Heroic Omnotron Tips

So this Heroic fight is really easy in terms of healing and DPS requirements, but you need to learn all the mechanics. It’s one of those “do a mechanic wrong and you die” fights. Unforgiving. However, if you do everything right it’s kind of a joke. Our first kill was about 8 minutes long, so expect to go through each tron rotation a couple times. I don’t have many tank specific tips, but I’ll go over our strategy and composition first.

Tanks – Protection Warrior (Myself), Protection Paladin

Healers – Restoration Druid , Holy Paladin, Discipline Priest

DPS – Moonkin, Fire Mage, Assassination Rogue, Destruction Warlock, Frost Death Knight

The Death Knight was Frost for the interrupts. I think his DPS was like 8k overall, with the Warlock around 20k, the Mage around 30k (spell stealing the Arcano buff), tanks around 8k, Boomkin around 15k, and Rogue around 10k. So I repeat, not a DPS race.

Aside from the normal mode mechanics, Nefarian enters this Heroic mode like every other. Here Nef chooses to empower 1 ability from the two active trons. This means that when you pull, the first “empowerable” ability that happens will be empowered as only 1 tron is active.

The abilities are as follows,

Magmatron – Encasing Shadows on the target on Flamethrower, rooting him/her to the ground.

Arcanotron – Pool explosion. The Power Generator will grow larger and explode after a few seconds, pretty much 1 shotting anyone caught in it.

Electron – Shadow infuses the Lightning Conductor after a few seconds. This person now pulses Shadow damage to the entire raid, dealing more damage the further away you are.

Toxitron – A mass death grip/poison pull/whatever you want to call it. Nefarian pulls the entire raid into the Toxitron’s green poison cloud.

And that’s it besides more base damage on their abilities and more health in total. The only strategies you need to devise are how to deal with each new mechanic. We found it easiest to stack the entire ranged group at one point, even when Electron was active. Stacking makes every new mechanic a lot easier to deal with and we could just heal through the chain lightning damage.

So when each ability came, we did the following.

Empowered Magmatron: Stack together, spread from the acquired target, then restack.

Empowered Arcanotron: Stack in puddle, then run out and restack.

Empowered Electron: Sidestep from group for 3 seconds, then sidestep back to the stack.

Empowered Toxitron: Stack far from Toxitron. After poison pull, run away and restack.

Toxitron proved to be the most difficult to deal with (the reason why many guilds killed this encounter the first time when Fixate was bugged, making the adds that spawn not even target players). We decided that tanking him against a wall with the entire raid at half max range made it the easiest. This means the cloud generally went on the raid there, and they could move back to max range after. If a pull happened, then the group would move back to max range again. The adds always had to go through the cloud to reach the group as well, which made them easier to kill. This picture tries to help explain. The BAD red circle is the poison cloud. Skull is Toxitron. “X” is the other active tron.

Other trons didn’t require specific positioning for us.

Having poison adds killed quickly, a cool down rotation for Magmatron’s Incineration Security Measures, having the raid use self cool downs to entirely or partially negate Flamethrower, interrupting all Arcane Annihilators, not attacking shields, etc. all apply from normal mode.

However, do not move trons into the poison cloud. The risk of causing a wipe by doing this is too high compared to the small DPS reward you get. Maybe later when you’re more comfortable with the encounter, but I wouldn’t recommend it when learning.

Specifically regarding the interrupts on Arcanotron. Having a Shaman is obviously the best way still. If not, have 2 players swap back and forth. Note that if a poison pull happens (ie Arcano and Toxic are both active), you’ll need a ranged interrupt to cover his cast.

Alright enough of that. This is a tanking blog. Here’s the cool stuff I did,

1. I always wanted to be tanking Toxitron due to speccing for Piercing Howl. If you have a reliable slow, then you can ignore this, but we needed a slow. To ensure I always tanked Toxitron we did the following. If he was first up, I started tanking. If not, our Paladin did. If Toxitron was second active (or fourth), then we didn’t need to swap. If he was third, I’d grab him as he came active and the Paladin would taunt my tron. This made the transition smooth. Apply this method if you want to always tank a specific tron (maybe Arcano for interrupts).

2. If a poison pull happens, use Charge as soon as you can to basically avoid that mechanic. Consider popping a cool down as well, since direct healer will stop for about 3-4 seconds.

3. Wear Mirror of Broken Images and use it on Shadow Conductors or Incineration Security Measures. As many times as you can when one of these abilities is active. You generally won’t be stacking when a Shadow Conductor happens (unless Electron is active first).

4. Prepot armor if you’re tanking first, otherwise I waited for a point when I needed healing and used a health potion at the same time as my health stone. After a poison pull late in the fight is generally a good time.

Spec I used: Piercing Howl spec.

Gear differences: Just trinkets. Used Mirror over Vial.
