Here's a concise guide for the Gnomeregan raid in WoW Classic Season of Discovery Phase 2. The Gnomeregan is significantly more challenging than the BFD raid, so understanding the mechanics for most players is crucial for a smoother clear. Now, let's dive right in.

Make sure to have sufficient SOD Gold to assist you when you get into trouble through this dungeon.

Grubbis

The boss at the beginning is called Grubbis. During the boss fight, Grubbis will spawn green gas that gravitates towards the closest player. Then the ads will spawn. Drag the ads into the gas, and the gas will disappear. Moreover, the ads will die. Don’t let the boss get hit by the gas, or he will get a buff. The off-tank should tank the Basilisk as he occasionally drops threat.

This boss is a bit of a DPS race because he starts to spawn a lot more gas clouds, and they pulse AOE damage the longer the fight goes on. I recommend Nature Protection Potions before the pull and maybe reapply one at 30%. Grubbis enrages at 20% health, and he hits really hard, so use a cooldown. You’ll still need to kill his Basilisk when the fight ends.

Vicious Fallout

Clear ads and find a suitable spot where you can tank the boss away from the Desiccated Fallout bindings on the ground. The boss will spawn 3 eradicated Goo that move towards the bindings. The Goo can be CCed, so use slows and stuns. Kill the Goo before they reach the bindings, or they will spawn a Desiccated Fallout. These mobs respawn with 6K health and cast spells at the raid. The boss will also continue to spawn gas clouds underneath him, so make sure you move him out of the gas or your melee will die.

Crowd Pummeler

Throughout this boss fight, Cogwheels will spawn and roam around the map. Don’t get hit by them. He also casts Gnomeregan Smash, which is a frontal that will knock players off the map and one-shot you. Look at what way his feet are pointing, not his hands, and never stand in front of him. At 25%, he will start charging a random player, and this ability will deal lots of damage, so make sure to heal them.

Electrocutioner

Clear out the ads and have the tank pull them against the wall. If you get the Negative Charge, run away from the group. If the tank gets the Negative Charge, just stay against the wall. The boss will cast Chain Lightning on the farthest player away from him, and the 2 closest players will get a debuff. If you get this debuff twice, you will die.

You’ll need to have 2 groups of 3 take turns being the farthest away from the boss. Once you get hit by the debuff, your group should move closer to the boss and have the second group move further away. If a person in the further away group is supposed to be soaking and they get a Negative Charge, send someone else to soak the Chain Lightning in their place.

Managerie

You need to kill all these mobs or they will respawn and keep respawning with 6K health. The Sheep boss cast an AOE Stun, so move away from it and have range DPS this one down. Have the off-tank grab the Dragon boss. The Dragon will occasionally cast a Flame Breath frontal, so don’t get hit by it.

The main tank will tank the Chicken boss and the Squirrel boss. The Squirrel will throw out random group damage, and the Chicken will spawn an egg that your group should DPS down. If your casters are going oom, they can click the red buttons on the pillars and trade health for Mana once every 30 seconds. Remember to kill them all at the same time.

Mekgineer Thermaplugg

Now, let's discuss the final boss - Mekgineer Thermaplugg. This boss has 4 phases:

Fire Phase: Tank him in the open area and run him away when he channels the Flamethrower. If you get hit by the flame, it will stack ramping fire debuffs on you, and you’ll eventually die. These fire stacks do fall off after 15 seconds, so you can have a Hunter pet taunt or the off-tank taunt until the main tank loses his stacks.

When the bombs spawn on you, you need to quickly press the red button underneath the pillar that they’re spawning from. Range DPS with movement are the best for this, but your healers may also want to click because it gives them Mana back. Make sure to kill the bombs before they hit someone so they don’t explode.

Frost Phase: The boss will cast AOE stacks of Frost damage in this phase. The more stacks that you have, the more damage the tank takes from the AOE, and the slower you move. If the bombs explode, they also leave Frost patches on the ground, which gives stacks if you step on it. The frost stacks can be dispelled by a Priest, but you can also pop Free Action Potions on this phase to avoid extra damage.

Poison Phase: Tank him in the middle of the platform underneath the vent. He will channel an AOE damage ability that does not have a castbar, but you do need to kick it or the group will wipe. If the bombs explode, they’ll leave poison on the ground, so make sure to avoid it.

Ultimate Phase: In this phase, he does all the mechanics from the previous 3 phases at the same time. This time he won’t die at 50%, so you need to take him to zero, and then the Goblin will jump out of the mech, and you’ll need to kill him as well.
