The Strategy

Phase 1

Algalon will transform the arena into space and immediately begin attacking whoever has the highest threat. Algalon hits very hard and fast and will cast Quantum Strike very often on the tank so healers need to make sure he remains at full health at all times.

All DPS merely attack the boss the best they can. Algalon can be positioned anywhere as he has no frontal cleave or cone attacks.

After 15 seconds Algalon will use Phase Punch on the current tank every 15 seconds and summon four Collapsing Stars. Once the tank gets 5 stacks of the Phase Punch debuff, Algalon will switch to the second-highest on his threat table, so your off-tank should be ready to taunt and your healers should be ready to change targets as the off-tank will be taking a lot of damage very quickly. Algalon will be Phase Punching the tanks throughout the fight and need to keep switching.

For the stars (little things that look like sparks!), 1-2 DPS should be assigned to killing the stars one at a time. If they are left alone, they will all explode at the same time and wipe the raid. DPS need to make sure healers are ready before a Collapsing Star is killed as the entire raid will take roughly 16k damage, and if the tank is too low on health when a star explodes, he'll die and will very likely cause a wipe. After each star is killed, a Black Hole is left behind (explained later). Stars will keep spawning throughout the fight until Phase 2 and should always be killed.

Every 25 seconds, Algalon will begin casting Cosmic Smash on a random player. A red fissure will appear that everyone has to quickly move away from or they will die instantly. After the Cosmic Smash hits the spot, it will cause some splash Fire damage which seems to be based off the player distance with the impact point.

50 seconds after the initial pull, Algalon will summon three Living Constellations that will damage random players in the raid and have normal threat tables. When a Living Constellation enters a Black Hole, it dies instantly and the Black Hole disappears. A single DPS or probably a healer should get aggro on all three of these and run behind any Black Holes they find. The idea is to kite the Constellations into the Black Hole to kill them instantly. Death Knights are an ideal choice for this as they can stand behind Black Holes and use Death Grip so the Constellations land in the hole.

Every 90 seconds from the initial pull, Algalon will begin casting a 8-second cast spell called Big Bang that is almost guaranteed to kill anyone it hits. To dodge this, everyone but one person needs to enter a Black Hole created by a killed Collapsing Star. Once inside the Black Hole, players will take roughly 1,500 Shadow damage per second and there will be elite adds called Dark Matter scattered everywhere.

Note: If EVERYONE enters the Black Holes and Algalon has no player in the 'normal' realm to target, he will cast Ascend to the Heavens, killing the raid and disappearing. You must have one player eat the Big Bang. A tank blowing *all* cooldowns, a Guardian spirited anyone or dispersioned Shadow Priest are all capable of eating the Big Bang. Big Bang ignores immunity effects such as Hand of Protection, Ice Block and Divine Shield.

Players need to avoid getting hit by these the best they can until Algalon has finished casting Big Bang. Afterwards, everyone is teleported out of the Black Hole and the fight progresses as before. Not sure of this (couldn't find any info yo!), but each Black Hole seems to have their own separate 'realm' so players need to make sure they enter the same one if possible. Entering a Black Hole also resets all threat of the player, so it is advised the currently Phase Punched tank to stay outside and eat the Big Bang. This way, the off-tank can taunt to gain all the threat he had and DPS don't have to worry about getting aggro.

This phase continues until Algalon reaches 20%.

Phase 2

Once Algalon reaches 20%, Collapsing Stars and Living Constellations will despawn and will no longer spawn anymore. Any currently open Black Holes will also dissapear. Algalon will continue to cast Quantum Strike, Phase Punch and Cosmic Smash however.

Algalon will then summon four Black Holes in a square pattern. Every 30 seconds, four Unleashed Dark Matters will spawn, one from each Black Hole. The off-tank needs to pick these up and tank them to the side for the rest of the fight and DPS need to burn down Algalon before these adds pile up and become too much to handle.

When this phase begins, I reckon we swap tanks as the current tank will very likely have the Phase Punch debuff and the off-tank will have a hard time surviving if he has to tank the adds and Algalon together (even the Nab). If you swap once the Black Holes spawn, you'll be given about 45 seconds to defeat Algalon before a forced tank-swap which should be long enough. Players also need to keep alert about Cosmic Smashes as Algalon will still be using this.

Once Algalon reaches 1-2%, he is defeated, all adds and Black Holes despawn.

And we win.
