Ok, so does it replace ImpTClap or CoT on the target?

It's damage does seem to be affected/buffed by some spells from what I've read here. As it's frost damage, I think this enchant could be focused more towards Death Knights if their talents can boost the proc damage, and they do both spell and mellee damage?

Also are their not some debuffs DK's can do which increase the amount of frost damage taken by the target? This could again increase the damage from this?

Definitely the slow effects will be useful if DK's don't have a thunderclap type ability. Will definitely make a nice cheap levelling enchant as mentioned, and could be useful in arena's...

Hello all. First time posting here, hope I can help out with this, if in any way possible.

I play an enh shaman, and I put the Deathfrost on my offhand, went to Blasted Lands and started going at it on servants. All I was able to use was my combat log with timestamps (forgive me, few mods as possible.) My main goal was to see how many PPM i could get, first I tried with a combo of shocks, reflective buffs/shields, and melee attacks. 5 procs was my best, so i came back and tried a test using only melee attacks. During the last minute of the test, which lasted about 5 or 6 minutes, I recorded 7 procs of Deathfrost. The time between the first and last procs was 32 seconds.

Now, I'm a little confused by this, although I haven't read anywhere of a definitive PPM, the rumor mill was suggesting 3 PPM. The proc previous to that string was 45 seconds ahead of it, and if I count all procs 1 minute from that one, I get 4 which is a little closer.

I have yet to test it with a dual wielding DF setup, but it would be nice to see the PPMs increase wouldn't it? I hope this has been helpful info.

I would assume it does, however if a boss is immune to something like "Curse of Tongues", he'll probably be immune to the deathfrost effect as well. The effect is marked as physical however, so it should (in theory) persist trough the shields at the illidari council and may have a use there for the rogue helping with interrupts.

Another thing, worth investigating, is whether is procs on direct damage (spells) only, or also aoe such as arcane explosion / consecration. And, if the enchant has two components like Sapphidia stated, whether it can proc off a rogue's instant poison. (unlikely though as blizzard fixed double triggers)

Other than on trash however, i fail to see the utility of the enchant other than for pvp. Both thunderclap, mind numbing poison and curse of tongues are clearly superior as individual debuffs in pve raids and with an 8 second duration it's also fairly short compared to the other debuffs.

Yes, that's right. My Deathfrost was proccing last night for 165 last night, so some multipliers are definitely in effect.

That being said, I'm not quite sure which ones were, I'm in a standard tanking build, so my only Frost-affecting multipliers would be One-Hand Weapon Specialization for +5% to all damage, but that only increases a 150 proc to 157.5

Had some trys last night on a friend:
550 mele hits
2,8 MH 1,5 OH both enchanted with deathfrost. ( hit & expertise caped )
39 Procs
proced while active ( 3 times in a row )

If 1H Weapon Spec does affect Deathfrost, it was probably a combination of it and Misery.

If it doesn't, it was most likely Curse of Elements.

From what I saw during tests on blasted mobs:

-It can refresh itself
-Apparently has diminishing returns (when the proc refreshed the debuff, the 2nd debuff applied faded way faster than the initial 15s)
-Doesn't proc off consecration (not even with the 1st tic)
-Procs off Judgements, but with a very, very low procrate (like for melee hits, not the 50% I hear about from casters)

This enchant sounded good for us rets, at least in pvp, but the (oh so strange) way our combat mechanics works won't allow it to be half as useful as it should be.
Still sounds nice for shamys tough.

If somebody can come up with a way to test if it can proc from SoB / SoC or SoR and wich get the spell or melee procrate, please let me know... I can't think of a way to see if the white hit or the seal triggered the proc atm.

A lot of information here.
I have a 70 frost mage.

Will this stack with any talents?

Seems like if it did for a frost mage this enchant would be awesome.

Some quick testing:
It doesn't proc off Molten Armour.
With AM spam, I got procs at 25s and 26s and more. So, cooldown seems to be 25s.
It procs off AoE effects.

Someone reported that it doesn't proc off DoTs. I tested Blizzard, doesn't proc either.
So, no proccing of any DoT - single target or AoE ones (=> no procs from consecration).

Also, confirming that melee and spell procs are independent:
17s - Melee DF proc.
22s - Ice Lanced. Spell DF proc.
29s, 33s, 39s - Melee DF proc.

Any information about whether this procs on Holy Shield or not?

I got the enchant on my druid the other night, and threw it on the mounting vengeance i got on my shaman since I didn't feel like wasting money on mongoose. I went and pvp'd with it for a while, and noticed it being up almost constantly via shocks, autoattacks, and stormstrike. It was also refreshing itself on occasion.

So I myself as an Enh shaman wanted to test this out and see if it would be viable for Mongoose Deathfrost. Since it says your melee attacks and spells proc it. Does that mean you only need 1 of the enchants cause all your melee attacks can proc it? Any who.

What I wanted to test was if Flametounge Weapon Enchant would proc Deathfrost, and it does not. I have recieved multiple times where I proced deathfrost 2 to 3 times in a row between shocks and melee hits.

my combat log read:

Melee hit
Melee Hit
Flametounge
Death frost

Reportedly it does not proc on any dots, only direct damage, so it is fairly useless in PVP for an affliction warlock.

Did some limited testing last night and this morning:
Could not get any procs off of any reflective dam(BoSanc, Ret aura, Holy Shield, shield spike), tested 1 at a time with 6+ mobs beating on me for 5min for each ability.
As stated earlier, no procs off of consecration as well.
Couldn't get a proc off of Avengers Shield or Hammer of wrath either(only aprox 30 hits of each so not extensive testing, but would seem to indicate that if it can proc off of them its using the melee proc rate).

Tests done on lvl 64 humanoid mobs so no parries/dodges/misses:
Melee - Aprox 1000 hit test yielded nearly 4ppm while auto-attacking(no seals, no judgments, no haste effects).

Melee+Judgment of Righteousness - Aprox 600 hit test(judgments+melee hits) also yielded 4ppm, but confirmed that deathfrost will proc off of the judgment, but seems to be using the melee proc rate. Wasn't able to confirm ICD on judgment procs as that test would need to be done on undead/demon to see if exorcism would proc immediately after a JoR proc.

Pally talent 1h spec does increase the dam of the proc and zone wide buffs(for instance the +5% dam buff for controlling the pvp towers in terrokar) also increase the dam of the proc.

Protadin math:

+40 spell = ~ 20 TPS.
1 dmg = 1 Threat
Therefore, for Deathfrost to be threat-superior to 40 spell, it must do 20 dps or better. It appears none of our spells can proc it (Consecration, Holy Shield) as spells, and Judgment procs it as a melee attack as per the post above me. It deals 165 Frost damage with raid debuffs, so to do 20 DPS it would have to proc every 165/20 = 8.25 seconds (7.27 PPM), or near constant debuff uptime.

My guess is, this is a very clever move towards raid homogenization again - with DF, tclap is much less of a benefit.

Has anyone tested with Force Reactive Disk (Force Reactive Disk - Spell - World of Warcraft , the MC engineering shield). I don't know much about spell mechanics, but looking at wowhead, this is apparently a "Apply Aura: Proc Trigger Spell." Where Blessing of Sanctuary and Holy Shield are Apply Aura: Proc Trigger Damage.

Um, I'm going to go on a limb here and guess that the real reason is that they don't want aoe (consecration, AE etc.) to proc these direct damage procs. It would be fairly trivial (mechanics wise) to create a PPM effect for spells.

This. There's already a system in place with spell coefficients, it would be easy to base proc rates on them.

I wonder how this would work for Ret Pally, since Seal/Judgment of Blood are melee attacks, however Judgment of Command is a spell attack.

JoC is still a melee attack (it can proc things like Executioner and Mongoose) it just uses spell hit/crit mechanics.

I think it is actually that way for all Judgements; they just all use different scaling, crit, and hit ratings depending on how baked the devs were when they were designing the spell.

Did 1231 melee strikes against a blasted lands mob with a 1.96 MH (unarmed) and 1.47 OH (haste include). This gives a total of 703 OH swings. Only my OH weapon was enchanted with deathfrost, and I got 38 procs.

Considered as a flat rate, this is 5.4% with a 1.5 base speed OH
Considered as PPM, this is 2.16 procs per minute.

Doing the math on this data, There is not enough information to calculate the rate or PPM from it, since MH procs and OH procs are added together. However, assuming 2.16 PPM, and doing the math with that, we would get
550*(1.5)/(2.8+1.5) = 192 MH hits @ 2.8s each = 537s = 8.95 minutes = 19.3 procs on average
550*(2.8)/(2.8+1.5) = 358 OH hits @ 1.5s each = 537s = 8.95 minutes = 19.3 procs on average
19.3 procs + 19.3 procs = 38.6 procs total, and you got 39, so we are in agreement

Conclusion: Deathfrost has a melee proc rate of ~2.16 PPM.
