Your problem is maxroll
It’s littered with bad info.
So is the character screen in d2. As you can do more actual damage when comparing 1 set to another, but it does less damage on character screen compared to the other.
Actual damage is a function of your skill damage and your enemies resistance amount to your skill type.
As an example, if your lightning skill does 100 damage and your opponent has 80% lightning resist, you will do 20 damage
If your lightning skill does 80 damage and your opponent has 60% lightning resist, you will do 32 damage.
32 > 20
Then that damage is multiplied by how many times you can cast your skill per second. That will give you your “dps”.
So the actual damage from self wield infinity is higher because -to enemy lightning res. Am I right?
