be sure) I removed all my support gems to make things easier to calc. infernal blow is at lvl 10 which does
Spoiler
36% increased phys dmg
50% of phys dmg converted to fire dmg 125% of base dmg with auras my auto attack does 277-581 phys dmg. I got 1,572 attacks per second. 36% increased dmg 277 * 1,36 = 376,72 581 * 1,36 = 790,16 50% converted to fire 376,72 / 2 = 188,36 790,16 / 2 = 395,08 125% of base dmg 1,25 * 188,36 = 235,45 1,25 * 395,08 = 493,85 Now this multiplied by my APS 235,45*1,572 = 370,1274 493,85*1,572 = 776,3322 chance to crit 5% crit multiplier 150% (I havent taken resolute yet) 370,1274*(1+,05*(1,5-1)) = 379,380585 776,3322*(1+,05*(1,5-1)) = 795,740505 chance to hit 88% (final phys min dmg) 0,88*379,380585= 333,8549148 (final phys max dmg) 0,88*795,740505= 700,2516444 when I use infernal blow (without support skills) I got 196-411 physical dmg, what am I doing wrong with my calculations? edit: I got 111% increased physical dmg from my tree, and another 18% from my belt, and 46,6% from my strength Last edited by Centrius on Apr 24, 2015, 10:01:09 AM

" Your increased phys damage from IB stacks with all increased phys things you get from the tree and otherwise. Say, if you have 50% increased phys damage from other sources, you need to calculate your base damage as 277/1.5 - 581/1.5 and the new damage after increase as 1.86 times these results.

yeh but my ingame dps is less, not more.
if I multiply it with my increased phys dmg from my tree it should even be more. | |
No. The impact of adding increased phys damage gets lower. Sticking with the 50% prior increase (probably on the low side), you are multiplying by 1.86/1.5=1.24 instead of 1.36 in your case.

" Even so, he says his tooltip IB damage is lower than his tooltip default attack damage? That doesn't sound right at all. Edit: Baal, look at the actual numbers, don't just spout platitudes. He reports 277-581 for tooltip default attack damage, and 196-411 for tooltip IB damage. OP: are you sure for that second number, that's not just "physical" damage? You should have a physical and fire line separately on IB's tooltip. Edit: No, nevermind, OP already said physical damage. So all of these numbers are right.

The point is, you have to start with your Base Damage, not your Default Attack Damage.
The Default Attack already factors in a bunch of Increased Damage, and the Increased Damage bonus from Infernal Blow adds onto that. You are currently stacking them multiplicatively, which leads to a higher value. You need to run down your tree, tally all sources of Increased Damage, check your Strength value, any multipliers from gear. Take the Base Damage as listed on your weapon plus any flat bonuses from gear, and Convert 50% Phys to Fire. Multiply the Phys portion by any applicable modifiers. Multiply the Fire portion by both Elemental and Physical modifiers. Increased/Reduced is additive, More/Less is multiplicative. x% Base Damage acts as a More Damage multiplier.

well my increased phys is higher then 50%, I've updated my post
I'm gonna recalc some things, thanks for all help. Will be updating soon in general, oak is better most of the times, am i right? (18% increased phys, vs 8% IAS?) Edit: Min wpn dmg 98 Max wpn dmg 205 min fire dmg added 9 max fire dmg added 20 increased phys dmg 175,6 New Min 172,088 New Max 359,98 Infernal Blow 172,088 234,03968 (172,088*1,36) 292,5496 (234,03968*1,25) min phys dmg = 146,2748 (292,5496/2) Max Phys 489,5728 611,966 max phys dmg 305,983 min added fire dmg 9 max added fire dmg 20 Min fire 155,2748 Max fire 325,983 I know it looks a bit chaotic, Open office doesnt copy/paste as well as i hoped, but my damage still aint the same as it truelly is ingame. What am i doing wrong? Last edited by Centrius on Apr 24, 2015, 10:38:10 AM

You still apply your physical damage increase from IB multiplicatively.
I have phys_ib=phys_auto*(1+ipd_base+ipd_ib)/(1+ipd_base)*conversion*mult_ib using your values for the minimum: phys_auto=277 ipd_base=1.756 (your damage increase) ipd_ib=.36 (increased phys from ib) conversion=.5 (fire conversion from ib) mult_ib=1.25 (more value from ib) and get phys_ib=195.7 (=196) as in the tooltip. With Oak we arrive at 207 (by increasing the first bracket by .18). For the Kraityn effect, we need to know your current ias modifier. |
