Glory of the Firelands Raider

This message plus the mount itself will be sent to you through mail from Malfurion Stormrage when you complete this achievement.

Champion,

When the world's strongest rose to the rallying call of the Avengers of Hyjal,
you stood among the very greatest of them, the best and bravest who dared all in that maw of fire and hatred.

It is for this reason that I ask a boon of you:

A clutch of Millagazor's eggs has been discovered, tainted by the otherworldly vileness of the Twilight's Hammer.
Rather than destroying what remains of her brood, it is my hope that champions such as you, through strength of character and force of will, can tame the ill-fated hatchlings, offering them lives as noble steeds and companions rather than doomed monstrosities.

Will you honor my humble request and take this egg, to raise it as your own...?

Malfurion Stormrage

Probably for the same reason Bane of the Fallen King wasn't included in Glory of the Icecrown Raider (10 player), likewise the 25-man versions: he's likely significantly more difficult than the rest of the bosses.

Hello! Decided to drop a full guide on how to get this achievement for you all! I hope you find it helpfull.

I will exclude all Heroic:... achievements since they speak for themselves. You need to clear 5/7 on Heroic difficulty to get this achievement.

Death from Above
Setup;
One main-tank
One "DPS-tank"
Two healers
Eight DPS

We send up the Main-tank along with a healer and three DPS.
The DPS-tank downstairs is merely a DPS warrior or DPS Death Knight, and his/hers only duty is to keep the Drones -away- from the raid and away from AoE.

Damage the drones to about 50% on the ground. Once they go up, the group upstairs priority is to kill these as soon as possible. Rinse and repeat until Phase 2 begins.

When Phase 2 begins, simply stack behind the boss and nuke her down. No Drones should be active at this time and if there are, make sure they DO NOT die.

Do a Barrel Roll!
This achievement requires you to dodge the four main abilities in the encounter.(This is NOT individual, this is raid-wide.)

The abilities are :
Brushfire : Spawned by the Flame Druids along the outer circle of the room. This -CAN- be interrupted, and should be.

Lava Spew : This is done by the wyrms that appear from the ground, they will turn around 360 degrees in a semi-fast pace and spew a large cone of fire out of their mouth. The best way to approach this is to keep as long away from the wyrms, as possible.

Incendiary Clouds : These are lethal clouds that will spawn along with the rings for the flyers in the encounter. The best way to approach this is to make sure the flyers know what they are doing. Class and Spec choice is very important here aswell to counter the fourth ability. We kept two Fire Mages flying at all times, but Balance Druids may work just aswell.

Fiery Tornado : This is pretty much your "Berserk" timer. Unless the boss is dead by now, theres a high chance someone will make a mistake and get hit once by the vortex. I recommend popping Bloodlust when both the flyers are up in the air with well-enough stacks.

If you do end up hitting the Fiery Tornado phase there are a few safe-zones in the very outer spots of the ring

Share the Pain.

A very easy achievement, since the boss has a very small healthpool, this should not be a problem for your raid.

The achievement is built on that no member of the raid can suffer of [Torment] more than twice during the encounter.

Getting Torment is awarded from soaking the crystals that appear (which must be done.)

How we did it :

Group up your raid in pairs of two, lets say Billy and Rob takes the first crystal, Kim and Josh takes the next, Timmy and Jimmy the next one and repeat.

HOWEVER. This achievement comes with a little twist. After soaking a crystal your awarded with the de-buff [Tormented] which if, stood nearby another ally, you spread this to them, making them take another Torment de-buff.

Keep the raid away from eachother to ensure noone gets unfortunate Torments. Easypeasy.

Not an Ambi-Turner

This achievement is very easy now in MoP.

Nuke the Right Leg with Heroism, causing enough damage to his leg will make his armour break. Try to steer him over as many active volcano's as you can. Good communication is key to this achievement.

Bucket List

A tedious achievement because you need to clear so much trash (!).

In essence, it's a fairly easy achievement.

I suggest you take the following route :

Engage Shannox where he spawns and move him to the wall beneath Beth'tilac's lair. This will check the Beth'tilac's Lair part of your achievement. Now go to the Path of Corruption which is located just behind Beth's lair (shown portal on the map.) After this is done make your way to the entrance of the raid-instance until you see Flamebreach checked on your achievement. Start moving back to Shatterstone, make a quick turn-up slightly half-way up the path to Rhyolith's platform until The Ridge of Ancient Flame is checked. Now lead the boss to Shatterstone and finish him off.

Only the Penitent...

Easy achievement but god it can be tedious if someone makes a mistake.

You want to make two groups, consisting of three people in each group (role/class doesn't matter.)

Three should move to the left, three to the right. The Flame Druid will cast an ability called "Kneel to the Flame!"
When this cast reaches it's end, every member that is placed onto Fandral's platform must Sit (Press "X" or whichever key you have it bound on.)

Once reaching the walls to the left and right of the Flame Druid you will see a big Flame Orb on both sides aswell as three small fiery-pools beneath it. Sit in these pools and make sure all six are at their position. Once that is done, remain in sitting position until the Flame Druid casts a new Kneel to the Flame!

All six members should press the orb simultaneusly and voila, achievement!

I hope this guide proved usefull, do not hesitate to add things or correct me.

Good Luck, Merry Christmas!
