Crushing Bones and Cracking Skulls: Defeat Rom'ogg the Bonecrusher after using his Skullcracker ability to kill 10 Angered Earth elementals in Blackrock Caverns on Heroic difficulty. In order to get this achievement you will need to keep 10 Angered Earth elementals alive and have Rom'ogg kill them using his Skullcracker ability. He uses his Skullcracker ability after using the Chains of Woe which brings the whole group to him and roots them in place. The easiest way to do this is have a Mage Frost Nova the adds after breaking the Chains of Woe.
Arrested Development: Allow all three of Corla's zealots to evolve, then defeat Corla after slaying the evolved zealots in Blackrock Caverns on Heroic difficulty. You will need to let the zealots evolve one by one and have the tank pick them up and kill them. It is a very difficult achievement that will be very demanding on the healer since the zealots do a lot of damage as well as having to heal through the bosses damage. My biggest piece of advice is interrupt all of the zealot's Shadow Strikes. They do the most damage.
Too Hot To Handle: Defeat Karsh Steelbender after he has reached 15 stacks of Superheated Quicksilver Armor in Blackrock Caverns on Heroic difficulty. In order to do this achievement your tank will need to kite Karsh Steelbender in and out of the lava puddles. It is recommended that you casually get him up to 15 stacks and not go up to it all at once because it will put too much stress on the healer. Also keep in mind you don't need to kill him at 15 stacks, you only need to reach it during the battle.
Ascendant Descending: Defeat Ascendant Lord Obsidius without any party member reaching 4 stacks Crepuscular Veil in Blackrock Caverns on Heroic difficulty. First, put all pets away before doing this boss as they count towards the achievement and will ruin it for you. Second assign two people to kite the adds around and make sure no one gets close enough to them for too long.
Old Faithful: Get Lady Naz'jar to kill one of her minions with her Geyser ability in Throne of the Tides on Heroic difficulty. The easiest way to do this is DPS one of her adds down to 50% health then have everyone stack on top of each other so the Geyser has a 100% chance to hit the add. Once the Geyser forms under the group stun or CC the add and have everyone run out of the Geyser.
Prince of Tides: Defeat an Unyielding Behemoth while you have the Tidal Surge effect during the Ozumat encounter in Throne of the Tides on Heroic difficulty. This achievement requires you to keep an Unyielding Behemoth alive until phase two of the encounter when Ozumat casts Tidal Surge. After he casts Tidal Surge burning down the Behemoth will be a simple task.
Rotten to the Core: Defeat 60 Disciples within 10 seconds during the High Priestess Azil encounter in the Stonecore on Heroic difficulty. In front of the boss there is three packs of disciples, you will want to pull all three packs and the boss and AoE them all down to easily get the achievement.
No Static at All: Completely avoid the Static Cling effect during the Asaad encounter in the Vortex Pinnacle on Heroic difficulty. The easiest way to get this achievement is to jump right before Static Cling is finished casting. Or you can have a Mage or Priest cast Slow Fall or Levitate on you to make this achievement extremely easy.
Extra Credit Bonus Stage: Collect 5 Golden Orbs in a single visit to the Vortex Pinnacle on Heroic difficulty. There are many different spots that the Golden Orbs spawn in Vortex Pinnacle. The easiest way to do this achievement is after you've completed the instance back track and collect all 5 that you need so you don't hold the group up.
Umbrage For Umbriss: Defeat General Umbriss while he is affected with Modgud's Malice in Grim Batol on Heroic difficulty. When you engage General Umbriss a group of troggs will spawn, containing one Malignant Trogg. The Malignant Trogg can be crowd controlled off to the side until you need it towards the end of the encounter. When you bring General Umbriss down to 15% health you will want to break the CC on the Malignant Trogg and kill it. Once it dies it will put a debuff on General Umbriss for 20 seconds, you will need to kill him with this debuff active. Keep in mind that when you bring him down to 30% HP he will go enraged and the debuff the Malignant Trogg puts on him will increase his damage further, so it is highly recommended that your tank pops his defensive cooldowns when the trogg dies.
Don't Need To Break Eggs To Make An Omelet: Defeat Erudax without letting a Faceless Corrupter begin to cast Twilight Corruption on any of Alextraza's Eggs in Grim Batol on Heroic difficulty. It is very important to slow the adds as soon as possible of them spawning. They will spawn two adds after every Shadow Gale. You will need to kill the adds before they get to the eggs and start channeling.
I Hate That Song: Defeat Temple Guardian Anhuur without allowing him to sing Reverberating Hymn for more than 15 seconds in Halls of Origination on Heroic difficutly. There are many different ways to do this but the way that I've found to work best is to have the tank jump down on one side with another dps and pick up all the snakes. The DPS will focus on pulling the lever as soon as possible. On the otherside a single DPS will jump down while another DPS up top will AoE the snakes and agro them all, causing them to go up top and chase him, allowing that DPS to pull the lever without trouble. Once both levers are pulled someone will need to quickly interrupt Anhuur's Reverberating Hymn spell.
Straw That Broke the Camel's Back: Defeat Earthrager Ptah while mounted on a camel in the Halls of Origination on Heroic difficulty. This is a fairly simple achievement. All you need to do is dodge all of the Quicksands and Earth Spikes to prevent your camel from being killed.
Faster Than the Speed of Light: Complete the Vault of Lights within 5 minutes of entering the Halls of Origination on Heroic difficutly. You have 5 minutes to kill all four elemental lieutenants upon Brann opening the doors leading into the Vault of Lights. You will need to kill the final lieutenant with 30 seconds left on the timer giving you enough time to watch the event when the boss steps out from the door and uses his AoE that injures everyone.
Sun of a.....: Defeat Rajh before he completes an entire recharging phase in the Halls of Origination on Heroic difficutly. In order to get this achievement you will need to interrupt all of Rajh's abilities you can that are interuptable. This will cause him to use as little focus as possible throughout the whole fight. It is also recommended that you use Bloodlust or an ability similar too it in order to get this achievement easier.
Kill It With Fire: Defeat 3 Burning Souls during the High Prophet Barim encounter in the Lost City of Tol'vir on Heroic difficulty. Note: You don't need to do this achievement all in one run. In order to get this achievement you will need to bring the boss down to 50% health to enter the spirit realm. Every few seconds in the spirit realm a soul fragment will spawn that channels a heal on a Dark Hatchling. You will want to move the soul fragments into the fire patches on the ground to transform them into Burning Souls. Once you've done this, kill 3 of them.
Acrocalypse Now: Defeat 20 Frenzied Crocolisks within 10 seconds during the Lockmaw encounter in the Lost City of Tol'vir on Heroic difficutly. In order to get this achievement you will need your ranged DPS to kite the crocs around until 5 packs of them spawn. Once all 5 packs of them spawn you will want to gather them up into a big pile and AoE them down.
Headed South: Defeat Siamat, Lord of the South Wind, with 3 stacks of Lightning Charge in Lost City of Tol'vir on Heroic difficulty. Upon killing one of the melee adds you will recieve the Lightning Charge buff. Note: only people in melee range of the add will recieve the buff upon its death. The buff lasts a short period of time and stacks up to three. The easiest way to get this achievement is to have the tank pick up all three melee adds and DPS Siamat until he reaches 30-35%. At this point you will want to kill all three melee adds and pop Bloodlust or a similar abilitiy and burn down Siamat. Once you kill all three melee adds your main focus should be surviving since the buff will increase all damage taken by 100%.
Ready for Raiding: Do not get hit by Fire Wall in the Glubtok encounter in Deadmines on Heroic difficulty. This is not a group wide achievement meaning it only requires you to dodge the Fire Walls cast by Glubtok.
Rat Pack: Kill 20 Mine Rats during the Helix Gearbreaker encounter in Deadmines on Heroic difficutly. Each time the Lumbering Oaf uses his charge ability on players Mine Rats will spawn around the lumber pile they were smashed into. You will need to kill these Mine Rats in order to get the achievement. Note: You don't need to kill all the Mine Rats in a single run, you can kill all 20 of them over multiple visits to the Deadmines.
Prototype Prodigy: Keep the Prototype Reaper from falling below 90% health during the Foe Reaper 5000 encounter in Deadmines on Heroic difficulty. The easiest way to do this achievement is have the Prototype Reaper sit at the top of the stairs while the group takes care of the Foe Reaper 5000. Keep in mind that if the Prototype Reaper falls below 90% health at any point (even on trash) you will fail this achievement. Also this achievement must be completed the first time you engage the boss, if you wipe and try to reattempt it you will not recieve this achievement.
It's Frost Damage: Allow three Freezing Vapors to cast Coalesce during the Admiral Ripsnarl encounter in Deadmines on Heroic difficulty. You don't need to kill the boss in order to get this achievement, simply let three Freezing Vapors cast Coalesce when Ripsnarl vanishs.
I'm on a Diet: Do not gain more than one stack of Nauseated during the Cookie encounter in Deadmines on Heroic difficulty. Only click the gold glowing food during the encounter to get this achievement. Clicking the green food will give you the Nauseated debuff.
Vigorous VanCleef Vindicator: Engage Vanessa VanCleef within 5 minutes of being inflicted with the Nightmare Elixir. There isn't much advice to give besides move fast upon being inflicted with the Nightmare Elixir. Keep in mind though that you do not need to kill Vanessa VanCleef, only pull her while under the effects of the Nightmare Elixir. This means you can essentially still pull her while doing the Ripsnarl encounter.
Pardon Denied: Defeat Baron Ashbury without letting him heal with Stay of Execution in Shadowfang Keep on Heroic difficulty. The easiest way to do this achievement is to assign three different DPS to interrupt each of the three different abilities that he has. The trick to surviving is to heal the tank instantly after getting out of Asphyxiate since he will only have one health and will start taking damage the moment you interrupt Stay of Execution.
To the Ground!: Defeat Commander Springvale without allowing him to recieve Unholy Empowerment in Shadowfang Keep on Heroic difficulty. This achievement is easiest if you have a Hunter or Priest to shackle one of the adds while the group burns down the other one. Once the first add is dead quickly kill the second one. You will have to rinse and repeat this every 45 seconds when Commander Springvale summons adds.
Bullet Time: Defeat 12 Bloodthirsty Ghouls with Pistol Barrage and then defeat Lord Godfrey in Shadowfang Keep on Heroic difficulty. The easiest way to do this achievement is to tank Lord Godfrey on the lower level in the middle of the room facing away from the rest of the group. When the adds spawn the tank should use an AoE ability to hit them once then turn around and run away from Lord Godfrey to the nearby wall. This will out range the Pistol Barrage ability so the tank won't take much damage and it will cause all of the adds to walk towards the tank and right into the Pistol Barrage.
