% dmg modifiers

General Discussion
so with sets or legendary items when it says +3,000% dmg to a skill....is that an additive percent or straight multiplier??? like if the skill already does 2,000% weapon dmg does it now do 5,000% or does it do 6,000,000%?

neither, it's basically 60.000% weapon damage (2000*30)

that kind of math would suggest that a 100% dmg modifier does nothing...
Yes, they are multipliers.

A 2,000% weapon damage skill increased by a 3,000% set bonus would be a 31X multiplier giving it 62,000% total.

(3,000 / 100) + 1 = 31

right ^-^
Most are multipliers, a few is increases
Rules of the thumb

Orange cube-able powers from legendary items are multipliers

Set bonuses are multipliers

Primary rolls on items (aka x skill does y damage) are thrown into additive damage

Additive damage from all sources is added up and turns into multiplier (example: 25% from falter + 10% from battle rage + 200% from weapon = 235% which equals 3.35 multiplier)

If something is multiplier and it says "increase by 200%" it is a multiplier of 3. Basically, when you looking at the number on multiplier in percentage value, move the dot two slots to the left and add 1 for your final multiplier. More on it by my friend:

[This is accurate as of 2.4.1]

I see these mistakes time and time again...

This is not a guide for calculating your damage, but it does have some general rules you should remember and use.

1. Is your damage bonus additive or multiplicative?

This can vary from class to class and item to item. A simple, but not always true, rule to use is: does the damage bonus show up in your character sheet? It is most likely additive. Do you not see any indication of the damage bonus from your character's stat sheet or profile? Good chance it is multiplicative.

2. Additive does not mean you add the damage bonus to your skill's weapon damage.

An example would be Fury of the Vanished Peak's Seismic Slam damage. It is what we call additive, but we do not add the (100-125%) damage increase on top of Seismic Slam's 620% weapon damage. We still multiply the 620% weapon damage by the 125% Seismic Slam damage increase. Instead when we say additive, we mean you take all of the additive sources of damage bonus and add them all together before multiplying by your skill damage. For instance, you would take FotVP's 125% and add it to Battle Rage's 10% and get 135% total additive damage. If this is your total additive damage bonus, you now multiply this by your skill damage.

I believe Nubtro has a thread out there somewhere that lists most bonuses and what category they fall under. If all else fails, a simple Google query will lead you where you want to be because I guarantee you there is already a thread or discussion talking about the bonus.

3. Damage bonuses are usually listed in percentages.

This is the most common mistake I see. I will see player after player take a 100% damage increase and multiply their skill damage by (*1) and call it a day. 100% increased damage means you are doubling your damage. Doubling your damage means multiplying by 2. If we extrapolate this further...

50% ==> *1.5
100% ==> *2
200% ==> *3
250% ==> *3.5
500% ==> *6
750% ==> *8.5
1000% ==> *11

An easy way of remembering this is simply adding (+1) to the damage bonus when it is in percentage form to get your multiplier. For example, Berserker: Insanity is a 50% damage increase. You take (+1) and (+50%) to get (*1.5). Remember, with percentages you have to move the decimal two places. So 50% becomes 0.5, but then you add that (+1) to get your multiplier.

4. You take each category and multiply them together to get your final damage increase

Your categories are basically each final multiplier you may have

a) Additive
b) Elite
c) Elemental
d-z) Each additional multiplier ranging from Bane of the Trapped to Insanity to Focus to Restraint (remember, these are each separate) to Set Bonuses

-------

Know your class, understand what passives and skills are additive, what are multiplicative. Learn all about legendary gems (like Trapped or Zeis being multipliers, Taeguk being additive).
