The tooltip of the gem just says "3%" which could even work for mages. Does someone has any confirmation if the 3% really only work for melee-dps. If that'd be the case the value of gem would greatly decrease for hunters.

There was a blue post awhile back on this, stating that it's not working for arcane shot currently(but everything else) and that it's being looked into.

So I guess it's not confirmation that it'd work for mages, but at least it shows that it's not only melee dps.

Seems quite clear to me.

Oh.

From the blue poster:
So this seems like it is consistent with the description on thottbot "Apply Aura: Mod Crit Damage Bonus (Physical)" that it increases all physical damage, but does not yet affect magical damage (Arcane Shot is arcane damage with melee mechanics right?).

Arcane Shot is a normal physical (ranged) attack in terms of mechanics, dealing Arcane damage.
Possible outcomes of Arcane Shot:
Hit
Crit
(Partial) block - both hits and crits
(Partial) resist - both hits and crits, I believe.
Immune
Miss

Patch 2.1.2 released on PTR.

"Relentless Earthstorm Diamond: The bonus damage to critical strikes from this metagem now applies to all types of damage, not just physical."

Does that mean i can apply this to my mages gear? Any possible theroycrafting compared to other gems? Since i'm a lazy peon, i'll let the experts do the work.

Though possible, it seems more likely that this is just Blizzards way of saying that it now works for arcane shot as well. They've always had a tendency of vague patchnotes meaning simple things :P

I was thinking that too. But i mean... "all types of damage". Come on, ist just ALL types of damage nor?

The crit damage increasing talents work like the latter, so I would assume the diamond does as well.

And hopefully WF/SS, if it already didn't

Humanoid Slaying has already been determined to work for crits like this:

Base Damage + [Base Damage * (Crit Modifier * Slaying Modifier)] * Slaying Modifier

Thus with Mortal Shots and Humanoid Slaying, it would look like this:

Base Damage + [Base Damage * (1.30 * 1.03)] * 1.03

Just did some testing with a Fine Light Crossbow (Damage = 29-29) and Relentless Earthstorm.

Firing at the Void Conduit at Ultris (rough numbers):

301-302 Damage base
717-718 Damage on Crit

301.5 + (301.5 * 1.339) * 1.03 = 717.3

Tricky part now:

On Dr. Boom:

321-322 Damage base
791 Damage on Crit

Without the Relentless Earthstorm you'd get:

321.5 + (321.5 * 1.339) * 1.03 = 764.9, which is not 791.

However, what really happens in game (numbers fully represented):

321.5 + [(321.5 * 1.30 * (1.03 + 1.03)] * [1.03 + 1.03]

[top] 791.1

Mind you, that damage without Slaying would be:

321.5 + (321.5 * 1.30)

730.5

Taking out the +3% damage bonus you'd get:

321.5 / 1.03 = 312.1

312.1 + (312.1 * 1.30) = 717.83

This would mean that combined together, Humanoid Slaying and Relentless Earthstorm Diamond increase overall crit damage by 10%, compared to not having points in either talent (mind you, this factors in the 3% more base damage as well).

Are you missing a set of parrenthesis on that Eej?

Is it

Base Damage + [Base Damage * (Crit Modifier * Slaying Modifier)] * Slaying Modifier

or

(Base Damage + [Base Damage * (Crit Modifier * Slaying Modifier)]) * Slaying Modifier

?

Cause if it is the first then it would seem the slaying talents do not match their tooltip at all (aka, the "all damage cause to x by 3%" isn't really all damage, but instead just multiplying crit damage by 1.0609).
