We completed this fight with 2 tanks, 6 healers and 17 DPS, but similar raid configurations may work just as well.
The council is a three-phase encounter and you face a total of 5 opponents. In the first phase, you're up against Ignacious, a fire elemental Ascendant Lord, and Feludius, an ice elemental Ascendant Lord. In the second phase, you face off against Arion, who's an air elemental Ascendant Lord and Terrastra, an earth elemental Ascendant Lord. In the third phase, all four entities combine into an Elementium Monstrosity, which combines all four elements in one.
While the first two phases require near perfect execution, the third phase is definitely a soft enrage DPS test. As soon as one Lord in both phase 1 & 2 hits 25%, you'll trigger the next phase, but you want to make sure both Lords are equally low before doing this each time, as the Elementium Monstrosity starts out with a combined amount of health of all four lords. In short, getting all four Lords as close to 25% as you can gives you the best chance of defeating this encounter.
Ignacious and Feludius will be your first opponents, and as you can probably tell as soon as you engage them, their abilities are meant to counter each other.
Ignacious should be tanked on one side of the room, surrounded by a tank and melee, while Feludius should be tanked away from the raid, with ranged raid members loosely spread out across the room.
This is because of one of Feludius' abilities - Glaciate, which deals Frost damage to your entire raid but deals less damage the further away you are from him. As such, your ranged raid members should be assigned to DPS him while your melee are safe on Ignacious.
You'll soon notice that each Lord occasionally puts a debuff on random raid members - Feludius has Heart of Ice and Ignacious has Burning Blood. These deal increasing damage to the target but are very vital to the fight, as they give nearby raid members a buff that increases their damage done to the opposing Lord. Players with Burning Blood should make sure to run through the ranged raid members to give them increased damage on Feludius, and players with Heart of Ice need to join the melee pile to give them increased damage on Ignacious. These can be dispelled, but you should give it 10-20 seconds before doing so.
Heart of Ice is especially important whenever Ignacious is about to cast his most devastating ability - Aegis of Flame. This gives him a shield that absorbs a million damage and he'll start channeling Rising Flames, which deals increasing fire damage to every raid member. To interrupt Rising Flames, his shield needs to be burned down asap. Letting too many ticks of rising Flames go off can easily result in a raid wipe. If needed, have ranged help out with the shield, but make sure they go right back to Feludius afterwards so you bring their health down equally.
Ignacious will also occasionally leap at a ranged target, which knocks everyone around the impact point away. On his way back to his tank, he'll leave a trail of flame on the ground. While I always preach not to stand in the flames, this one is actually USEFUL. This is why: Feludius has a Waterbomb ability, which basically looks like small water missiles flying through the air. When they hit a raid member, he'll get a Waterlogged debuff which reduces movement speed.
Running through Ignacious' flame trail clears the waterlogged debuff and NEEDS to be done by everyone affected. Shortly after casting the Waterbombs, Feludius will cast aforementioned Glaciate, and any player that still has a Waterlogged debuff at that time will get frozen in an ice block and take extreme amounts of damage. This is healable, but it's not something you want to happen.
Feludius' last ability is Hydrolance, which deals big single target damage to a random target and should be interrupted. Make sure your ranged raid members and the Feludius tank watch out for this. Ignacious' last ability is Flame Torrent, which is a channeled cone AoE spell that deals major damage. To counter this, don't be in front of his face unless you're the tank.
To recap: In phase 1, interrupt Rising Flames by burning down the Aegis,power up your raid members appropriately by running near them when you have a debuff and clear Waterlogged debuff by running through the flame trail. Once you get one Lord to 25%, the next phase will trigger. It's vital that both Lords hit 25% at about the same time.
Phase 2 will greet you with Arion and Terrastra, which also have mechanics that counter each other. Ranged raid members are more effective on Arion, as he likes to teleport around the room, so leave your melee on Terrastra. As soon as the fight starts, Arion will summon a cyclone that'll move through the room and Terrastra will summon a gravity well. Hitting the cyclone will give you a sort of levitate, while standing in the gravity well will give you a grounded debuff and clear your levitate.
Both of these are very important as both Arion and Terrastra have very devastating ultimate abilities that deal about 100k damage. They'll alternate in casting these about once per minute. Terrastra has Quake, which can be countered by getting Levitate from the cyclone and Arion has Thundershock, which is cancelled by getting grounded from the gravity well. If you don't have the right debuff at the time either of these are cast, you're very likely to die. The wells and cyclones are summoned in random spots around the room and like to move on top of each other, so make sure to get the appropriate debuff early. They always alternate in their casts - so if you just survived a Quake, get grounded to survive the impending Thunderstorm.
There's one exception to the "get the debuff as soon as possible"-rule, and it's called Lightning Rod. Arion will randomly bestow 3 players with this debuff, and they'll have a yellow arrow over their heads. Players with Lightning Rods need to get out of the raid immediately and hug a wall away from anyone else, since Arion will cast Chain Lightning at anyone affected with Lightning Rod after 15 seconds. If any Lightning Rod is still near people at that time, you'll probably have a few deaths.
If you have Lightning Rod and it comes down to having the choice between being near anyone else or not getting your appropriate grounded or levitate debuff, always leave the raid. You can survive a Quake or Thundershock, but if you're firing off a Chain Lightning in the raid, there will be deaths.
Almost as important is Terrastra's Harden Skin ability, which makes him deal double damage and take half damage. This cast can and should be interrupted whenever possible, but if you fail to do so, have your ranged help out on Terrastra to burn his shield down. Lastly, Terrastra will occasionally cast Eruption, which will look like a few spikes burrowing in the ground, and after a few seconds the spikes will impale anyone still in the area for about 50k. Melee should be aware of this, although it's not the end of the world to get hit by it.
Again, the goal in phase two is to bring both Lords to 25% at the same time. If you execute this right, your Elementium Monstrosity should rise up with about 25% health left, which translates to approximately 18 million health.
Phase 3 is the burn phase and any kind of bloodlust should be saved for this. The Monstrosity will consistently spawn water puddles at his feet that kinda work like Defile on the Lich King, except the puddles expand when the Monstrosity stands in them, not your raid members. Aim to keep the Monstrosity towards the middle of the room so your casters don't have to consistently move to keep up with it. The middle area will be covered in puddles at the end, but that way you get the most DPS on it.
Throughout the whole phase, the Monstrosity will use Electric Instability, which is basically a chain lightning that deals more damage the longer the phase goes on. Eventually, your raid will just die to this, so you need to kill the Monstrosity before Electric Instability becomes overwhelming.
It has two more abilities that it'll use occasionally - Lava Seed and Gravity Crush. Lava Seed looks like little flares of fire hitting the ground, and shortly after they do so they'll explode in a little fire patch. This is the bad kinda fire. Don't stand in it.
Gravity Crush will lift 3 players up into the air and trap them in a gravity bubble. They cannot act during this and will take major damage in the bubble, so healers need to concentrate on them. When released, they'll fall to the ground and also take fall damage when they hit it. It's easy to let people die in this but important not to, with current gear level you need every bit of DPS you can get.
If you have enough DPS to defeat the Monstrosity before your raid collapses, it's more or less a tank&spank phase. This might sound like a complex encounter, but since the abilities all play off of each other, it'll be a lot easier once you engage it. Good luck and have fun!
