Q u o t e:
Gain for Fireball from Spell Impact + Playing with Fire + Firepower

Tooltip Min: 898
Tooltip Max: 1143
Plus Damage: 1508

Datapoints: 1526
Min Observed: 2875
Max Observed: 3166
Expected Spread 1: (1143 - 898) * (1.06 * 1.1 * 1.03) = 294.2401
Expected Spread 2: (1143 - 898) * (0.06 + 1.1 * 1.03) = 292.285
Expected Spread 3: (1143 - 898) * ((0.06 + 1.1) * 1.03) = 292.726
Expected Spread 4: (1143 - 898) * ((0.06 + 1.03) * 1.1) = 293.755
Observed Spread: 3166 - 2875 = 291

Gain Formula: Observed Value / Expected Value without Spell Impact
Expected Min: (898 + (3.5 / 3.5) * 1508) = 2406
Expected Max: (1143 + (3.5 / 3.5) * 1508) = 2651
Gain by Min: 2875 / 2406 = 1.1949293433084
Gain by Max: 3166 / 2651 = 1.19426631459826

Proposed Gain Formula 1: (1.06 * 1.03 * 1.1) = 1.20098
Delta by Min: abs(1.20098 - 1.1949293433084) = (0.00605065669160454)
Delta by Max: abs(1.20098 - 1.19426631459826) = (0.00671368540173534)

Proposed Gain Formula 2: (0.06 + 1.03 * 1.1) = 1.193
Delta by Min: abs(1.193 - 1.1949293433084) = (0.00192934330839534)
Delta by Max: abs(1.193 - 1.19426631459826) = (0.00126631459826454)

Proposed Gain Formula 3: ((0.06 + 1.1) * 1.03) = 1.1948
Delta by Min: abs(1.1948 - 1.1949293433084) = (0.000129343308395535)
Delta by Max: abs(1.1948 - 1.19426631459826) = (0.000533685401735262)

Proposed Gain Formula 4: ((0.06 + 1.03) * 1.1) = 1.199
Delta by Min: abs(1.199 - 1.1949293433084) = (0.00407065669160467)
Delta by Max: abs(1.199 - 1.19426631459826) = (0.00473368540173547)

---

Conclusion: Formula 3 seems the most likely. So atleast for modeling effects with Firepower, PWF, and Spell Impact, Spell Impact should be added to Firepower, and then PWF multiplied in.

Q u o t e:
Gain for Fireball from Spell Impact + Playing with Fire + Firepower + Arcane Instability

Tooltip Min: 898

Delta by Max: abs(1.230644 - 1.23010184835911) = (0.000542151640890332)

Conclusion: Arcane Instability can be applied after the summing of Firepower and Spell Impact.

Side note, when I finally have some time away from work (I think that will happen...uh... sometime...) I'll be reconfirming all this stuff live side, and doing more user-friendly writeups of it all.

1 peepee + 1 vajayjay, add in 1 !**!#ie and 1 egg = 50% chance boy, 50% girl. There ya go.

Haha, s.permie was edited.

Srry to invade your research.. =) but im beguining to look into these thing of theorycraft and have a question that I think you will know the answer.. =).

Whats the crit coefficient for the mage's spells? are they fixed? all have the same coefficient? or do they change like the spell power coefficient?

Thank You!

No interruption at all. Crit has no 'coefficient', it has a rating to percent conversion though which is constant across all spells and classes. Info on that can be found at http://www.wowwiki.com/Combat_rating_system

Thank you very much for your answer! I looked all over wowwikki and didnt find it.. =).

since im here.. let me ask you another thing.. have you tested the cap of hit rating? is it true that the cap does not exist anymore? now we can have 100% hit?

thx!

I personally have not tested it, but I know it was tested repeatedly. I can say anecdotally that I've only seen one resist since I've been in Northrend, and it was a target three levels higher than me. I'm walking around with ~7% +hit from gear on me, so I'd expect no resists until three levels up.

Documented test to follow when I get 80 and hit capped gear against a 83 raid boss. That dummy is going to take a very long term beating.

Hello again,

Another question, I have recently passed by some dps calculating sites for mages. That take in consideration the new specs and all. And when comparing spell dmg vs hit rating I noticed that puting 386 hit rating or putting 386 spell dmg. The spell dmg one comes out winning, are these forums correct? 1 spell power point is worth more than 1 point of hit rating?

Thx again!

It all depends on your relative levels of other stats and what talents you have. If you give yourself 17% hit from gear and have 3% hit from EP, you're wasting 3% hits worth of itemization that could be spent elsewhere.

Check out the TCoM ( http://zaldinar.bounceme.net/tcom/ ) and see how things work.

Yes, I understand.. but thinking on the following situation (I used the website you pointed out):


- I have elemental precision
- I have 1200 spell power
- I have 12% hit

If I increase 1 spell power point, it generates more dps than 1 hit point. And I always learned from all mages that hit rating is always more important than spell dmg.

Is this correct? Has blizz really changed the priority of hit rating?

In LK the values have shifted, the 'value' of hit is not only in its average DPS contribution, but its removal of the opportunity to underperform. The higher your spell power the more the hit will be worth, the lower your hit the more it will be worth. I'm designing a grid plot graph util for the TCoM to show this, but it isn't ready for use yet.

Back to the top because I found this very useful.

Living Bomb Glyph
Patch: 3.1 PTR build 9684
Target: Target Dummies in Theramore

Level: 80

Method: Living Bomb with assorted talent / CSD configurations, isolate crit and noncrit values using the glyph.

Effects			Non-Crit		Crit		Gain

None			607			910		1.4992

CSD			627			969		1.5454

CSD + 5 Burnout		627			969		1.5454

5 Burnout		607			910		1.4992

Casting Combustion and then Living Bomb did not use any charges. Charging combustion to 7 stacks with a base 27% crit rate resulted in 7 / 20 ticks critting. No Living Bomb ticks generated ignite debuffs. The glyph does not appear to interact with any crit gain effects other than CSD.


EDIT: Later builds of the 3.1 PTR have changed this behavior. This test will be repeated following the conclusion of the PTR.




Ice Lance Glyph
Patch: 3.1 PTR build 9684
Target: Target Dummies in Darnassus

Level: 80

Method: Ice lance the target, then frost nova and ice lance them again, record on different target levels to see approximate gain.

Target Level		Pre Nova		Post Nova    		Gain

60			252			763			3.0277

80			236			712			3.0169

83 (boss)		226			927			4.1017

Conclusion: Ice Lance on targets of greater level than you does indeed provide quad damage when glyphed.

Living Bomb DoT
Patch: 3.2 Live
Target: Wolf in Dun Morogh
Level: 80

On live with 2070 spell power specced for Playing with Fire and Firepower got a tick for 860.

((1380 / 4) + (2070 * 0.2)) * 1.03 * 1.1 = 859.947

the LB DoT is now properly benefiting from Fire Power.

Have you done any testing to see if talented less chance to hit spells (Heightened Senses and the like) can be mitigated by +hit? Pookz was talking about it on WoM and I wasn't sure, so I'd figure this would be one of the better places to ask :)
