Anyone remember the extra achievements in Ulduar? The ones that were just there for fun, not part of the meta achievement for the drake, not related to a hardmode, just there as something to, well, achieve. If you were interested.
I decided to brainstorm some of this type of achievement for the current tier. I didn't add achievements for any heroic-mode only mechanics, because Blizzard seems to keep achievements to be totally possible on reg mode (though it's fine if some are easier on heroic- remember Jaraxxus' achievement?) The exception is, of course, Sinestra. She gets her own achievement because the precedent is there; Algalon had his "Supermassive" achievement.
Some of these are personal achievements, some of them require the entire raid to coordinate extra hard. Some of them are simply rewarded for doing the fight absolutely perfectly, others require deliberately "messing up" and killing the boss in spite of it. All of them are hopefully something to keep your raid interested during boring farm content, or maybe something fun to do a year down the line when you revisit these instances in your heroic t14 gear.
I'm aware some of these might be too easy or too hard. Tell me what you think!
Magmaw:
"Temper Tantrum"
Hit the Image of Nefarian with a chain after jumping on Magmaw's back, then kill Magmaw.
"I Heard You Like Kiting"
Defeat Magmaw while at least 30 Lava Parasites are alive.
Omnotron Defense System:
"Fight Poison With Poison"
Kill ten Poison Bombs while they are in a Chemical Cloud, then defeat Omnotron Defense System.
Maloriak:
"I'm Happy For You"
Do not allow Maloriak to damage with raid with Arcane Storm.
"And I'm Gonna Let You Finish"
Defeat Maloriak while he has at least three stacks of the Growth Catalyst buff from Aberrations.
"Failed Subject"
Kill a Prime Subject, then kill Maloriak.
Atramedes:
"Quick and Dirty"
Defeat Atramedes while using no more than 6 Ancient Dwarven Shields.
"Loud and Proud"
Defeat Atramedes after having each member of the raid go above 75 sound at one point in the fight.
Nefarian:
"Timing Attack"
Kill the three Chromatic Prototypes within 3 seconds of each other, then defeat Nefarian.
"I Heard You Really Like Kiting"
Defeat Nefarian while not letting any Animated Bone Construct refresh its energy.
------------------
Halfus Wyrmbreaker:
"Mostly Pacificst"
Defeat Halfus Wyrmbreaker without killing any of the drakes. The Emerald Whelp pack counts as one drake for this purpose.
"Extra Add"
Damage the Proto-Behemoth below 80% health, then kill Halfus Wyrmbreaker.
(I know the Proto-Behemoth is attackable, I checked last raid... I wonder if it drops any phat lewts if you kill it?)
Valiona and Theralion:
"Just Once Please"
Defeat Valiona and Theralion before Valiona lands a second time.
"Meteorology"
Defeat Valiona and Theralion without anyone taking more than 30k damage from Twilight Meteorites.
(These are the ones you have to stack up for while Theralion is on the ground)
"Cloudy With A Chance of Fireballs"
Defeat Valiona and Theralion without anyone taking damage from Twilight Blast.
(These are the avoidable ones that fall when Valiona is on the ground, that most people just ignore. This would be hard- sort of like the Kologarn eye beam achieve!)
"Spooky Down In Here"
Defeat Valiona and Theralion while having each player in the raid enter the twilight realm at least once.
Ascendant Council
"Flawless Victory"
Defeat the Elementium Monstrosity while neutralizing the following attacks:
Nobody without the Grounded buff is hit by Thunderstorm
Nobody without the Swirling Winds buff is hit by Earthquake
Nobody takes damage from Hydro Lance
Nobody takes damage from Lightning Blast
Nobody takes damage from Eruption
"Spread it Around"
Gain both Burning Blood and Heart of Ice buffs.
Cho'gall
"Thought Control"
Defeat Cho'gall without him gaining any stacks of Twisted Devotion.
"Angk Ungh'fwussht"
Defeat Cho'gall while having Corruption: Absolute.
Sinestra
"Indomitable"
Defeat Sinestra while a Twilight Spitecaller is still alive.
------------------
Conclave of Wind
"Platform Dance"
Defeat Conclave of Wind while having each player visit all three boss platforms at least once.
(This should have been the meta achievement, "Stay Chill" is totally bullshit)
"Secret Shortcut"
Visit the platform with the entrance portal during the Conclave of Wind fight, then defeat the Conclave of Wind.
Al'akir
"Passing Wind"
Defeat Al'akir without any player being knocked off the platform or getting trapped in a Squall Line.
"Airheaded"
Defeat Al'akir without stacking Feedback higher than one stack.
