Iron Juggernaut is the 6th fight in SoO and is as close to a tank & spank as we’re going to get. Though he looks menacing, it’s actually one of the easier fights. Heroic mode is almost exactly the same for a ranged dps.
Iron Juggernaut is broken up into two phases. Assault phase come first and lasts 2 minutes. During this time he smacks the tanks around, casts Borer Drills (look like spikes coming out of the ground) that you should move away from, and fires Mortar Cannons which requires everyone to be spread out 8 yards apart. He also does some unavoidable damage on the raid. The most troublesome ability in Assault phase is Crawler Mines. These will spawn around the boss and will explode, doing massive damage to everyone, if they are allowed to detonate. To prevent them from detonating, they must be stomped on. Generally, whichever tank does not currently have the boss is the best option for stomping mines. However, if they can’t get to all of them another raider, with a good damage mitigation cooldown, will need to pick up the extra(s).
Heroic only – A sawblade will be launched from the boss, and then return, doing damage to anything it hits.
The second part of the fight is a 60 second Siege mode. During this phase, the boss does not need to be tanked. Raid damage goes up in this phase immensely, and keeping yourself alive becomes much more important than damaging the boss. There is unavoidable raid-wide damage and the boss fires avoidable Demolisher Cannons. You can tell where these will land as there will be a big, red, circle. Three times during the phase, the boss will cast Shock Pulse, doing massive damage and knocking everyone back – it’s important to put your back to a wall so you don’t get knocked out of range of healers. Explosive Tar will be spread around on the ground and people will randomly be targeted by a Cutter Laser, which follows them around for a time. Do not kite the cutter laser over the tar or it will explode and probably kill most of the raid.
Heroic only – The boss is extra dangerous to the melee in this phase due to Mortar Barrage.
Level 15 – Crouching Tiger, Hidden Chimera
Deterrence owns on this fight, and you’ll want to be able to use it a lot. Deterrence is also pretty good if you get caught off guard and get knocked back. Glyph of Deterrence is a good option as well.
Level 90 – Glaive Toss
Tips for the Fight
- Deterrence is amazing on this fight. It will let you stomp on mines without dying. In Siege phase deterrence will completely deflect the raid-wide Seismic Activity damage and the Shock Pulse (both the damage and the knock-back).
- If you do get knocked back too far, Disengage can help you get back faster. Or use it to get out of the Demolisher Cannon damage zones.
- Use your big cooldowns during Assault phase.
- Use your Healthstones! You obviously can’t Deterrence every Shock Pulse, so use a Healthstone after one of them.
