Its a trinket, so no set number of uses... but if Im going to pay 10+g to make one it better have a cooldown of 10 min or less... anyone know?

Cooldown is five minutes.

Great magekiller. But I think its gonna be more like 30g to make.

This is like, alliance's answer to shamans. I am a shaman and I would hate for my initial FS to bounce back and hit me. That would freakin suck.

5 min cool down

This doesn't work with AOE spells (so no frost nova, blizzards, etc). This only reflects directed spells. IMO for PVP, the ice isn't as effective as the fire one, simply because frost mages seem to use more AOE than anything. Fire mages, from what i've seen, tend to use a lot of hard-hitting fireballs. Reflected 1k fireball crit = doomed mage.

Does this work on Frost Shock?  If it does, it will be awesome.  watching the shamans using their cheap frost shock to kite themselves without having cleanse.  I'm sure hunters and druids will love using this.  (You can easily expect a frost shock coming when you are low health trying to run away from them)

i dont care, im posting my comment about the shadow reflector on this.  it rocks.  was in WSG the other day, and i had the flag.  the ally warlock is chasing me, and tries to use the affliction talent tree curse to slow me down, and instead slows down himself!  wicked funny.

Now for the frost reflector comment.  im a druid, and was in another WSG game with the flag.  used frost reflector (i have 2 reflectors, frost and shadow).  obviously, a NE hunter put ice trap right on the flag, and stil had about 6 ppl guarding.  so i grab boots, nab the flag, get ice trap reflected and freezes the whole room.  im outa range in no time with combo 2X speed and them all frozen.  wicked funny. and guess what, happened two more times!  i got hat trick, yay for me.  i suggest having multiple reflector trinkets and a macro to switch 'em around when you're facing different classes (ice+fire for mages, shadow for priests and warlocks) HAVE FUN

well, a "macro" wont do anything.  but you can do this...

make multiple types of these trinkets (fire ice shadow etc) and click and drag them to a slot on your toolbar.  then by clicking on the new slot, you can equip it.  this put a cooldown on all of your items;i dont know, havent checked yet.  but it is a way to switch it without clicking and dragging during battle.

there is exelent addon for fast trinket switching - Trinket Menu

Just seein if anyone has read about Naxxramas. Supposedly Kel'Thuzard, the main boss and most of the rest of Naxxramas are ganna be shadow and frost. This might become more useful come the next patch.....

what a beautiful trinket. great for a dwarf tank like me:) 25 frost resistance is nice.

The ice reflector shares it's cooldown with all other reflectors (fire and shadow). The cooldown is 5 mins and you can have 2 of the same reflectors equipped or mix it with another reflector (ie. 2 ice or 1 ice and 1 shadow etc). Don't try to use the reflectors at endgame PVE bosses because it won't reflect their casts and the only bonus you get from them there is the + resistance. The reflectors are GREAT for getting more resistance without gimping ur gear in PVE or ofcourse for their reflections in PVP.

i got problem with this thingie, i come to mage, ambush, turn on ice reflector, he casts frost nova and im frozen.... its some new bug or what... any suggestions?

Finally made one, diden't had to buy anything!
This is how I got the mats, maybe helpful.
-------
Blue Sapphire - fished from floating debris in Stonetalon Mountains or mined from Mithril and Thorium-veins (a Engineer should also be a Miner!).
-------
Icecap - got these from a friend that's an Herbalist (ok that's no helpful xD). Looks like swamp-Elemental-monsters drop a lot herbs! To see such a monster go http://wow.allakhazam.com/db/mob.html?wmob=14231
(this is a rare mob)
-------
Frost Oil - sent one of my friends mats (use Evergreen Pouch to get herbs, go http://thottbot.com/?q=1716 to see start quest getting this item) to make one and got another Frost Oil in that Morrowgrain-quest when handing in ten Morrowgrain to the guy in Darnassus.
-------
Essence of Fire - gathered in Un'Goro, Fire Plume Ridge. This took some time tho'. Also gathered some Thorium there.
-------
Truesilver Transformer - gathered the Elemental Earth and Elemental Air in Arathi Highlands, Truesilver-veins I find once and awhile being on adventure. It use to be some veins of different kind behind Stormgarde Keep (what is it called..?) in Arathi Highlands aswell, on the cliffs at the sea.
-------
Thorium Widget - I find Thorium now and then as with Truesilver (like in Winterspring or Un'Goro), Runecloth drops from a lot humanoids all over Azeroth, like satyrs in Felwood and Furbolgs in Winterspring.

Better to do this than use 50-100g getting mats!!

if you buy the stuf from AH uits gona cost 32g

I got the recipe for this and im looking forward to engineering 260 like i could make it =P
its going to be great in BG against Frost mages

This trinked (and the other refelctor) will become less usefull with the comming of TBC. the new tool tip now says that it might sputter on players that use it above lvl 60.

I also like to point out that they don't share cooldown! you can use the shadow/fire/ice reflector at the same tine (only two of them ofc)

I am wondering, becouse thottbot doesn't say these devices share cooldown with it own kind, so it just might be that you can built 2 of them and have 10 sec refelction time! i don't know this for sure but i looked at the jumpercables and they do share cooldown with its own... it just might be.... i am gonna try it out by building a 2nd ice refelctor. if they do share cooldown with it own kind than i can always sell them:D

still the frost resistance will be great

I am at a 53 level on my first character and a guildy gave me this item, cuz he's got 15 or so trinks trying to help me out. i am not engineer, that means i can't use the item? says my skill level not high enough?

if this is the case which i think it is, is the item hard to sell/impossible, cuz an engineer would just make it for themself.

"Chance to Fizzle against players above level 60."
Fizzle = don't work

SO, does that mean it won't work on mobs either? or just players?

When it fizzles, you just resist the reflector buff and nothing happens, so it is dependant on your level, not the enemy's. I've had the frost reflector long before TBC and I've never once seen it fail, but I just made a shadow reflector recently and its already failed 5 times out of the 10 or so times I've used it. Gnomish mind control cap hasn't been working too well either lately...
