One more follow up Q:
Does this mean, when using +% ele damage affixes, rings, OHs, Ammys, etc That +min affix or +xx-yy affix is better than +max affix? Or, in the case of OHs, two with the same average damage, but with different min/max, the one with the greater min is better?
Also, you say +%dmg affix is on the tooltip for the physical damage, is +min/max also?
Yes, items with higher MIN damage are currently better than their lower min higher max same dps counterparts if you use other items with the "Adds x% to <elemental> damage".
One small point of clarification - it uses all of your minimum physical damage, not just what is on your weapon. So add in the minimum physical from your jewelry and source/mojo as well.
This is 100% true, however the reason it is true is that all other items that have +min +max or +xx-xx damage on them also add to your base weapon damage without being represented in the weapon's tooltip.
If you have a 100-200 damage wep and wear a ring with +15min damage and an ammy with +15max damage your wep will actually have 115-215 damage.
And what about skills that deal elemental damage? For example Rapid Fire deals physical damage, it gets the bonus damage from the affix. But Withering Fire rune turns Rapid Fire into fire damage skill. Does Rapid Fire still get the bonus from the affix? Tried to test, but it's very hard to tell with the 5% Frostburn Gauntlets I bought for 90k for the purpose of this test :)
The Affix adds to your base weapon damage and, therefore, increases the damage of every single skill you have that bases its damage on your weapon. The element of said skills do not matter.
follow up questions:
does a weapon without +elemental damage(but with what i'm assuming is physical +max-min dmg) gets a bigger boost from this affixes ? (assuming yes.)
For a full explanation with examples of how this interaction works, please read my response on page 3 of this thread.
can that extra damage crit and trigger wizard talents/snares? how does this extra damage behaves with skills ? is it transformed into the elemental kind of the skill. does it apply individually as fire/cold/arcane etc from weapon damage skills ? can this small extra damage in any situation trigger talents like wd damage reduction on poison, wizard extra dmg deal on fire, snare on cold, slow on arcane ?
The extra damage behaves exactly like the elemental damage you find on weapons all the time. It will be turned into the element of your chosen spell.
If your spell has no element it will use the element of your HIGHEST elemental damage (usually the affix on your wep).
If your wep is an all physical wep and you use a skill without an element, it will use the element of your "Adds x% to <elemental> damage" affix to determine which element to do.
The extra damage is NOT separate from your weapon and therefore can't proc things or do much of anything outside increase your dps.
