What is this all about?
As has been pointed out before, most procs from trinkets have an internal cooldown which prevents them from chain proccing. Often, the cooldown is 3 times the proc duration, but some are longer, and some procs thad do do not give a buff for a certain duration incur a cooldown as well.
As the value of an item may vary greatly, I'd love to gather the info about those trinkets to make comparing them somewhat easier.


How does a proc with a cooldown work?
If an item has a proc that lasts 15 seconds and has a 45 second cooldown, that means the following:
If the item procs, you'll have the proc up for 15s and you will not have it up for the 30s after the proc faded. After those 45 seconds (counted from the start of the proc), the item can proc again with the listed chances.


What happens if I have several trinkets with procs?
From personal testing, they seem to act independently. I could have both trinkets proc at the same time, or a few seconds apart, and their buffs stacked. (This was with Shiffar's and Sextant, there are some reports from items seemingly sharing their cooldowns?)


Are there some general guidelines?
Few rules are without exception, and new items can always be different from everything before. However, the following held true for everything so far.

- Weapon procs of the "Chance on hit: ..." type usually have no cooldown and can chain proc.
- Weapon enchants of the "Chance on hit: ..." type usually have no cooldown and can chain proc.
- Procs that are set bonuses from item sets usually have no cooldown.
- Most meta gems do not have a cooldown and can chain proc.


How does Spellsurge work?
The weapon enchant Spellsurge (Spellsurge) may be a bit of an exception: It has a 10s duration, 50s cooldown, but it stacks with spellsurge enchants of other people in your group. In a group of 5 casters, it might eventually be able to stack with itself, but that is just speculation.

Currently, I only have items listed that I've had the chance test myself. I really appreciate any further information about other procs, from casters and physical damage classes alike.

I'd love to get as much information about procs as possible to make the available gear easier to compare.

Dragonspine Trophy - No internal Cooldown (based on PTR Tests as i dont have one on Live)

 

Zoro

Hourglass of the Unraveller from BM has an internal cooldown.
3x buff duration seems a bit longer than observed, but I suppose that might be observer error.

 

kirr123

Fathom-Brooch of the Tidewalker http://www.wowhead.com/?item=30663 has a 45 second cooldown. Procs about once per minute with the 15% procrate

 

delany

It is not 100% to the topic, but has anyone information about the proc/proc rate of the new meta gem with the haste effect on it?

 

◊ tenshi

Lesser Spell Blasting proc from Spellstrike set doesn't have a cooldown according to thottbot, and this matches my observations. I've had this buff chain proc, and even refresh the previous proc.

 

PsiVen

From the PTR, Tome of Fiery Redemption (paladin class trinket) - http://www.thottbot.com/test/i30447 - +260 spell damage for 15s, 15% proc on any spell, 45s cooldown. Not positive; it might be 1 minute.

 

Avin

I can confirm this, have been using it for many weeks on live and it can proc at any time.

 

Orestus

2 piece Malorne Feral set bonus (Chance to gain 5 rage/20 energy on hit) has no cooldown, has procced consecutively many times for me on Live.

 

dukes

Bangle of Endless Blessings, has a 45 second cooldown afaik (triple duration).

 

banaj

As the other posted said, there's no hidden cooldown on this.
It can chain and overwrite the proc (procs an awfull lot as well).

 

BeeLz

Nvm, I'm an idiot

 

Nite_Moogle

Not a trinket but: Windfury Weapon, 3 seconds shared across all ranks as of 2.1.

 

sylveni

Quagmirran's Eye has a 45 sec cooldown, (from the spell haste thread, specifically, here)

Voidheart 2 piece bonus has no cooldown, I've had the buff refresh itself, as well as the shadow and fire buffs up concurrently.

 

Umph

Definitely longer than 3x buff duration I'd go so far as to say it's on at least a minute cooldown, possibly 1.5 to 2.

 

Zarat

I can confirm the 2 piece Voidheart set bonus having no cooldown whatsoever. Multiple times of having not only both effects up but having one of them refresh their duration. Sometimes back to back to back.

 

thebuddha

I'm kind of annoyed that they don't list these cooldowns on the trinkets.

In some cases they do like "This effect can't occur more than once every x seconds"

http://www.wowhead.com/?item=28108

Obviously, I see why they put these CDs to prevent a trinket from being too powerful, but I just don't follow the design philosophy in tricking people into getting items that are worse than they initially appear.

 

Kavan

Wrath of Cenarius (http://www.wowhead.com/?item=21190) - no cooldown

 

• Falk

2-piece Feral T4 (Bloodlust effect, +20 energy / +10 rage) has no cooldown. <3 for proccing 80 energy in the space of 6 seconds once.

Edit: Reread the first post. This is on live currently... haven't tested on PTR to see if anything's been changed.

 

Tanoh

Yes, that would save us a lot of headache. They really should list the cooldown of "Use:" items in the tooltips too.

While I'm too lazy to check it up on wowhead, I do think that the only things that have a listed cooldown are things where you kill something, like the mushroom. To trigger it you have to kill a worthy enemy and it always triggers if the cooldown is off, things that have a chance to trigger an effect don't list the hidden cooldown.

 

Incoherence

Yeah, that would be really nice. I remember discovering myself that Bangle of Endless Blessings had a proc cooldown and being relatively irritated by it.

I'm also curious if this is something that can be data-mined... we can data-mine exact proc rates (even if they're not listed on the item or if they differ from the one listed on the item), but can we data-mine the proc cooldowns?

 

Zoro

There was a thread devoted to this in the Class mechanics forum, there were people in there reporting 4x second refreshes.

 

mek

To be fair, it's no less deceptive to implement a hidden cooldown than it is to hide the chance of proccing the effect in the first place. Spellsurge is a great example, as we can see how it was originally intended vs. how it was implemented: 3% v. 15% and 30sec cooldown. Either way we can say "chance on proc," but the latter procrate w/cooldown is probably much more appealing than the former... despite the fact the cooldown is being "hidden."

 

Brissa

Which makes you wonder why they feel this bizzare need to hide stats all together.
If certain stats show up in perfect clarity why dont all?

There is no valid explanation as to why "Str: +41" is ok but "5% chance on hit to do 500 damage" isnt ok.

 

mek

I think the answer is that they began concealing procs due to the PPM mechanic, which is very confusing and doesn't translate to any simple description; this carried over into concealing newer caster-oriented procs, which did have straightforward proc rates, somewhat illogically. Certainly it's somewhat dumb in its current state.
