Ulduar 10 - Mimiron aka Even Worse Than Council

Phase1: Leviathan MKII

Ranged should spread out around him just outside the circle of mines. Melee other than the tank should group up behind the MKII inside the circle of mines. He will cast plasma blast every 45 seconds. All healing should be on the tank unless someone is likely to die otherwise. Shock blast usually follows closely after plasma blast. The tank should run directly away from the front of the MKII and then reengage along the same vector after the blast, and hopefully face him the same direction.

Ranged DPS/Healers who are hit by Napalm Shell do not need to move after being hit. The flame effect is only graphical.

Healing on this phase is priority on the main tank, then people hit by Napalm Shell.

This phase requires a melee tank.
Phase 2: VX-001 Anti-personnel Assault Cannon

Ranged can stay at a distance from the boss and everyone should spread out equally around the mimiron, as soon as the mines have despawned (be careful - sometimes mines appear to despawn but are still active).

Rapid Burst does minimal damage compared to the other attacks, but that deals damage to all targets in front of VX-001. Rocket Strike causes a red target to appear on the ground. People must move out of this target within 3s or they die. Only one rocket is fired each time in Phase 2. As soon as the dps observes that the VX-001 casts Spinning Up, everyone must move behind it. Standing in front of P3Wx2 is instant death.

During the Laser Barrage melee should stand at the edge of the cannon's hit box as meleeing from the center can move you into the laser barrage.

Healing in this phase is mostly AoE.

This phase is untanked.
Phase 3: Aerial Command Unit

Everyone should move into one third of the room, as marked out by the lines on the floor. The Healers and ranged except for the ranged tank should be in the back middle as far away from the bot spawns as possible. A warrior can use Spell Reflection on the Plasma Balls throughout the phase and maintain good threat which will endure into phase 4. This avoids most of the damage from the Plasma Balls and allows proper allocation of a DPS class. The ranged tank needs to immediately pick up the boss. The melee tank(s) should start picking up the smaller bots that start spawning around the room, staying away from and killing the Bomb Bots that the Aerial Command Unit drops. He can be seen casting "Bomb Bots' when he drops a single bomb bot to the floor below, it will then chase a random player until killed or meeting with that player and exploding. Bomb bots can be slowed. The following macro can be used by DPS, Healers and even Tanks with instant ranged attacks to ease the burden of bomb bots. With the raid as a whole using it bomb bots can be destroyed easily before they reach the raid.

Alternatively a plate DPS can stand under the Command Unit and taunt the Bomb Bot as it lands. The bot will move to them and explode. This damage is easily sustainable (25 man) with fire resistance and healers aware of when the bot is incoming. The rest of the raid should stand back from this bomb soak with melee moving in when the Command Unit is grounded. Be aware that if you move in while not on full health you may be caught in the blast of the last bomb dropped before grounding so hold on for a heal before moving in to DPS. No bombs will be dropped during the ground phase. This approach will allow more predictable healing of bomb damage and save DPS time trying to kill it (as it will kill itself).

The Deadly Boss Mods addon is very useful during this phase. It will automatically change the loot setting to Free For All during this phase and will return it to its previous setting at the end of the phase. This is so electromagnets can be picked up by melee. They drop off the Assault Bots. Once picked up, this item should be used underneath the Aerial Command.

Melee dps should be focusing on the small bots until he is pulled down by the electromagnet. At that point all dps should be on the Aerial Command Unit. Ranged dps should be on the bombs that spawn under the Aerial Command Unit and on the Aerial Command Unit otherwise.

Healing on this phase is focused on the range tank and melee tank(s).

This phase is range-tanked.
Phase 4: V-07-TR-0N

Each of the previous phase's targets have their own health pool and can be targeted separately. All three targetable sections begin this phase at 50% health.

The main tank needs to pick up the MKII the same as in Phase 1. The ranged tank needs to pick up the Aerial Command Unit the same as in Phase 3. From what we could tell, there is no threat reset between the phases. The VX-001 remains untanked.

The raid should stand either directly behind or directly in front of the main tank. Ranged should be outside the land mines, Melee should be inside.

Due to the timing of the cooldowns on the current live realms, the first and third shock blasts happen very near in time to the P3Wx2 attack from the middle section. It is essential that the tank move away and approach back along a vector that does not pass in front of the VX-001. The P3Wx2 seems to start to the side of where the MKII is facing. Everyone should move behind the VX-001.

2 Rockets spawn at a time during this phase. They are still a one shot kill.

Dps should be split up between the 3 sections. All sections need to die within 10 seconds, else they respawn. Melee cannot reach the aerial command unit.

Healing should be split up between the Leviathan's damage on the melee tank, the Aerial Command Unit's damage to the ranged tank, and the raid damage done by the VX-001. The Leviathan will no longer Plasma Blast the melee tank or Napalm the raid, and the VX-001 will no longer Heat Wave the raid.

I think this will definatly be a boss people will have to read up on and watch the tankspot video on this as well as it seems extremely intricate.

This is going to be one fun boss, If you are online at all try and get people to register on the forums or even visit the forums to try and watch this video, because this is going to be difficult, tankspot look like they have some huge dps as the bosses go down in like 3 minutes or something.

im looking forward to this boss as i havent done him before gona be tough but we can do it!

Wow i just watched the video, this is truly going to be the toughest encounter so far but after a few attempts im sure all of us will be so familiar with the tactics that it wont be that much of a problem.

Mmiron is teh lose

We got the majority of Mimiron down we will get him killed next time, good job everyone last night.
