Casters will love this. Hopefully uptime will be big enough.

Comment by Sam97

Oh yeah , this is strong bonus . Seems like it's time to get some haste trinkets .

Comment by perculia

This is one of ~~five~~ four new legendary meta gems coming in 5.2. It is a reward for completing The Crown of Heaven as part of MoP's legendary questline:

Capacitive Primal Diamond: +324 Crit & Chance on striking with a melee attack to gain Capacitance. When Capacitance reaches X charges, you will deal a Lightning Strike to your current target for 100 Nature damage.
Courageous Primal Diamond: +324 Int & Chance on casting a helpful spell to make your next spell cost no mana.
Indomitable Primal Diamond: +324 Stamina & Chance on being hit by a melee attack to gain a 20% reduction to physical damage taken for 15 sec.
Sinister Primal Diamond: +324 Crit & Chance on dealing spell damage to gain 30% spell haste for 10 sec.
Tyrannical Primal Diamond: +665 PVP Power & +775 Resilience. In build 16503 this is no longer legendary!

Blizzard confirmed on 7/29 that these meta gems will work in Patch 5.4 Siege of Orgrimmar helms: Source

This is like proc'ing a mini bloodlust.

this is too powerful.

Comment by Ambellina

A quick Google search shows the spell that this procs, Tempus Repit, is a combination of two Latin words meaning "time crawls" or "time creeps"; and since this increases your spell casting speed rather than hinders it, one can only assume this little thing will change time itself and plane you out, so to speak, for the duration of the proc and as we've seen with spells similar to this in the time sense, I hope this will have a neat little clock/fade type visual with it also, giving that extra legendary show off feel since meta gems are not visible unlike entire weapons.
This also has the same spell haste buff (30%) as Time Warp, though a quarter length duration, making this essentially a mini personal Hero/Bloodlust proc.

Comment by Surbmonster

I want to know what the softcap on this is though before I get too excited. Something this powerful will have a hidden line in the coding that prevents it from happening too often. I would not be surprised if this is limited to once every 60 secs. 30 if we are lucky. And that may prevent it from being nearly as powerful as first advertised. Blizz needs to get on this in a blue post and say what the frequency of these procs on all these gems are supposed to be. I am still head scratching on why the primary stat given is Stam. Really? Stam? So I can still get 1 shot by any basic melee in a dungeon as a clothie? GTFO Blizz and give me some Int.

Comment by Janettie

These are great gems, but I am confused as to why they all have stamina, instead of strength, agility, and intellect.

Comment by rodalpho

Proc rate is as follows.

Sinister Primal Diamond – 1.18 base RealPPM on damage/absorb of harmful or periodic spell. No ICD.
- That base proc rate is multiplied by an additional coefficient:
0.761 Arcane
0.302 Fire Mage
1.387 Frost Mage
0.625 Affliction
0.598 Demonology
0.509 Destruction
1.891 Elemental
1.872 Moonkin
0.933 Shadow
1.000 Anyone Else

Real PPM (RPPM) description:

Comment by oscarucb

At the reported 0.84 RealPPM with a 10 second duration, this works out to an average uptime of 14%.

Assuming uniform sustained dps and a perfect scaling of dps with haste (ie no GCD capping) this implies a maximum overall dps improvement of 4.2% for the proc. If your main nuke often skirts the haste hard-cap when haste buffs are up (eg. Elemental Shaman) it could provide considerably less benefit.

If this gem is indeed meant to replace, instead of augment, our current dps caster meta gem Burning Primal Diamond, this seems like a lackluster tradeoff at best. For most caster dps classes intellect is highest in the stat priority and crit is dead last (ie losing 216 intellect to gain 324 crit is probably a loss for everyone, except maybe boomkins). The haste proc may have a slight edge over the 3% increased crit damage buff, but is it enough to compensate for the loss in primary stat?

In summary, seems like more of the same disappointing "legendary" vendor garbage we've come to expect from this expansion.

EDIT: The updated RealPPM proc rates are posted here and are spec-specific and range from to 0.302 ppm to 1.891 ppm. This implies a ridiculously wide range of expected uptimes from 5% to 31.5%, based on your spec. Remains to be seen how this is going to pan out in real encounters.

Comment by Clebane

You can buy extra Sinister Primal Diamond from the vendor Blacktalon Quartermaster located in the Tavern in the Veiled Stair for 5x Primal Diamond.

Comment by villainae

Once you collect 20 Secrets of the Empire and 40 Trillium Bar, you will get a quest to kill Nalak and siphon his essence. Afterwards, Wrathion will ask you to meet him on the top of the mountain like in the 5.0 quest, and reward you with one of the legendary meta gems. The quests to collect 12 Titan Runestone and kill Lei Shen appear to just be follow ups.

Comment by 420psilo

Just in case there is another curious Paladin like myself that Wished they too would be able to benefit from this mini Blood Lust. Both Prot and Ret would love them some Haste. I took the time and the 5 primal diamonds do to a little research and Development, but alas it is Spell haste and not the Melee Haste that Sanctity of battle needs. So unless your into having 0.9 sec FoL cast times. or A 6 sec rez cast time don't bother. Save yourself the 5 primals diamonds. I'm sure this will be downrated to all hell but I can't be the only one wishing this could be used by my ret paladin. I had searched the internet before hand and nothing had come up about it. So i decided to test it out myself and in conclusion it appears that the Capacitive Primal Diamond is the obvious way to go. Hopefully this message will reach others who may be dumb enough to try and use this in their Melee DPS meta.

I admit my faults so that others may learn from the error of my ways. plz be gentle with the downvote button.

Comment by MoonslayerLB

looks like there's a minimum iLevel requirement on the helmet to gem, i tried to gem it in my 496 helmet and got the error message "The item is too low level for that gem." comments on wowdb also report that 2/2 upgraded t14 helms at 504 ilevel also won't accept the gem.

Guess i'll have to wait for a Throne of Thunder helm.

Comment by shadra

I'am able to put this gem to my 517 helm.
I think requirement is 502 "base" ilvl (since gem doesn't fit on 504 upgraded helms), which translates, either t14 heroic helms or any kind of throne of thunder helms. (or 522 craft helms)

Comment by Mante

Can currently only be placed in a helm of 502+ ilvl.

I ticketed a GM about this and was told to report it as bug. Hmm.

Comment by Joe703

Do you need to complete the questline below before obtaining the Sinister Primal Diamond?

sigil of wisom and power questline
The Strength of One's Foes

Comment by HarskGaming

Quick question: Does this proc stack with Heroism/Bloodlust?

Comment by Hulaine

~~Can anyone confirm if these meta gems work in Challenge Modes?~~

Edit: Checked it, apparently they do NOT work.

Comment by Pootie

If you use WeakAuras like I do the buff is called Tempus Repit and is a 10 second buff. Hopefully I'll save some folks some time.

Comment by Arikara

This gem is a Miniature Bloodlust Generator.

Comment by Aldones

You can have multiple types of Legendary Primal Diamonds. Hybrid classes can have a different gem for each spec.

Comment by Nyteyes

From a hotfix dated December 16:

Battlegrounds and Arenas

Legendary Metagem effects (Capacitive Primal Diamond, Courageous Primal Diamond, Indomitable Primal Diamond, and Sinister Primal Diamond) should no longer have a chance to activate while in an Arena, Battleground, or Rated Battleground.
