Mimiron Boss Strategy

Phase 1 – Leviathan MKII

This phase is a standard tank and spank fight. Tank the boss in the middle of the room and have your casters and other ranged classes spread out around the  room. Make sure your ranged is at least 15 yards away from the boss, so they don’t eat shock blast. Also, be aware of the mines that will be spawning. Don’t bother disarming them, simply avoid them as most of them will be concentrated between your melee and ranged classes.

Phase 2 – VX-001, Antipersonnel Assault Cannon

The most important thing during this phase is to simply stay spread out. The entire raid should spread out around the room, making sure you have healers equally dispersed. Furthermore, everyone needs to be very aware of the rockets. These rockets will target a section on the ground, so if you see them heading in your general direction simply move 5 yards in any direction to avoid being hit.

Occasionally the boss will begin the laser barrage. If he does start spinning you should move directly behind the boss. This will allow you to avoid taking any damage from the laser.

Phase 3 – Aerial Command Unit

For this phase you will need both a ranged tank and a kiter. As soon as your ranged tank has sufficient threat range can begin attacking the boss until the first assault bot spawns.

Adds spawn at various locations around the room. A spotlight will appear on the spawn location, indicating the type of add that is about to spawn. An orange light means it’s an assault bot and your kiter will need to be picking them up. These assault bots can and should be slowed / immobilized / etc to assist your kiter. Once the kiter has sufficient threat these mobs should be burned down. Make sure you give your kiter sufficient time to build threat.

If the spotlight is green it means a junk bot or bomb bot is about to spawn. Junk bots should be picked up by your tanks. Bomb bots do not need to be tanked, they will walk around a bit and then blow up, simply move away from them and don’t get hit by the explosion.

After the assault bot has been killed he will drop a magnetic core. Use this core underneath the boss. This will pull the boss to the ground, allowing melee to DPS him for a 6 second duration (damage is also increased during this phase).

Repeat the above steps until he’s dead.

Note: turn free for all loot on during this phase to allow cores to be picked up.

Phase 4 – V0-L7R-0N

This phase is essentially all 3 previous phases wrapped into one. There are no new abilities and each phase works exactly the same, however, adds do not spawn during this phase.

Things to look for…

• Ranged tank still must tank the Aerial Command Unit
• Melee tank still must tank Leviathan MKII
• Entire raid must avoid mines
• Melee should run out to avoid shock blast
• Laser Barrage will cast more often, be ready to run behind the boss
• Avoid rockets, move 5 yards in any direction if they are coming towards you

In order to defeat the boss you must kill all 3 sections at the same time, otherwise they will repair. Split your  melee and ranged DPS accordingly, keep heals up, and use the above list to make sure you don’t forget anything…do these things and you’ll have your first kill under your belt
