Diablo® III

OK, so I have a gem in my hand. It will increase my weapon's damage by 10-20.

I socket it, and now my weapon's damage has increased by exactly 10. What happened to the rest of the range?

If a gem increases a weapon's damage by exactly 10 (10-10, if you prefer a range), then it will increase the minimum damage by 10, and the maximum damage by 10.

But, when I socket a gem that has a wider range, namely 10-20, it does exactly the same thing: increases the minimum damage by 10, and the maximum damage by 10.

Now, I accept that my math skills are probably not as good as the math skills of the computer scientist wizards who programmed Diablo 3, so perhaps someone can explain this math in remedial terms to me?

Thanks!

Up.

Depends on the speed of the weapon swing also
damge vs dps etc

10-20 increased damage is essentially 10 to minimum and 10 to maximum

Not 10 min + 20 max to equal 30

10-20 increased damage is essentially 10 to minimum and 10 to maximum

Not 10 min + 20 max to equal 30

Yeah, I gathered that. I suppose it's just an inaccurate label then. 10 to minimum and 10 to maximum would be 10-10 increased damage. Or, in easier-to-understand terms, +10 to damage. Kind of annoying to those who grasp basic mathematics, no doubt.

A weapon with 10-20 damage, has an average damage of 15. With the 10-20 damage gem added it would be 20-30. The average would be 25.

An increase in average damage of 10.

Precisely. An increase in average damage of 10. Not in average damage of 15, which is what you get when you add 10 and 20 together and divide by 2. That's why the gems should really be labelled +10 increased damage and not +10-20 increased damage.

I assume they did it the way they did in order to make it easier to understand for noobs, but in fact I think it has the opposite effect, especially with Blizzard spoonfeeding you your average damage right on your character screen.

The end result is that it is both confusing AND factually incorrect.

It's more complicated than that but it's all explained here:
