Stormbreaker

This achievement requires participation on the Isle of Thunder, in the similar way that completing quests on Mount Hyjal and the Molten Front contributed towards Veteran of the Molten Front and the reward title of The Flamebreaker.
Additionally, some achievements require participation in the Troves of the Thunder King scenario.

Isle of Thunder-Your character has to complete storylines styled in the manner of one time, single-player scenarios (Which, in my opinion, is a great way of improving them).

Pay to Slay/It Was Worth Every Ritual Stone (achievement credit)-Shan'ze Ritual Stones can be found from troves on the Isle, drops from rare mobs on the IoT, and some quest rewards. 3 of the stones can be used on Ritual Stones around the Isle.

Thunder Plunder-Troves can be found anywhere on the Isle of Thunder, so check every nook and cranny! Additionally they have the chance to contain a Key to the Palace of Lei Shen, a key that can grant access to the single-player scenario Troves of the Thunder King.

The Crumble Bundle-this weekly quest is interesting in that the Head of the Chamberlain can and its other quest items can spawn in different places, so this is down to timing.

.Loot 10 Golden Treasure Chests in one run-This involves getting the larger chests, so having the camera zoomed out as far as it can go should help. You will also have to jump onto ledges and explore corners for many hidden chests. I believe 3 are found behind God-Hulk Gulkan.

Ready for RAAAAIIIIDDD?ing-This is best completed when there are less people in the area, as crushing the roaches is necessary for a daily (Stage 1 dailies). Why this wasn't called Ready for Raiding IV is beyond me!

When in Ihgaluk, Do as the Skumblade Do-The different life stages of the devilsaur are found in different places, and Kroshik hatches and dies all in a week's time, so it's best to visit Ihgaluk Crag and get a targeting macro so you don't miss him.

The Mogu Below-gu/These Mogu Have Gotta Go-gu (achievement credit)-the Incantations to summon the bosses drop from mobs on the Isle as well as drops from objects and you summon them at their respectable epitaphs.

This Isn't Even My Final Form-It makes sense to acquire the Mighty Loa buff first, seeing as it has a 5 min effect, whereas the Zandalari Potion is 2 minutes, so you can spend the rest of the 5 mins searching the settlements of Trolltonshire Za'Tual for a potion.

Blue Response-When on the daily quest Preventing a Future Threat, frightening the Hatchling S$%^creamers has a chance for a rare, blue-skinned version to respawn and take its place. The quest is obtained during Stage 1.

Platform Hero-A literal platform game, this will take time to get, given that The Swollen Vault is accessed when you unlock Stormsea Landing. Apparently the sequence to complete this changes daily, so it won't be easy to get, and falling down will involve resetting it.

Speed Metal-Killing Shan'ze Electrocutioners gives you the buff when you run over their corpse. A strategy for the fight can be found here. Metal Lord Mono-Han is found after the Thunder Forges are unlocked, in Stage 4.

You Made Me Bleed My Own Blood-When the Possessed Blood spawn and reach Fleshcrafter Hoku (found after the Thunder Forges are unlocked/Stage 4), he will be healed, so having a group is recommended for the achievement, otherwise you'll be dragging the fight out. Avoid AoE spells and you should be ok.

For the Ward!-Hilariously, seeing as we've armed the wards during the rediscovery of the Sunwell, now we must use the perimeter wards at Dawnseeker Promontory/Violet Rise (both claimed through the War Effort) to finish them off. Find a mob, weaken it to just under 10%, and the ward should finish it off!

Boop-The s@#$creamers are found all over the Isle, so finding them shouldn't be too hard. Attacking the Zandalari first will ensure you get credit.

Our Powers Combined-See the achievement page for more information. Guardian Tak'u is found on the Conqueror's Terrace, a sub-zone available on the second stage of questing.

Direhorn in a China Shop-the Beast Pens where the Loa-Infused Bloodhorn is found are in the third stage of questing in the zone. Kite the Bloodhorn to the vase's location, stand between them and wait for him to use his charge ability and jump out of the way so that he runs into the vase!

Zandalari Library Card-Pretty self-explanatory. The main Zandalari settlements are The Beast Pens, Conqueror's Terrace and Za'Tual. Edit: They can also drop from the Zandalari on the Isle of Giants.

Edit: In the Hall of the Thunder King became a Legacy FoS in 6.0.2, although [item=94222] can still drop for all classes allowing the FoS to still be done!

<Name> The Stormbreaker, a must have for any shaman.

It's called Ready for RAAAAIIIIDDD?ing because of the Raid bug commercials where they yell out RAAAAIIIIDDD and then explode.
