On Hagara the Stormbinder, when the Iceshards starts rotating around the room, Ice Block works & as they are coming towards you, Blink will make you avoid being hit.
Invisibility did not work to dodge any mechanic on that encounter afaik.
I tend to keep Ice Block aswell, if an Ice Tomb is about to form on me, I just pop IB while it's still in the air, when it's falling down, it's too late & atleast this way you can tell your raid to focus the other crystal first or just stay alive longer as you won't take damage untill it runs out. Obvious but still worth mentioning I believe.

On HC Morchok, you can spread your Combustion on both mobs right as the split happens. This requires perfect timing however. Your window of opportunity is less than a second.

Just a warning to any mages that may go arcane on Zon'Ozz - it seems from our attempts last night that the debuff time reduction on mage armor is causing the Disrupting Shadows to detonate even if it is not dispelled.

I had no such problem in our attempts and eventual kill last night.

I think some folks were asking if Ice block worked on zon'ozz's void ball - it doesn't. When I tried last night, it went straight through me.

Hello, Can someone please explain how can combustion be used on every HoT ?
i'd appreciate any kind of help to squeeze that extra dps in.

I think that you confusing Cauterization and Combustion.

I think that Valarauca means that with 4T13 we can have a Combustion for each Hour of Twilight, meaning by this that we can use it to avoid the dps lost at this moment.

It might keep your dps higher for that particular moment but you aren't actually increasing your overall dps. You're just moving the point at which your Combustion increases your dps. If anything lining it up for HoT rather than when you grab a big Ignite is probably a dps loss overall.

I'm not confusing them, I think Valaucra was. Obviously you would have Combustion available a lot more on Ultraxion, but there is really no relation between Combustion and Hour of Twilight in any way, except if he ment to give it as a rough timeframe. The real connection is between Cauterize and Hour of Twilight, where the mechanic helps immensely with the fight, thus I assume he was refering to that.

To clarify, Cauterize allows you to soak the Hour of Twilight instead of a tank, or any player with a defensive cooldown (Shadowpriest, Hunter). It should be available every time the HoT is cast.

Regarding Hagara, it was well known Pally/DK could Bubble or AMS and cross the Ice Bubble threshold and stay inside, among other ways. Mages too appear to have a way.

The trick appears to be needing to be mid-cast of something whilst you cross the threshold. This is easy for a Fire Mage to do with Firestarter and Scorch, half way through a Scorch cast pop inside. I confirmed this works reliably tonight not just for my Mage, but also for our Resto Shaman using their equivilant movement-while-casting ability too (Spiritwalker's Grace).

I tried Blinking in/out pass the barrier, but that didn't reliably work. Casting seemed to do the trick every time.

This is obviously much more useful on Heroic, whereby completing the Frost phase takes several laps. Furthermore, you will never have to move, even when targetted for Frostflake and even if a Frost Patch is directly under you, as standing in the patch itself does no damage.

Though not mage specific, I was also able to confirm this on Monday actually on my Hunter alt when I switched to Aspect of the Fox and Steady Shot cast into the bubble.

Correct. It also means you are free to damage all 4 frost pylons without any risk of death. There are a bunch of ways to exploit the bubble. Talented Stampeding Roar, talented Sprint, etc. That phase isn't all that hard on heroic and most guilds killed it legitimately the first week. However now that these exploits are well known, that phase has become a joke.

Dont rely on them, they are sure to be fixed soon.

This has been fixed and casting scorch doesn't remove the debuff anymore aswell.

In addition to this, on Heroic Hagara in the Frozen Tempest phase when you get the "Frostflake" debuff on you, you can dispel it yourself with iceblock but it will still leave the patch of ice on the floor, so you still have to run out of the group off on the side before doing so. This is useful if your healer isn't dispelling you fast enough or can't dispel you.

And on the lightning phase, after the add dies you can still act as a conductor for the lightning (as in it will pass from the person in front of you, to you, to the person behind you) with iceblock up. In 25 man mode they kill the add on me and since I get hit by the lightning much more than other players, it helps a lot with survivability.

Not surprising, but good to know that blink does work. I was not brave enough to "experiment" at the risk of dying.

Has anyone tried cauterize on this particular mechanic? I know that players can be killed if in the vicinity (rather than in physical contact with) the ice wall, so I would imagine that the damage would "tick" more than once, rendering cauterize useless, if I were to venture a guess. I'm just checking to see if anyone has tried it (and the success/failure of doing so).

Yes, it hits multiple times, so you will not be able to walk through and expect cauterize to save you.

Some tips i use on hagara 10 HM frost phase

As mage fire it's very easy to survive a long time outside the bubble without any heal or dispell.

First of all like someone said before you can blink through the frost wave which allow you to remain on the same crystals(blinking counter-clock) and to answer to the most scared of you i manage (to test and succeed..yeah lot of wipe helps) to get through the wave with any speed effect(i'm worgen) and evocating right after cauterize proc(do not do this normal or slow speed the damage may tick two times)
If your blink is on cooldown and you are stuck in an ice pacth you have to run in the bubble to pass the wave(dont get too far from the center a this time because you cannot blink every wave)
About the dispell of Frostflake you need to get Molten Shields from you fire tree, with your mage ward up when you get the debuff you will be dispelled and under blazingspeed by taking damage from watery entrenchment(damage aura in the bubble) at this point you could use your speed to avoid the wave by getting quickly in the bubble. If you get the debuff two time in a row... well iceblock is the only way to survive without any help.

hope this is clear and understandable

Working on Heroic Madness, does anyone know if it is better to living bomb 3 adds and then start aoeing like a lock or just straight aoe with Blast Wave, Flame Strike, Dragon's Breath, etc?

That depends on the other aoe your raid is putting out. We drop the 2nd parasite on the arm so we can cleave it with the bloods and the arm. I like to impact spread a living bomb to the adds, fishing with blastwave if necessary and then just go into blizzard for the massive spellweave procs.

Does blizzard proc spellweave more than flame strikes and AE?

I wouldn't think so, but it's likely the best option if bloods have less than say 5 seconds left to live, where setting up AE is not practical as fire.

For those looking to start hUltra as fire, you will still die from hour of twilight if you ice block with the debuff Looming Darkness. In my hUltra attempts tonight I had attempted to use cauterize for an hour of twilight then ice block another one, but died when I was ice blocked.
