Acumen’s proc on a Kara run

Well, I posted that I am getting the Shattered Sun of Acumen neckpiece, which I did on Wednesday. I swapped Ritssyn’s Lost Pendant, hence losing 14 spell damage on equip. What I have been curious about is how often the Light’s Wraith actually proc during a run. Is it better to swap Ritssyn back for some fight?

With the help of WWS report, here’s my proc during our last Kara’s run:

1. Attumen – 150 sec – 0 proc.
2. Moroes – 192 sec – 3 proc.
3. Maiden – 91 sec – 1 proc.
4. R&J – 188 sec – 3 proc.
5. Nightbane – 424 sec – 3 proc.
6. Curator – 161 sec – 1 proc.
7. Illhoof – 267 sec – 3 proc.
8. Shade – 211 sec – 1 proc.
9. Netherspite – 276 sec – 2 proc.
10. Prince – 221 sec – 1 proc.

So, that’s a proc every about 121 sec. The nightbane’s fight may skew it the number. And I’m assuming that I’m constantly casting offensive spell (my priority is VT, SW:P, MB, MF, and when appropriate, VE (usually after VT), and SW:D (usually after MB)). I’m really surprised that there’s no proc during Attumen and a very low proc times on Curator. Those were the most constant fights (where I don’t have to move) that I did.

Another number that I have is 15 procs for 32 minute dps time during last Sunday’s Gruul. And 42 procs fir 81 min dps time for overall Kara (including trash). So, the proc rate varies quite greatly, from once every 90 sec to once every 2 min. Don’t you think the proc rate is a bit low? Is it better to have the constant steady damage that Ritssyn bestows, especially with my spell rotation?

  1. If your proc rates are indicative (about once every two minutes) I’d say you were probably right to upgrade – at that frequency it adds an equivalent of about +18 spell damage over time. The problem is that the true benefit of the pendant is dependent on when it procs. To get the most out of it, you need to cast your two dots while the buff is active – vampiric touch and shadow word: pain carry the highest spell coefficients (100% and 110% respectively). If it procs out of rotation, or you happen to be moving and unable to cast, or it procs at the end of some trash and the buff is wasted, it clearly falls in comparitive value to Ritssyn by a long way – although I don’t have the math skills to work out if it remains a better item. If you have the time to do some tests on Dr Boom I’d love to see the results.

  2. Merlot, care to explain the calculation to get +18 spell damage from proc? I’m really interested in understanding that.

    Wasted buff is exactly what I’m worried of although I am usually pretty good at keeping VT and SW:P up at all time. Hence, I’m a bit disappointed with the low proc number during Attumen and Curator.

    I’ll give the ol’ Dr. Boom test a try for sure :)

  3. Hmm. My reasoning was this: 20 spell damage for 10 seconds is the same as 10 damage for 20 seconds. That’s how I arrived at 18 as an equivalent for the acumen proc (based on 120 damage for ten seconds every two minutes). That could well be a monumentally idiotic assumption to make (I’ve been know to make bigger gaffs…) Now that you’ve challenged me on it, I feel on very thin ice lol!

  4. With that assumption (and no…it wasn’t idiotic :) ), shouldn’t that be +10 damage instead (10/120*120)? With proccing every 1.5 min gives an additional +13 damage? If this is correct, it seems that I should be swapping Ritssyn back.

  5. Urgh, I clearly should avoid all math-based discussions!

  6. And what would be the fun of that? :)
