Your heart strike example isn't conclusive of anything. You can't arbitrarily choose one critical strike out of a string of hits and use it for calculations. If you choose his lowest heart strike, 2632:

7514 / 2632 = 2.854

For critical damage bonus math, I was going off a previous post in the thread:



2. Chaotic Skyflare Diamond adds 3% crit damage, not 30%.
Now am unsure how how much that makes the modifier, because in TBC this same bonus used to add 9% damage for casters, but I'm not sure if death knights spells follow the trend. Assuming it does:

Using the following calculation:
Normal spell crits for 150%. Runic Focus doubles the bonus.

150% * 1.03 = 154.5%
154.5% - 100% = 54.5% (this is the crit BONUS damage)
54.5% * 2 = 109% (runic focus doubles the bonus damage)
100% + 109% = 209% (total damage on a crit)

So if the meta works this way for us as well it should add 9% damage on a crit. If it doesn't then most likely it adds 6% (200% * 1.03 = 206%).



I based my math on the assumption that GoG, RoR, and VS work like the meta does. The math on the meta working that way was conclusively stated in mage, warlock, and other forums during TBC.

For Heart Strike: I was simply trying to point out that the crit modifiers didn't work that way even though it wasn't conclusive it's a point made isn't it?


My understanding was also that the crit bonus formula worked as: (1*1.X (Multiplier))+ 100% and it would give us the bonus damage.

I had never seen this CSD math. Figuring a crit mod aura of 45% with the following math we would have:

245%*1.03 = 252.35%

and using "another" formula

200%*1.03 = 206%
45% *1.03 = 46.35%
46.35% + 206% = 252.35%

So it might actually add 7.35% with MoM and GoG?

But HB doesn't yield the same results:

150% * 1.03 = 154.5%
154.5% - 100% = 54.5
54.5% * 2.25 = 122.62%
100% + 122.62 = 222.62% total damage

or would it work:

150% * 1.03 = 154.5%
154.5% - 100% = 54.5
54.5% * 2 = 109%
45% * 1.03 = 46.35
100% + 109 + 46.35 = 255.35% total damage

So does an HB have a bigger or smaller bonus damage due to crits?

I'm not really sure if the math applies to the other crit bonus damage multipliers as well.
The weird way of calculating was perhaps unique to the meta gem.

It was the same way back in TBC with the Chaotic Skyfire Diamond, and applied to casters who had a "100% more bonus damage"-talent, like warlocks with Ruin and Shamans with Elemental Fury.

That is why in my original post I stated that i did not know how this applies to DK spells with Runic Focus.

The problem lies in the wording. The meta gem clearly states:

"Critical damage increased by 3%"
Critical damage (without modifiers) is 200%.

Guile of Gorefiend however states:
"Increases the critical strike damage bonus <...> by 45%"
Critical strike damage bonus (without modifiers) is 100%
(its the bonus you get from critting, which is 100% on top of the normal 100% damage)

One could assume that runic focus does not modify the meta in the way that caster talents do, so the base crit bonus for both spells and melee.
This assumption is risky because i have no idea how blizzard modeled it.
Did they say: Ok the bonus damage of spells for DK just get doubled much like how casters get talents for it.
Or did they say: Ok we just get the 200% crit modifier as a base, so its unaffected by talents or the meta gem.

I have no idea, so i guess we'd have to account for both.

Therefor it changes calculations a lot. If i extend this thought of mind in this way, the calculation should be like this:

----------

Assuming 200% crit modifier is a base given, we first apply the meta gem and then apply GoG

200% (total crit damage) * 1.03 (meta) = 206% damage
106% (bonus crit damage) * 1.45 (GoG) = 153.7%

Putting things back together:
100% (base dmg) + 153.7% (bonus dmg) = 253.7%

----------

Assuming 150% crit modifier is the base, and runic focus is just a passive ability that multiplies the bonus by 2, we get a slightly different result:

150% * 1.03 = 154.5% damage
54.5% * 1.45 (GoG) * 2 (Runic Focus) = 158.05%

Putting things back together:
100% + 158.05 = 258.05%

It's kind of hard to tell since due to the way they differentiate wording on the meta and talents, as well as not knowing of the meta gem is applied first or after the other calculations (which of course provides different results).
