How does main stats increasing damage actually work?

I’m curious as to the legitmate inner workings of say Dexterity increasing the damage of Monks and Demon Hunters? When you hover over the stat name it says something about each point of blah blah increases your damage by the amount of your stats as a percentage. So I have roughly 17.5 k Dexterity on my Dh with my paragon, gear and augments so it says “increases damage by 17.5k%” but is that really the case? I’m so confused by that can someone please explain this all to me?

Easy way to see these is to use d3planner,

Like, 95%+ it’s reliable. Load your character, mouse over damagae section on your main source of damage skill. You will see several multipliers shown of how its damage is increased.

And yes, it does work like that. 17500% increase in damage, so that’s x176 damage to you.

How do I upload my Dh into that?

Are you on d3planner right now? Click import/save, pick your region, type your bnet id, click search, click id, go to skills/effects tab. Everything is pretty self explanatory. Putting paragon points, putting the right cubed item, changing stats in gears if you want to theorycraft, etc.

Okay I got it working, but still I have no clue how Dexerity increasing my damage works… My Dexterity is 17,794 and says it increases by that much as a percentage, what’s the damage source that it supposedly increases? Is it my weapon(s) Cuz my weapon damages are over 3k and 17k multiplying those two equals 51 million lol it’s all confusing

In skills/effects tab, you’ll see HA at the top. If you mouse over ‘damage’, you’ll see all kinds of multipliers listed. On ‘formula’, you’ll see x(number). Below it you’ll see ‘Dex: 17,794%’. What I do is, I try to figure out what each x(number) is referring to. 17,794% is 177.94. But because you start with 100%, 17,794% increase in damage becomes x178.94, which you will see on ‘formula’.

Crap. I think I read your post wrong. On ‘formula’ you’ll see [weapon]. Everything in D3 starts with weapon damage (which I think was one of the good thing that was implemented in D3). Damage source that those multipliers increase is your weapon damage. And no, as I said, not x17000. It’s in %, so /100. It’s x178.94 from main stat multiplier.

Knows math and %’s…I always sucked at it and looks more baffling than Greek to me.

It’s not very straight forward since the in game tool tips don’t list how the formula works and some things are additive and some are multiplicative.

But yes, dex does increase your damage by 1% per point. It starts with weapon damage and factors in the skill damage percentage (you may hear people say dibs - damage increased by skills). This bucket includes skill bonus damage on items and some damage bonuses from other sources like some leg gems, some passive, etc, so not terribly straight forward. That’s the reason people may say something is dibs as a bad thing, since if you already have 400+ percent in your dibs pool, adding 10 to it to go to 410% is actually only a 2.5% increase instead of the 10% the item or skill is claiming. This is as opposed to the 10% being a separate multiplier, boosting our 400% to 440%.

The other thing to be aware of is that the more mainstat you have, the less impact adding a point of dex will have. If you have 10k dex, adding a 500 dex augment is increasing your dex by 5%. However if you have 20k dexterity, adding that same 500 dex augment is now only a 2.5% increase in dex and therefore damage.
