I think LockApologist was asking if Rune Strike triggered the extra damage from Necrosis or the procs of BCB and Killing Machine.

Sorry, I guess I wasn't clear. I understand that my dodge/parry triggers rune strike. I understand that Necro/BCB/KM are triggered from my auto attacks hitting.

My question is, since Runestrike is an on next melee attack, will it proc the 'on auto attack' talents listed above? So, if I use Rune strike, will it also apply BCB/Necro/KM? i.e. Heroic strike proc'ing old Wind fury vs MS not proc'ing old Wind fury

It might as well be 100% there's rarely a fight i'm in where it doesn't proc and using the Blood Strike glyph that causes blood strike to do +20% damage to snared targets is a nice increase to dps.

Most frost builds I've seen all seem to take all 5 points in Killing machine. I even took it in a build I just put together. But, I find myself wondering if it's really worth the 5 points if your using a 2h wep. I'm 72 at the moment, so still leveling. It doesn't seem like I'm doing many auto attacks. I'm using PS>IT>BS>BS>OB>FS. After that most mobs are dead. Bottom line, is it really worth 5 points if you're using a slow 2 hander?

The Desecration snare does not, to the best of my knowledge, work on bosses, making the BS glyph useful for trash and PVP only.

Short & vague answer: It depends on your critrate, hitrate, spell pen, and what you use the proc on (need a spreadsheet to figure it out).

Longer, mildly promising answer:
(Warnings: Napkin math, no resist or miss taken into account)

IF...
... You have a 3.5 speed weapon
... Your critrate is 10%
... You succeed at using KM on Frost Strike ONLY
... Frost Strike is critting @ 260% (how off is my memory? :-/)

You will see up to a 41.4% increase in Frost Strike damage.

A 20% critrate yields a 32% increase and a 30% critrate nets a little above 25%.

Remember, the key is that you'll only be using an applicable ability so often so while you only crit, say, one in 10 swings, you just bumped another ability's critrate enormously because you use it about 1/3rd as often!

Edit: Ok, so Frost Strike Crits for 245%--that probably lowers the increase a bit but not a horrible amount. Probably 5-7.5% per.

Death Coil's tooltip does not indicate the coefficient calculation, and thus will only show the base damage.

the tooltip of DRW says that it will perform the same attacks as the death knight.
It follows that if you do a death strike, the DRW will also do a death strike.

My question is, however, does the DRW's death strike heal you?
i'll try to test this later myself, if no one has an immediate answer. i'm also interested in knowing if diseases applied by the DRW stack with yours, if it can proc bloodworms, etc.

No, you can't be healed by its DS, nor should it be able to proc bloodworms. HOWEVER, if you use Raise Dead while Dancing Rune Weapon is active, it will summon a second ghoul that will last for the remainder the DRW's duration. I haven't levelled high enough to test it, or asked a level 80 player to, but I suspect the same sort of thing can happen with Army of the Dead.

Since I don't have any spell damage, what is the coefficient?

As mentioned in the DK DPS Compendium, Death Coil has a 15% AP coefficient.

As with anything tank based, your initial concern should be to become uncrittable through Defence, this will also increase your dodge/parry more than looking at individual ratings. There is some theorycraft for DK tanking around, a lot is on DeathKnight.info but also check out TankSpot

I find it useful to utilise the Death Rune's ability to be used in place of another rune. Mostly when AE tanking (as frost), I can do D&D, HB, Pestilence, PS, IT, Blood Tap, BB as it brings up death runes, allowing Bloodboil to be used. But, then again, I do tank for maniacs sometimes. As D&D + HB should be enough to hold most things.

Question about the Blood Strike Glyph.

Blood Strike

1. Does it work on raid bosses if say, frost bolt debuff, or whatever other snare is up? I ask since most bosses aren't affected by snares and was wondering if this would work.

2. Does it work with heart strike? Since heart and blood strike are interchange-able in many places I'm not certain.

As far as #1, I can't think of any snare debuffs that bosses are affected by.

#2, yes, it definitely works for Heart Strike.

The glyph is good for Unholy mainly, with frost as a slight second. Descration will mean anything you're dpsing that isn't snare immune is snared for 60% of the time (and all the time that you are bloodstriking). With frost, depending on whether you take the appropriate talents to apply a snare to Frost Fever, it's useful.

this might be akin to mage's Torment The Weak, which only works off of slow.

Does Shadow of Death result in a threat wipe? I assume the answer is yes but I was wondering if anyone has tested this.

You're asking if 4% haste is worth 1 talent point. That depends on the portion of your overall DPS done by autoattacks and (when tanking or solo) rune strike. If that number improves by 4%, is it greater than 1% of your overall DPS? If so, it's a good talent. Once you're invested in icy talons, it seems like imp. icy talons is an obvious choice for raid buffs.

So Haste is with a frost spec not that useless.

Haste isn't useless for any DK spec. It's just not as valuable per point of item budget as other stats, like strength, hit (until cap), crit, etc. 20% is a ton of haste.

Yes. Died while tanking, boss immediately proceeded to run around gibbing everyone else as I chased him around in ghoul form helping finish him off.

No rune strike does not proc BCB/Necro/KM.

Figured it out myself... and chad beat me to it too
