I've searched everywhere but yet I wasn't able to find any serious calculations on Icy Chill. If I simply missed the thread feel free to nuke this one.

First off, I'm completely helpless when it comes to maths, so I'm not able to provide you with any solid calculations at this time of history (well, I could, but it'd be wrong and... wrong).

What I'm trying is to get is a simple comparison between Mongoose and Icy Chill for tanking usage - the overall damage reduction (I'd like to ignore the TPS gain from Mongoose as it's not enough to make a significant difference in my opinion).
As I said I'm not very good in anything that requires any calculations, so I did what I was able to and beat on one of those blasted land mobs for several hours; with a lvl 13 sword and Icy Chill (Autoattack only)

Within 11682 swings it procced 495 times - every 23,6th swing , aka 1.7 ppm. The weaponspeed was 1,50 and the procc itself ("Chilled, 5 seconds, ... increases time between attacks by 25%") doesn't seem to have any cooldown as it sometimes procced twice within 15 seconds.

So... Mongoose provides roughly 4,8% dodge and 240 armor for 15 seconds.
At this point I'm completely lost. I'd appreciate any help with the calculations here; I found several formulas for the uptime and things like that, but to be honest, I'm quite sure I'd even mess those up.

Thanks in advance.

edit:
I'm not 100% sure if it can apply to bossmobs, but I wasn't able to find more than anecdotal evidence on the web.

Hi there, first post here, so please be gentle


According to some comments on thottbot, Icy Chill does not stack with Thunderclap.

Assuming the "reduced effect against level 60+" (more on that below) makes it less than 20%, and you have a warrior with Improved Thunderclap in your raid, this enchant definitely isn't worth it.


Edit:
I just went ahead, enchanted a weapon and did some testing against a level 70 player and came up with the following results:

The tooltip says "25% weapon speed", but this is not true, similar to Crusader.
Normal attackspeed of the victim was 1.80, debuffed 1.56.

As far as I know weaponspeed is calculated with
1.80 / 1+x = 1.56

1.80 = 1.56 * 1+x

-> Icy Chill modifies attackspeed by ~15.4%.

But you might have noticed, the attackspeed actually went *down*. It should have gone *up*, right?

I tried to confirm the faster attackspeed with Quartz' swingtimer, and the mage really hit me faster than before.
I also have some screenshots of the character screen and a very clean part of the combatlog (no parries, just hit, debuff, hit, debuff fades) should anyone be interested.



Next I tested (3/3 Improved) Thunderclap, and attackspeed went up to 1.88, so it does stack - in PvP at least.

Wouldn't their be an extremely high chance for the proc to fizzle on lvl 73 bosses, or are you think along the lines that this spell was overlooked for level scaling?

I played around with the trash shield from naxx with the slowing proc @ 70 a bit (Stygian Buckler - Items - World of Warcraft), it used to be godly @ 60 for duels (and for paladin kiting the zombies on Gluth) etc but it just never procs when lvl 70 players/mobs are attacking you.

It would be quite strange to find icy chill is actually good for something thesedays since it's always been a bit meh due to it's lowish proc rate.

What is your +dmg at in tank gear anyway? I find it hard to believe you couldn't do with more +dmg on your weapon (so you can wear more warrior mitigation plate and/or sustain higher threat) unless you're in full T5/T6 gear.

Wow if you're right, I wonder how long this bug has been around. An enchant that gives haste to your enemies is pretty hilarious

I would like to see screenshots just to ensure you're not messing with us.

That's funny as hell. I wonder if it slows at level 60, and the amount slowed gets to a negative value as you level such that at 70 it hastes, or if it's simply a negative value slow at all levels

Indeed that's a pretty hilarious bug.

This makes the Warrior hitting me with his Deep Thunder enchanted with Icy Weapon in AB even more hilarious.

Could anyone confirm this?

I kind of don't want to use a Sun Eater with +15% haste on bosses..

It looks like your testing confirms it pretty well, as long as the debuff is applied to the boss I see no reason not to expect it to haste them.

Could it be caused by some kind of miscalculation when they tried to limit its power for TBC? A lot of enchants got scaling so they get progressively worse as your level and the targets get higher. If they tried to implement some scheme to reduce the reduction speed the higher level you go could it be borked and going into negatives at high levels, therefore working out at a haste boost?

Has anyone yet been able to test this in the 2.3.2 PTRs?
Patchnotes say that it will work as intended now, but I'm curious if that means it will work on lvl 60 mobs and be crap vs. lvl 73 (as intended) or if the effect will be the same vs. everything.

This may be a long shot. But when I made a character at a mate's lan party (he had set up a private server), we edited the characters to level 250 to have some fun in instances. But when we gave them haste gear, the attack speed went from 3 seconds up to ~20 seconds. I don't know how they have implemented haste, but at extreme levels it turns negative.

Private server or not, his conclusion seems right, but what I was asking for are the changes in 2.3.2 and I'm quite certain you don't have any not yet released game versions on any private servers

Nevermind, someone posted about it earlier in the thread, my apologies.

Probably the "reduced effect against targets higher than 60" gets reduced so much it goes negative

We used to use icy chill for a long time when we did not have a thunderfury. I hope this is a recent bug.

Actually I'm not sure, what you're talking about. The +haste effect is a known bug and what I wa asking for is refering to the 2.3.2 patchnotes that say, that Icy Chill is working correct now. Unfortunately I wasn't able to get the reagents today so eventho the PTRs are up now, I can't test the "fix".

This is not about a know bug on live servers - it's about the fixed Icy Chill on the PTRs so please stop discussing about know and fixed issues...

If the enchant is on a GREY (read: not soulbound) weapon, give it to a warrior and have him test it on you in a duel, with and without TC.

Mh good idea, I'll give it a try, but don't boss mobs have other rules for -attackspeed caps?

Update
Well, at least on players it doesn't stack
- without debuffs: 3,6
- Thunderclap: 4,32
- Chilled: 4,14
- TC+Chilled: 4,32

Could still be worth a thought if it's still more viable than Mongoose in terms of damage reduction, assuming no warrior is near to apply TC.

I suppose if you wanted to snag a second Hammer of Judgement and throw icy on it, you could (assuming you wouldn't have spriests/boomkins waiting to garrote you for it), but I can't really think of anything that hits like an absolute freight train in any content for which you wouldn't have a warrior on-hand. Losing 10% of your spell damage might well make the difference on whether or not you're going to be able to hold mobs off your t6-level DPSers.

That was really the problem I had with my prot paladin that caused me to eventually reroll - starting at the t5 level, you either stack enough spell damage to establish decent aggro, or screw it all and go for pure tanking gear... and be unable to hold single-target aggro on trash pulls. But I digress.

Let me know what kind of PPM you get against 73s, assuming you get a chance to test it. Offnight kara run for alts might be a good opportunity. ~1 PPM isn't going to be enough to make it defensively better than mongoose.

Right now I can't get all the mats within the next 5 minutes until the raid starts and I don't think I'll use a grey sword for testing in TK.
I was just wondering if the Battlemaster-Enchant heal is affected by Righteus Fury so I'll play around with it a little bit (global threat yay!) but that's really off topic.
