Apologies if this was covered elsewhere, but I couldn't find it here, and Wowwiki didn't give the specifics.

Can anyone detail the proc rate or how WoW calculates the chance or occurence of a druid's Omen of Clarity? I'd assume it's like Crusader, but more PPM, but then again, it could vary by form. Thank you in advance for your input.

1 PPM is the number I've seen tossed around.

It used to be 1 ppm, I can't confirm it's stayed the same since it got moved to the resto tree though.

5 PPM or close to that. Its neither 1 PPM (and has never been as far as i have known the ability, its too low) nor 8 % since its PPM based.

Edit: Also, the procrate is cut in one-third for Swipe since its an AOE ability.

It is currently either WAY more then one PPM or a flat %.

Thanks for the replies. By the way, if it's 1PPM, that's a 1/60 chance of it proccing per attack in cat form, and a 2.5/60 (1/24) chance per attack in bear form. The reason why it might seem more is because it can proc off instant attacks, so in reality with a cat spamming Shred, it might proc 2-3 times per minute.

It's pretty much the same as MS warriors and Hemo rogues with Crusader.

In cat form, farming mobs it goes off 1-2 times per mob almost. 1PPM is way too low for that.

Do you frequently begin combat against a new mob with OoC active? I've found that when I engage a mob, with OoC active, it has an extremely high chance to proc again within the first 5-8 seconds of active combat with the mob.

I'm fairly confident that whatever it's PPM % is, it's relative only to a combat cycle. In about 8min of combat against Mag's last night, it procced 13 times. Compare that to my typical Primal Air farming cycle, where I get no less than 30 procs in a 5-7 min stretch.

This to me seems to imply that there is an internal cooldown of sorts, and that perhaps internal cooldowns themselves are relative to combat cycles, as I see the same effects from my Hourglass. It's quite a bit harder to test than with OoC, due to the short duration of the buff, but very frequently, if RotU is active when combat drops, and is still active when I re-enter combat with a new mob, I will see the hourglass proc again before it's technically supposed to.

I don't believe there is an internal cooldown. I had OOC proc instantly 2 times after each other several times (even once had a tripple proc in a 5 second window).

I'd say it's probably 2ppm base, but ppm works out a % value based on normal attack speed (so for cat it works it out as 2/60 = ~3%), but then it procs off instants too - obviously that means for cat it's more like 5% with all the instants you end up doing. For bear it works out as even more than that because of lacerate being instant and it working off a 2.5 attack speed. Almost certain it must work this way due to getting a lot less procs when just autoattacking in healing gear while doing 5 mans to get random procs just to help mana efficiency (and doing naxx trash pre-tbc). I'd agree with Athinira on the internal cooldown though, definitely doesn't have one as I've had it chain proc at least twice before.
