Here is some test data for BIS Ret Paladin DPS with and without a cancel aura addon to remove Chaos Bane as soon as it procs. Bottom line, it is a 2% to 3% DPS net gain to cancel Chaos Bane immediately and start collecting fragments all over again. This is due to 2 reasons:
- How quickly we accumulate fragments as Ret Paladins. I averaged 1.5 fragments/second in my test and this is without any raid buffs. That results in a Chaos Bane proc every 6.7 seconds for approximately 2750 damage. This means that our average strength buff over the course of the fight doesn't take a huge hit when we cancel Chaos Bane and start over. You can see this in the tables below; without cancelling Chaos Bane my average strength buff was 222 and when cancelled my average strength buff was 148.
Looking at retail DPS logs, I see 1.9 fragments/second but that paladin was raid buffed. It is still incredibly fast for us.
- While under the effect of Chaos Bane we cannot collect any fragments. So while the strength buff is held constant at 270 for 10 seconds we would have missed out on at least one more shadow explosion during those 10 seconds.
I came up with the numbers above using two methods; One was with testing on a HC dummy in IF for 2.5 minutes using Recount. The other method tries to explain that DPS gain using math. The two numbers are very comparable; cancelling Chaos Bane is a 2% to 3% DPS gain or approximately a 180 DPS gain.
DPS Variance Estimate – Test Data
- Target: Heroic Dummy in IF
- Duration: 151 seconds using SoV (open with Wings and pop wings again when off cooldown)
- FCFS Priority: Judgement, Divine Storm, Crusader Strike, Consecration
- Number of Shadow Bane Procs: 22 when cancelled and 9 when Shadow Bane was kept for 10 seconds
- DPS Variance: Testing shows cancelling the buff to be a 224 DPS increase or 3%
You may wonder looking at the above chart why melee DPS was not obviously higher when Chaos Bane was kept since average strength buff was higher. The answer is, it actually is higher but RNG on such a small sample size can be very deceiving. I had about 50 melee swings on every test; the average melee hit when I kept the buff was 2900 but it was only 2810 when I cancelled it. As expected it is a modest gain and all it takes is a few extra lucky crits to overshadow the difference. The main thing I wanted to show with the chart is the big jump in Chaos Bane shadow damage. That part is a lot more reliable.
And for the reason above, I would say the DPS gain is closer to 2% as per the math below.
DPS Variance Estimate - Calculated
- Assumed 1.5 fragments/second which was confirmed by testing
- When Shadow Bane was kept for 10 seconds the average strength gain throughout the fight was 222
- When Shadow Bane was cancelled using FreeMe the average strength gain was 148
- The table below shows how I came up with these averages
- DPS Variance: Calculation shows cancelling the buff to be a 141 DPS increase or 2.1%
Math Example:
At the end of the first 2 seconds I expect to have 3 fragments. That translates to average of 60 strength for the first 2 seconds; 30 strength at the end of second #1 and 90 strength at the end of second #2.
At second #7 I expect to have 10 fragments at which point I could keep a 270 strength buff for 10 seconds or cancel right away and start over.
If I keep the buff then my strength gain for the next 10 seconds is 270 of course. If I cancel as soon as I get the explosion then I am assuming that my average strength the second of the explosion is 135; 270 for the first 0.5 seconds and then 0 for the last 0.5 seconds then I start back up with 30 strength in the next second and so on.
Per RAWR and the 3.3 Ret Paladin DPS Spreadsheet an increase of 1 in strength results in a DPS increase of about 1.5 which sounds reasonable, that works out to 1% Strength gain to 0.65% DPS gain which also makes sense.
So the extra 74 in average strength I gain by keeping the buff yields an extra 111 DPS but when Chaos Bane is cancelled I can get an extra 5 explosions/minute which would be closer to a 230 DPS gain.
The net gain favors cancelling the buff and testing data supports that theory. Faster fragment generation during raids would make the DPS gain even more significant when cancelling the buff.

My favorite way of cancelling Chaos Bane is using a lightweight addon called Freeme. Once you install it you type /Freeme 73422 and it will cancel Chaos Bane immediately. It can be easily turned off with the command /Freeme off.
