min dmg is useless i know, but other 3 mods are still nice.
There are two things you need to be aware of:
1. Bug with min/max dmg
If you socket your armor with a jewel that does both +min/max dmg and increased enhanced dmg (ED) a bug arises where the %ED is only applied to the min or the max. For example, if you have a 40% Enhanced dmg jewel with +15 max damage the ED will *only* apply to the max dmg and not the minimum damage.
If you put the jewel in a weapon though, the damage it calculated correctly.
2. Where you place the item matters
Physical Damage is calculated according to the following formula:
[wpn dmg x (1 + %ED on weapon) + min/max] x (1 + %str bonus + %ED off weapon + %ED from skills)
As you can see, there are two types of ways the game views %ED - on weapon or off weapon. If you place your jewel in a socketed weapon the %ED is considered "on weapon". On the other hand if you place it in your armor it is considered "off weapon".
This makes a considerable difference in the final damage done. Lets take an example of a weapon that does 100 max damage, and figure out how much that max damge would increase with a 40% ED jewel in either a weapon or armor on a character with 100 strength and no damage enhancing skills.
In a weapon = [100 x (1 + .4) + 0] x (1 + 1 + 0 + 0) = 280 dmg
In armor = [100 x (1 + 0) + 0] x (1 + 1 + .4 + 0) = 240 dmg
The difference is even more noticable if you are using a skill that increases your damage like concentration of fanatacism. Lets perform the same calculation but this time with a 200% increase in damage from a fanaticism aura:
In a weapon = [100 x (1 + .4) + 0] x (1 + 1 + 0 + 2) = 560 dmg
In armor = [100 x (1 + 0) + 0] x (1 + 1 + .4 + 2) = 440 dmg
On a side note, you can actually get more benefit from +min/max dmg jewels than you can from %ED jewels when you socket them in armor if you are running a dmg enhancing aura. For example, consider the following math without 200% dmg from fanatacism:
40% ED = [100 x (1 + 0) + 0] x (1 + 1 + .4 + 0) = 240 dmg
+15 max = [100 x (1 + 0) + 15] x (1 + 1 + 0 + 0) = 230 dmg
and then with a 200% fanatacism aura:
40% ED = [100 x (1 + 0) + 0] x (1 + 1 + .4 + 2) = 440 dmg
+15 max = [100 x (1 + 0) + 15] x (1 + 1 + 0 + 2) = 460 dmg
Of course the %ED jewel applies to both minimum and maximum dmg while the +15 jewel only applies to max damage, but the math continues to grow with the more %ED skills you have.
