(Didn't see any specific thread on Deathfrost, but as it's so recently added I felt it was worth collating info).

So... with the release of Midsummer comes this intriguing new enchant. My first thoughts are that it provides an awesome mid-priced weapon enchant for those who don't want to splash out hugely on mongoose/executioner but don't want something as cheap as fiery. Certainly I'll be stocking up on Shadow/Water primals for use on my WotLK levelling weapons. But... how good IS deathfrost, and exactly what does it stack with.

The proc seems to have a 20 second cooldown, and a high chance (heard it quoted as much as 50%). The question is whether a.) these values are correct and b.) if you have two weapons dual wielded with deathfrost on both, is the cooldown shared or separate.

150 Frost damage proc. Apparently this uses your Spell Crit rate to determine crit chance and modifiers (so a Chaotic Skyfire will make it crit more, as will spell/frost crit talents). Can it be resisted? Parried/dodged? Does it use your spell hit?

15% Haste Slow on melee/ranged/spells. This is the kicker. Clearly this makes it a good PvP enchant (depending on procrate), but what exactly does it stack with. I've heard some people say it stacks with Thunderclap/Thunderfury, others say it doesnt. Logic seems to imply that TC+Deathfrost would give 15% caster haste and 20% melee haste... but is there a chance that the 15% and 20% melee haste would stack. Apparently it works fine on raidbosses, so an alternative for small groups without a warrior, but its viability as a Warrior Tank enchant is very much dependant upon whether its slowing effect stacks in any way with thunderclap.

Alas I haven't tried it yet myself, I intend to but I don't have any spare weapons that I can afford to overwrite a mongoose/executioner with. So I'm hoping this thread can be the dumping ground for everyone's findings on the enchant.

I tested it earlier tonight offhand only on a Blasted lands mob and I got back to back procs. So at least for melee there is no cooldown.

I also duelled with it and it seems there are no diminishing returns for pvp.

It is also not a labelled debuff so it's not dispellable.

We have to assume all bosses are immune to it? If not it would be very overpowered. And hmm.. if it procs that much wouldn't it be better than the other caster enchants then?

The melee slow doesn't stack with thunderclap, however does the spell casting slow work on bosses? The lock/mage tank on highking/kael/illidan/twins etc with this enchant could be very nice.

Grabbed a caster friend to test. Attack speed was 2.16 with just 3/3 Imp TC up. I applied Deathfrost and immediately TC'd and the attack speed was the same, 2.16. Therefore, they do not stack.

I'd be interested in how this works with priest self buffs.

Touch of Weakness can proc blackout, so I'd think it would be able to proc this. Things would be interesting if it procced off reflective shield. Permanent -15% attack speed on the rogue/warrior killing me would be much better than +81 healing.

Actually, I'll test this.

Important notice:
Deathfrost cannot be refreshed. So, once the debuff is up, it cannot proc again until the debuff has faded. Even having the proc go off again does not apply damage. You can see this by just melee'ing and you'll see the graphic go off again.

Has anyone tested to determine if this effect stacks with curse of tongues and/or mind numbing poison? If it does, I can see potential applications on fights like RoS and Council, for the rogue interrupter.


If this enchant does not stack with thunderclap, then likely it also would not stack with mind-numbing, but a test would be desirable either way.

No other similar effects stack, so why would anyone expect Deathfrost to be an exception? The stronger debuff overrides all weaker ones in basically every situation I know of.

Just another bit I was curious about, is how much threat the enchant does per proc. Did anyone figure this out yet?

No combat log to prove it, but i have had it refresh itself on the same mob twice just hamstringing some spiders and wolves between bg ques.
