Looking for Stat Rating to % Values

[x1xruex1x]

Hello everyone, Rue here, I'm trying to find out if anyone can provide a table, layout, or anything that shows what the relative RATING to PERCENTAGE is for each stat.

From what I gather and see, the below is mostly accurate from path notes and what not.

Critical Strike: 400 rating is equal to 1% for the stat.
Haste: 375 rating is equal to 1% for the stat.
Mastery: 400 rating is equal to 1% for the stat.
Versatility: 475 / 900 for +1% to +Damage & +Healing / Damage Reduction

However, Arcane's Mastery is multi fold. There's +Mana, +Regen, & +Damage. From what I see, the 400 rating is +1% for Mana/Regen. However, I cannot find any details identifying what the value of rating needed is, in order to increase damage by +1%.

I keep hearing that it's more costly to get +1% damage with Mastery, than it is to get +1% damage via Versatility, and as such, Vers is more preferred. However, no one has provided the rating# to my knowledge, or that I've seen.

If anyone would be so kind as to provide the Mastery Rating needed to equal +1% Damage via Mastery, that would be phenomenal and greatly appreciated ^_^

I am not a numbers guy but I look at Lycoan's math, I saw this is his discord so I am quoting it out of context, hope it helps.

Definitely gives a starting point. I know there's got to be an exact rating# that'll give what +1.00% is equal to tho. I'm not a fan of mathing things out and figuring differences and what not

But yea, 400 to 0.71% is better than nothing so far. Thank you!


Anyone else got some info on it?

[x1xruex1x]

So, I'm not a huge math person, but if I'm right, it looks like about 563-564 Mastery Rating = +1% damage.

This is how I got to it, but again, I'm very hazy about the math:

400 = 0.71%
X = 1.00%

0.71 / 400 = 0.001775

0.001775 * 563 = 0.999325%
0.001775 * 564 = 1.0011%

So it looks like the 563-564 is the figure I'm looking for.

If anyone is better at math, if they could check this and let me know if I'm on point, or far off. This would be greatly appreciated.

Sorry, I just really want to get that mastery rating number that equates to +1% damage via mastery. Just really need the raw per point, not basing on the AC stack count. That's a different thought once I obtain this.

Edit: Just worked w/ a co-worker who's better at math than I, he said it should be about 563.38028 per +1.00% of mastery. So rounding, about 563.5 would be the sweet spot if all math is accurate.

Conversion Factors
400 mastery -> 1 Point -> 1%/Point
475 vers -> 1%
400 crit -> 1%
375 haste -> 1%

Arcane Charges are an extra (1.0+( 0.6 + 1/2Mastery%)) for damage. Every additional % is therefore 2xMastery, or 800rating.

Your math is wrong because you are ignoring the base 60% damage that Arcane Charges grant and not realizing the mastery damage value is additive to the base AC damage multiplier.

Conversion Factors
400 mastery -> 1 Point -> 1%/Point

I normally trust your knowledge base, Frosted, but I believe it is 333 1/3 mastery rating per 1% mastery for Arcane. I have 8503 Mastery and +25.51%. Deltoramasta has 9181 and +27.54%

That makes it 666 2/3 mastery per 1% bonus damage

We re-calc'd the mastery stuff after the nerf back in...Novemeber I want to say? I'll dig around in the discord logs when I get home to find the exact math behind it. But pulling from spelldata,it's implying there is a 1.2%/point conversion and 0.6%/point for the damage multiplier.

I guess I missed/forgot they changed the Point -> % conversion, whoops. Yeah, it's 400 rating / point, with a 1%/1.2point conversion ratio (instead of 1:1 like it was at some point).

so 400/1.2 -> 333.3 per %mastery, or 666.6rating per % dmg.

[x1xruex1x]

Ok, so then I need someone to explain to me this, since maybe I'm misunderstanding it overall.

Mastery: Savant
Requires level 78

Increases Mana Regen & Maximum Mana by 9.6%
Arcane Charges increase the damage of affected spells by an additional 4.80%

So with that, what I want to know, is what amount of mastery rating it takes to increase the second line of the "Mastery: Savant" skill from 4.80% to 5.80%.

The official data from Blizzard shows 400 rating = +1%. However, this doesn't take into account or work for the latter half of the Savant Mastery tooltip. I'm trying to solve for (X = +1% AC Dam) as the tooltip would reflect.


@Frosted:

Arcane Charges are an extra (1.0+( 0.6 + 1/2Mastery%)) for damage. Every additional % is therefore 2xMastery, or 800rating.

Your math is wrong because you are ignoring the base 60% damage that Arcane Charges grant and not realizing the mastery damage value is additive to the base AC damage multiplier.

I would like it if you might elaborate in more detail on this. I'm not sure if I had explained my request properly earlier, but just above I detailed what I'm looking for. Just the straight math it takes to get the tooltip to increase by +1% for the damage portion.

Given your math above, I'd like it if you could input your mastery rating into the equation where it would be fitting, and show how this equates out.

I'm not sure where your variables are as it'snot elaborated on above, so I don't know where I'm plugging in my mastery rating to see the outcome of the +AC Damage, whether it's supposed to show the tooltip +DAM or the +Dam per AC Charge.

I guess I missed/forgot they changed the Point -> % conversion, whoops. Yeah, it's 400 rating / point, with a 1%/1.2point conversion ratio (instead of 1:1 like it was at some point).

so 400/1.2 -> 333.3 per %mastery, or 666.6rating per % dmg.

So, in a straight forward answer, would this be accurate?

400 Rating = +1.00% Maximum Mana & Mana Regen
666.6 Rating = +1% AC Damage Increase

I'm really just trying to make sense of this as I'm seeing a bunch of data swinging around, but no allocation of variables so I can't associate what rating belongs to what +1 percentile for +AC Damage.

Sorry, I know this is all confusing, but I'm just looking for a cut and dry, then to have some backing data.

[Frosted]

mastery % = Rating/(400/1.2)

So 333rating / ( 400 / 1.2 ) = 0.99% Mastery. The 1.2 comes from the Points -> % conversion factor, which is different from every spec. Arcane Mana/Mana regen has a 1.2 conversion factor.

The damage portion of Arcane mastery has a 0.6 conversion factor. So Rating/(400/0.6) or 333/(400/0.6) = 0.4995%.

The AC damage bonus can just be simplified here to be 1.0 + (0.6 + 1/2*Mastery%), which is what I said originally. 1.0 is because AC is a damage increase multiplier. 0.6 is the base multiplier amount. 1/2Mastery% is how it scales with mastery.

So to get 1% AC damage, or go from 60 to 61% (or 1.6 to 1.61) you need 1.0 + ( 0.6 + 1/2*(1%Mastery), or 2%, or 666.6 rating.

[Kythos]

the +damage per charge on mastery rating is 1/2 the mana regen coefficient...

like Verse
( +5% damage done, then 2.5% damage reduced damage taken) for super eazy maths.

checked my armory...
around 28% mastery ---> ~8% additional damage per charge.

[x1xruex1x]

Thank you for the clarification. I just got home, so I'm gonna test the math against my rating number to see that I'm plugging it in properly.

[x1xruex1x]

Ok, so after checking. The 666.6 seems to be spot on for +1% towards the tooltip for damage.

However, I encountered an odd issue that I just can't fathom.

In the below, you can see that I have no gear on, 0 mastery rating. the gloves has +668 mastery, so ALMOST perfect match of the 666. So essentially it should equate to a +1%.

When I equip it, I noticed that my mastery rating in the tooltip went to 681...that's 13 points higher???
How the heck is this happening? The built-in mage armor passive is no longer in effect, so there's no more passive mastery. I don't have any food, flask, pot, anything on myself. Absolutely no gear, shirts, tabards, etc.

So yea, I'm now confused on this!


Aside of that, thank you for the rating# check.

[Ronark]

Since you are a Human, you get extra secondary stats- That explains the difference that you are seeing.

They still have that in the game?? I thought they got rid of that stuff way back when they tried to rebalance to racial perks?

Oh well. YAY FOR DATA BEING THROWN OFF...yet again, because of a human!


Thank you Ronark ^_^

It goes through a new iteration for what feels like expansion. Glad to help!

[Nemaro]

Hi guys, long time reader of the forums here but 1st time posting, this whole expansion I've had the kind of feeling that mastery is way undervalued, reading these calculations here are they based on 1 stack of arcane charge or 4? Because if 1% per charge is 666.6 rating then with 4 charges that would be 4%, making it way more efficient than vers. Again could be completely mistaken but I'm seeing better damage with mastery than vers.

No, 666.6 Mastery is actually exactly a 1% increase in damage done by these spells.

Arcane Blast Damage (before traits/vers) = 192.4% * [1+(.60 + M/2)*C], where C = Charges and M = Mastery

Assume M = 30% Mastery, Arcane Blast would do:

192.4 * [1 + (.60+.15)*C]. A 4-charge therefore does 192.4 * 4 = 769.6% spell power
If we add 2% Mastery (666.6 rating), the 4-charge Arcane Blast does

192.4*[1+(.76)*C = 192.4 * 4.04 = 777.3% spell power.

The increase in damage is equal to 7.7% of your spell power. However, that is meaningless when comparing to versatility, which is a raw % damage increase. We need to be looking at the relative increase in power. Therefore, we do a simple percent increase calculation: (new value - old value)/(old value).

(777.3 - 769.6)/769.6 = 1% increased damage

So 666.6 mastery rating equates to exactly 1% increased damage. Meanwhile, 475 versatility rating equates to exactly 1% increased damage. The reason you might see a dps increase with mastery is because of a reduction in Arcane Barrages required to maintain your rotation. In terms of raw output in which we ignore mana consumption, versatility is much more valuable.
