Runes of Magic US / AU

After following Hipocrates' train of thought, I have found out how to calculate char screen damage. The issue of having more damage on char screen then I was able to calculate comes from the fact that damage multiplier skills/buffs fall into two categories.

Global Multipliers
Follows normal rules. Take your on screen damage and multiply by the % change to arrive at your new on screen damage. Nothing funny here.
Note: These ONLY include Weapon Masteries, wd/s passive dmg Secret Agreement, and the warden skill "power of the oak"(if you find another reply to thread or send personal message on forums/in game).

Standard %Multipleirs
Seperate your weapon damage (here weapon damage includes your rune) from your "bonus" damage (pants, chest, set bonuses, anything else that adds + X dmg such as ribs). Apply these % change to only the bonus damage, add that to your weapon damage, and apply the % change a second time.

Before you can attempt to calculate your own damage, you must first figure out what items you use that are global, and which are standard multipliers (thus far only passive increases and power of the oak are "global" so this is quite simple).

Here's a small data sample comparing Power of the oak (15% increase, global multiplier) vs Tambourine (15% increase standard multiplier). The first 2 rows are with only my weapon equipped and nothing else, while the 3rd and 4th rows show the damage with pants, chest (and set bonus) factored in.




The formula forMELEE char-screen damage looks like this:

[ (weapon damage + rune) + (chest + pants + set bonus + damage food + etc.) x Standard%Multipliers ] x Standard%Multipliers x GlobalMultipliers

See Char Screen Damage Calculations for ranged weapon damage (they are not the same, they just look similar).

Yes,your standard %multipliers appear twice. Globals apply to everything only once, where as standard % multipliers get applied in 2 places. In rows 1 and two, the chest/pants/set bonus are 0, so tamb vs power of the oak yield the same results. In row 4, using StandardMultipler tambourine, the calculation looks like so:

[ (19243.0 weapon damage + 205.2 rune damage) + (600.5+350+554.4)x1.15(FIRST tamb) ] x1.5 (global weapon mastery) x 1.15(SECOND tambourine) = [21178.835] x1.5(weapon mastery)x1.15(Second tambourine) = 36533.49 Exactly what the table shows.

Another calculation using standard multipliers Juicy Spare Ribs, Feral Leader, tambourine, and gloabals power of the oak and weapon mastery.

[ (19243.0 + 205.2) + (600.5 + 554.4 + 350 + 340)x.1.12(first ribs)x1.15(first tamb)x1.5(first feral) ] x 1.5 (global mastery) x 1.12 (second ribs) x 1.15 (second tamb) x 1.5 (second feral) x 1.15 ( global power of oak)
= 76 693.9 .......char screen says 76 693. The difference is simply from rounding the game does somewhere. If you attempted to perform a similar calculation without using Standarrd vs Global Multipliers, your calculated number would be much smaller then the one shown on your screen.

If you find any skills that are global buffs (they give you EXACTLY the % they say, regardless of what buffs, or bonus damages you have), please post it in this thread.

New Information: Unequipping my chest, Feral leader gives exactly the damage increase it is supposed to give -- 50%. And so does tambourine. This eliminates a damage rune as a source of concern as it was still in my weapon despite both buffs yielding correct results.

This leads me to the conclusion of
1) the chest itself is where the problem is or
2) the set bonus is the problem
3) both cause problems

After realising this I re-equipped the chest piece, unequipped my helmet (giving me the chest bonus damage but not the set bonus) and learned that without the set bonus, feral leader still yields more than a 50% increase.

So far I have learned that chest pieces, with the additional damage increases, will mess up certain skills (like Feral Leader and tambourine) while other buffs (like power of the oak) still function properly.

Edit2: I am certain that damage set bonuses also affect feral leader. Equipping my helm completes a set bonus of 300 damage. With passive 2h weapon damage, and feral leader, I should gain 300 *1.5 * 1.5 = 675 damage. But when I do so, I go from 44 794 damage to the original posts 45802 damage. In other words, I gain much more than the expected 675 damage. When Feral leader is not active, I gain the expected 300 * 1.5 = 450 damage on char screen.

On a champion rogue, I equipped 2 identical vendor daggers, 619 damage. The Mainhand had 619 damage, the offhand 457. The extra ofhand damage is from the elite skill Runecraft-Haste. It started at level 15.

The expected main hand damage fromplaying tambo is 619 * 1.15 = 711.85. That was what it was, regardless of whether an offhand was equipped or not. Since the offhand was a little over 7/10 of the damage of the main hand, if it affected the gain from tambourine, it should have been noticable. After all, you're posts suggest that a mere 662 offhand damage accounts for 1.3k missing pdmg after tambo is played somewhere. But this is not the case. So offhands don't change anything, although it was a good idea.

I have recently figure out the exact calculation for char screen damage (rounding errors aside). The First post and name of thread have been adjusted accordingly. If someone can perhaps come up with a better explanation after reading (and understanding) the calculations, please feel free to post it so the information is easier to read.

Also feel free to translate for the other languages, since I have no idea if they have this information or not.

Figuring this out has made me feel quite accomplished, even if no one but me cares about it /flex

I will start a list of category B damage multipliers, as defined in the first post, here..please feel free to add
*edit* its starting to seem like i should be listing category A's instead of B's....might be a shorter list lol.

[b][size=14]KNOWN CATEGORY B MULTIPLIERS:[/size][/b]
tambourine
Feral leader (wd/w)
Damage food ---note:tooltip of lvl 85 pdmg food reads "(pdmg+340) x 12% + 340" -- DON'T ADD THE LAST 340 ITS WRONG. just use formula listed on 1st post using 340 as a bonus dmg value
Morale Boost (wd/s)
Energy Absorb (wd)
Holy Illumination
Suicide Advance

Your statement about ribs is false. See attached Screenshots, first without, and second with ribs. Nothing else changed. Even unequipping chest and pants, your method of calculation fails. Test it on your own char values. By your own calculations, 31385 base damage should result in:
(31385 + 340) x 1.12 = 35532.
Clearly not what my screenshot shows. If you disagree, perform the math on your own char values, post the screens, and we can discuss what else may be affecting the calculations.

As for druffbaum figuring this out, while I wouldn't be surprised if he did, I saw none of his posts explaining this. If you know the post (or remember the forum topic) please link, so I can compare with my findings, and give credit where credit is due. The only posts I have found regarding damage are damage DEALT FROM SKILLS. The formula involving the attack-defense ratios as well as how skill damage interacts with weapon dps. I have not found/seen any posts explaining how char screen damage is calculated. I will however, mention that searching via google translate yields many pages that say "google translate cannot display this page, click here to return", which may explain why I can't find the information.

The fact that your calculations for ribs are incorrect is what fueled my exploration of this formula.

Thanks for posting. The link you provided would have been useful a month or so ago; I wish someone, or yourself, had responded earlier. I had begun to suspect that the number of "global" buffs as you describe them was short, since every class seemed to have skills that yield a greater increase than what they should. To make things less confusing I'll update the first post, where global multipliers include masteries, and power of the oak.

Note: if you have some buffs on, then want to calculate what your new damage will be with an additional buff, you can't simply do (current damage x 1.12) to get the new number. You need to factor in all the current additive damage bonuses (chest, ribs etc.) to go from current --> new values, since the 600 dmg your chest gives will now give "more" due to the inner multiplier. In otherwords, it might be easier for most people to just start from scratch then to try and jump from numbers based on 4 buffs to numbers based on 5.

The difference in the bow/xbow damage calculations is interesting. It says that additive damage like chests, set bonuses and such, yield a smaller increase in damage compared to that of melee characters. Couple that with how damage of ranged skills is not calculated solely on weapon dps, it explains largely why scouts gain so little damage with cooldowns compared to other melee classes.
