d) Can you tell if the initial Hemo that puts the DoT up gains the benefit of Sanguinary Veins, or does the buff not go up until after the Hemo has dealt its damage? This is probably best tested with a low-damage weapon and lots of AP. This would also be a good time to doublecheck the normalization status of Hemo.

Thanks, no I did not see any of that described buggy behavior. Guess it would have been helpful to have timestamps on.

a) I do not know what "true refresh" means but the DoT ticking timer is reset when you land a hemo strike.

To narrate a little of the below log
16 sec: The first hemo strike lands
16 sec: The 30% bleed debuff applies
17 sec: The glyph bleed is applied (seemingly always one second after the strike)
20 sec: bleed tick
23 sec: bleed tick
24 sec: The next hemo stirke
24 sec: The 30% bleed debuff is refreshed
25 sec: The glyph bleed is applied (not refreshed)
28 sec: 8 ticks of bleed happen 3 seconds apart with 1162 haste (9.07%)

We do not see a bleed tick at 26 seconds from the original or second hemo strike, the first bleed tick of the second strike happens at 28 seconds which is 5 seconds after the last tick of the original strike and 3 after the second hemo glyph is applied.

b) Again, the above was done with 1162 (9.07%) haste and we saw 8 ticks spaced 3 seconds apart, we see the exact same thing below with 0% haste.

c) Yes, if the original hemo strike is a crit, the hemo DoT can crit as well.

d) The initial hemo does not benefit from Sanguinary Veins if a bleed is not already present and hemo is still normalized (at least for 1-handers, I'd assume it's the same for daggers).

Here with I am attacking a lvl 60 dummy and expect approximately 12.56% reduction in damage from armor as observed earlier. I am specced into Sanguinary Veins and only hemo after the DoT is finished. I have 6501 AP and am using a 2.2 speed, 7.0 dps sword.

(2.2 * 7 + 6501 * 2.4 / 14) * 1.375 * (1 - 0.1256) = 1358.386 ~ 1360

Here I just spammed hemo with the hemo glyph up, we see the hits are approximately 1494 = 1358 * 1.10 (notice no hemo DoTs happen because hemo is being constantly refreshed)

A 2.6 speed white weapon: [Shortsword]. I can no longer reproduce those exact numbers now that the vitality buff is on the PTRs, but redoing the test with the same weapon (743 attack power naked) I get swings of 83/84 normally, 92/93 for the MH KS attack itself, and 99/100 damage for the melee swing during KS (on the heroic dummy). I assume that the difference in damage between the MH attack and the KS attack is normalization.

• Aldriana · 10/04/10, 12:12 AM

Your previous results were wholly consistent with normalization for a 2.6 speed weapon, and your new results appear to be as well. Hence, I'm going to mark KSp as normalized and call it good.

I did the following for blade flurry tonight:

Test 1. Naked except for a white level 1 throwing dagger, I spammed FoK for 60 seconds and in that time period got two full blade flurries in. 21 FoK, 56 energy remaining at the end, for a grand total of 791 energy. Subtracting off the 100 initial energy and the 12.5*30=375 energy that we know was regenerated while BF was down, we get 316 energy in 30 seconds or 10.5333 energy/second, almost exactly 2energy/second less than without BF. It appears if the 20% is additive with vitality. I repeated this test a couple of times and got very similar answers (within a couple of energy).

Test 2. Fully geared with 32.57% haste, same idea. End result of iteration 1 was 28 FoK and 32 energy and iteration 2 had 27 fok and 69 energy. Subtracting off the initial 100 energy and the 12.5*1.3257*30=497 energy we know regenerated while BF was inactive, we get 416.86 energy in 30 seconds or 13.895 energy per second. This is ~2.676 energy per second less than would be expected, almost exactly 2 * (1+haste%) energy per second.

rikilol · 10/05/10, 8:58 PM

A quick comment on Haste vs. Energy Regen:

There is an existing API function call GetPowerRegen() that returns the current regeneration rate per second. However, this function seems to be bugged on the PTR since it doesn't include the effect of haste. It shows 10 without Vitality and 12.5 with Vitality. Though I haven't had a chance to test the regen rate for Combat spec yet, it feels like the game is treating 10 or 12.5 depending on the talent, as the base regeneration rate. So the haste effect should be multiplicative with Vitality. I will try to confirm this.

I am not familiar with the oddities Backstab and Ambush have with Opportunity but it appears that Opportunity applies to the whole damage calculation for Backstab and Ambush. Sorry if I've missed the point and this is all known.

For this test, I only had points in RS so that I would have consistent AP of 6501 for all of the tests and Sinister Calling for both Backstab tests and Master of Subtlety for both Ambush tests. I also did the test on a lvl 60 dummy expecting 12.56% DR from armor as previously observed. I am also using a 1.6 speed 11.1 DPS white-quality dagger.

((1.6 * 11.1 + 1.7 * 6501 / 14) * 2 + 345 * 2) * 1.25 * (1 - 0.1256) = 2518.56 ~ 2520

Same thing with Opportunity we see the expected flat 30% increase in damage

1.30 * 3274.13 ~ 3280

Doing the same thing with Ambush, I see the same pattern except all of my actual numbers are slightly off my expected

((1.6 * 11.1 + 1.7 * 6501 / 14) * 2.7493 + 367 * 2.75) * 1.10 * (1 - 0.1256) = 3105.12
Off by about 18.88 of the observed 3124

Same deal with Opportunity

1.30 * 3105.12 = 4036.64
Off by about 27.36 of the observed 4064

I went back and tested Ambush with no talents and the same dagger (5253 AP)

((1.6 * 11.1 + 1.7 * 5253 / 14) * 2.7493 + 367 * 2.75) * (1 - 0.1256) = 2458.53
Off by about 15.47 of the observed 2474

Maybe the Ambush calculation was changed and I just didn't know or is this the oddity you were referring too?

Lightshadow · 10/06/10, 12:28 PM

16. In early beta we saw some odd behavior with Rupture scaling under Revealing Strike. Has this been fixed to always give the full 20% damage bonus?

I did a bunch of testing around this a couple days ago and it's definitely still bugged the same way it was before. All tests done naked with a 2.6 speed white sword and 714 AP. First column is the observed tick, second column is the predicted tick with a full 20% bonus, third column is the predicted tick if only the AP were being buffed, fourth column is the predicted tick if only the base damage were being boosted, and the last column is the predicted value if, no matter how many combo points you used, the damage boost was equal to just boosting the base damage of 1cp. (A flat 28.96 damage boost per tick). Only the last column has reasonable predictive power and even then it's not exactly spot on. (+/- 1.5 dmg/tick).

Side Note: I haven't managed to get a glyph of revealing strikes on the PTR to test this with the 30% buff, but I can confirm there's absolutely no change in the damage/tick from the glyph of rupture. I'll update this post when I find a RS glyph.

CP	Observed   Full Bonus	Only AP	   Only Base	Flat Dmg Boost
5	274.38	   292.50	249.13	   287.18	272.71
4	254.00	   268.11	228.38	   263.28	252.39
3	232.22	   243.00	206.70	   238.62	231.46
2	209.00	   216.24	183.56	   212.74	209.16
1	183.17	   186.90	157.85	   184.71	184.71

Edit: Got a glyph of Revealing Strikes. Still bugged. What was effectively a 12.6% bonus before is now a 19% bonus (50% higher) and so on down the CPs. I've presented that "30% of 1 CP's base damage" column again because it's the closest match I can get, but it's still +/- 2damage/tick, which would be unusual for a fixed damage ability.

	Actual	   Full 30%	30% of 1cp Base DMG
5	290.00	   316.88	     287.19
4	269.00	   290.46	     266.87
3	246.83	   263.25	     245.94
2	223.40	   234.26	     223.64
1	197.00	   202.48	     199.19

• Aldriana · 10/06/10, 1:26 PM

Did you check how much damage it does without RvS, or are you basing that off the damage formulas? If it's the former, could you post the numbers you came up with? Perhaps I'm missing something, but your numbers don't seem wholly consistent with the wowhead damage formula for Rupture - a 5 CP Rupture at 714 AP should be doing ((141 + 20 * 1 * 5 + 0.0375 * AP * 1) = 241+.0375*AP = 267.8 damage base, shouldn't it? Which is more than some of the "buffed" numbers you've proposed? Or is the wowhead formula wrong?

Lightshadow · 10/06/10, 1:35 PM

Sorry, all the testing was at level 80 on the current PTR build, not at 85 in the beta, so the default formula for rupture listed on wowhead isn't right (you have to move the slider down a bit to level 80). I did check to see that the tooltip matched the predicted wowhead values which matched the observed values on the PTR.

Edit: The formulas on wowhead simplify a bit to

1	580 + 0.06 * AP
2	815+ 0.12 * AP
3	1086+ 0.18 * AP
4	1393 + 0.24 * AP
5	1736+ 0.3 * AP

And the baseline results were:

	Predicted	Actual
5	243.75		243.5
4	223.43		223.5
3	202.50		202
2	180.20		180.5
1	155.75		155.75

Edit: I can confirm that this bug is still present in the 10/6 PTR build.

**EDIT**

Added Log(s):

One handed - 1.4speed dagger - 1 hour - No Poisons

3168 Melee/poison hit/crit/tick
66 Applications of Hurricane Buff

2.1% Proc

Ran the log till my dagger broke. If I'm correct in my math it looks to have about a 2% proc off melee hit. No ICD since it refreshed itself a number of times.

Running another log now dual-wielding with DP/IP.

Dual-Wielding - 1.4/1.8 - DP/IP - 94 Minutes

12217 melee/poisons hits/crits/ticks
232 applications of Hurricane Buff

1.9% Proc chance.

Does it stack? Can It be refreshed?

Yes, it does stack. And it can refresh itself multiple times.

Taken from the one handed log:

[20:30:34.634] Darkmisfit gains Hurricane from Darkmisfit
[20:30:36.236] Darkmisfit's Hurricane is refreshed by Darkmisfit
[20:30:41.274] Darkmisfit's Hurricane is refreshed by Darkmisfit
[20:30:53.135] Darkmisfit's Hurricane fades

[20:44:15.358] Darkmisfit gains Hurricane from Darkmisfit
[20:44:18.255] Darkmisfit's Hurricane is refreshed by Darkmisfit
[20:44:25.838] Darkmisfit's Hurricane is refreshed by Darkmisfit
[20:44:37.699] Darkmisfit's Hurricane fades

Can Poisons proc it?

Based on the logs (unless I am absolutely oblivious..which is possible) I would say Yes, poisons can produce a proc.

[21:14:41.336] Darkmisfit hits Old Worlder's Training Dummy 1 (O: 1298)
[21:14:41.796] Darkmisfit Instant Poison Old Worlder's Training Dummy 1 (O: 1533)

Did anyone check to see if the Hemo glyph procs HAT when it crits?

Rupture crits on live do.

#36 - Partial resists.

It's my understanding Partial Resists have been removed in Cataclysm. From personal experience and testing on live (i.e. 3.x.x) around 45% of all spelldamage had partial resists. Looking through all the screenshots in this thread I do not see a single poison affected by a partial resist.

From the Cata Frost DK thread:

That's an interesting find, if this change was intended; I wonder if we may see a change to glancing blows in the future?

Torael_7 · 10/09/10, 12:31 AM

I read through the thread and didn't see this asked, so here's something else to test.

Do poisons get the benefit of crit from Agility now, or are they still considered spells in that particular regard?

Now, when Blizzard implemented Find Weakness on PTR, it's time to do some tests.
Tests done with premade on PTR, no proc trinkets/enchants and no meta gem.

1. Gouge on clean Heroic Training Dummy (lvl 83)

Damage: 588
With tooltip damage of 993:

damage reduction:
dr = (993-588)/993 = 0.4078
Armor: 
a = dr*C/(1-dr) = 0.4078*15232.5/(1-0.4078) = 10492

2. Gouge on the same dummy with Find Weakness applied:

Damage: 738

damage reduction:
dr = (993-738)/993 = 0.2568

Armor: 
a = dr*C/(1-dr) = 0.2568*15232.5/(1-0.2568) = 5263 ~ 5246 = 10492/2

So far so good, 50% armor reduction as promised.

3. Now let's test interaction with Expose Armor, which gives 12% armor reduction.

Damage: 762

damage reduction:
dr = (993-762)/993 = 0.2326

Armor: 
a = dr*C/(1-dr) = 0.2326*15232.5/(1-0.2326) = 4617

Multiplicative stacking of EA and FW predicts armor to be

a = 10492*(1-0.5)*(1-0.12) = 4616.38 ~ 4617 from the prev. test

Additive stacking would give 3987, which is far from the test results.

TL;DR: FW provides 50% multiplicative armor reduction.
