Instance guide: Seat of the Great Goblin

In the last of the three-person Erebor instances, I’ll be covering Seat of the Great Goblin, part of the Road to Erebor instance cluster that concludes with a six-person instance and three raids when Update 10 releases. For access to this instance, players must either purchase the Riders of Rohan expansion or the standalone Road to Erebor instance cluster in the LOTRO Store.

Seat of the Great Goblin is scalable from level 20 upwards and available on two difficulty tiers. The challenge quest for this instance is available to players at the level cap on tier II. Loot consists of bounties and relics as well as equipment drops starting at level 50 and scaling to the level of the instance.

The instance takes place in Goblin-town in the Misty Mountains and, as one might expect, Seat of the Great Goblin is packed full of all manner of goblins and other foul creatures. There are two main boss encounters in this instance. The first is a troll named Grudom at the bottom of a pit used by the goblins to cast refuse. The second encounter takes place at the throne of the goblin king. Players will face a barrage of enemies and take part in disrupting the succession of the goblin hierarchy.

The Tale of Goblin-town

While goblins may seem a primitive, highly aggressive folk, they still know how to spruce up their home. Like children drawing on the walls with paints, so too have the goblins adorned their walls with images and pictograms that tell a story. The map above shows the location of five hand-drawn murals in Goblin-town; two before the bridge, one on the lower level leading to Gollum’s cave, and two after climbing back up to the upper level. Your reward is a measly 20 Medallions, though this deed is also necessary for the Seat of the Great Goblin meta-deed.


Enemies in Seat of the Great Goblin are plentiful and various. So, too, are the tactics for defeating them.

Goblin-town Lookout – Kill these first. If they are left alive, they will run and aggro mobs you really don’t need to be fighting. Crowd control is your friend here.

Goblin-town Sneak – On tier I, these sneaks use caltrops that give a minor DoT and run speed debuff. On tier II, these goblins can use Eviscerate, a major DoT only curable out of combat. Kill these quickly, preferably before they land any attacks.

Goblin-town Archer – Ranged enemy; on tier II, can debuff incoming damage, giving players +15% incoming melee/ranged damage

Goblin-town Boggart – Come with four allies attached that use a stackable DoT

Goblin-town Sapper – At 75% morale, becomes Volatile! – if alive after 12 seconds, the Sapper dies and leaves behind a DoT hotspot

Goblin-town Warrior – Vicious Leadership aura gives nearby allies +10% movement speed.

Goblin-town Wound-tender – Might in Numbers aura gives nearby allies -10% incoming melee/ranged damage; can also heal allies; has brittle armour, making it vulnerable to melee damage; on tier II, can apply an incoming healing debuff to players

Trained Warg – Uses Debilitating Bite debuffing player run speed, attack duration and skill inductions.

Cave Bat – Can disarm (disable primary weapon) and silence (disable song skills)

Part one

Hack-n-slash is the name of the game as you enter the lair of the goblins; there are plenty of enemies here to sharpen your blades on. Use the list of mobs above and pass swimmingly into the main throne room.

Exit the long path to a fork in the road, one road leading straight and guarded by many goblins, and two roads leading left and right both up ramps. There’s a mural on the central path, and the right path is a dead end until you reach the final boss, so take left path. Take out the lookout, deal with a few more mobs pulls you’ll soon find yourself crossing a bridge to the great goblin’s throne.

By the way, the second to last group of mobs is avoidable if you jump off the path instead of running through them. Just watch out for the lookout in the next group that will try to aggro the group you just skipped.

Before you make it across the bridge, Uloga, the Great Goblin, intercepts your fellowship, and let’s just say that your immediate future looks rather shaky. Uloga talks for a while, posturing mightily while his kingdom crumbles around him, and then orders a sapper to blow the bridge. If you’ve done this before, as soon as you activate Uloga’s drama you can drop off the bridge and into the refuse pit below where the first boss awaits.

Boss 1 – Grudom

Grudom (Seat of the Great Goblin)

After falling into the garbage pit, you’ll encounter a gaunt-looking troll named Grudom scavenging through rubbish. Before you fight him, you must take on other goblins who were thrown into the pit. These emaciated malcontents come in five groups of two, one archer and one warrior. They’re on a timer, so if your DPS isn’t great enough, you may be fighting all ten at once. It’s important that the tank grabs and maintains aggro on all incoming mobs otherwise your healer might die and you’ll have to do without during the fight with Grudom.

Immediately after defeating these 10 emaciated goblins, Grudom attacks. One of the major things to watch out for is the falling debris from the upper levels. Where they will land is marked on the ground by a glowing orange circle just like the boulders in Iorbar’s Peak. Getting hit will take a significant chunk out of your morale, but if you position Grudom in the path of falling debris, he’ll receive a 10-second debuff giving him +50% to incoming damage.

In addition to random falling debris, Grudom has three scripted events at 75, 50 and 25% of his maximum morale. He’ll run to the middle on a mound of garbage, go into a rampage and cause more trash to fall to the ground. Standing near Grudom will cause damage through the duration of his rampage.

One way to deal with this is to have everyone run to where there are no trash circles. This is difficult because the circles don’t all appear at the same time and lag can cause you to think you’ve cleared a circle, but the server still thinks you’re inside. On tier I, less trash will fall making it easy to avoid, but more trash will fall on tier II, giving you less opportunity to escape unscathed.

Another way is to have everyone stand within one circle, take the damage, then heal up afterward. And yet a third way would be for everyone to stand where Grudom is and heal through the damage from his rampage.

Also watch out for Grudom’s Filth-fed skill which gives him a melee damage buff. On tier I, this skill is interruptable and gives him +20% melee damage, but on tier II, it is not interruptable, gives him +30% melee damage and also drops an Acid DoT hotspot for several seconds.

Part two

After defeating Grudom, the gates open so you can catalog the third mural guarded by a few goblins in the north and continue out of the trash pit through the east gate. Halfway through this corridor, you’ll be ambushed by a number of goblins. Defeat those and the next group of goblins guarding the rope leading back upward.

On the upper level, defeat the next group of goblins, crowd control and kill the Goblin-town lookout (unless you’re looking for a fight) then defeat one more group of goblins. As you find yourself at the foot of the throne, you’ll see a handful of Goblin Lickspittles, numerous, but easily defeated. Defeat all ten of these then approach Uloga atop the Seat of the Great Goblin.

Boss 2 – Uloga, Mârubh, and Brosh

Goblin-town (5)

This encounter is three bosses in one, oh and a heck of a lot of goblins. By my count, it’s three bosses, six wargs and twenty of those little Lickspittles; they’re more of a nuisance than anything. On tier II, the challenge quest requires you to defeat all three of the bosses within four minutes, a hefty challenge. If you find your group lacking DPS, consider refining your skill rotation to include more DPS and less healing or even swapping out a main healer with an off-healer like a Captain or Lore-master for a little extra firepower.


Uloga is the current and no so popular goblin king. After you engage him and start his drama sequence, him and his two guards attack. Uloga is immune to damage while his guards are alive, so take out the guards first. And because he is immune, Uloga may lock aggro on to a healer. If this happens, have the healer kite Uloga in an open space away from the throne. Kill the guards, then kill Uloga quickly and Mârubh will rush in to usurp the throne.


Mârubh’s most deadly attack is the Spreading Miasma, a contagious DoT that spreads to your fellows if you’re too close to them. If you’re ranged, stay away from everyone else, but if you’re melee, keep an eye on your debuffs and be ready to run if you get the uncurable disease.

Mârubh will also call those 20 Lickspittles, five at a time. Take them out easily with AoE and they won’t be much trouble. The second goblin king should go down nice and easy then Brosh is ready to make a play for the throne.


The first thing to watch out for is Brosh’s Deep Cut, a constant DoT similar to the Eviscerate skill used by Goblin-town Sneaks on tier II. Brosh will also summon wargs to defend him, two at a time. Continue to focus attacks on Brosh, but use AoE skills to take out the wargs.

Brosh is also furious; he gains a stacking buff about every 12 seconds that gives him +5% melee damage as well as +5% incoming melee and ranged damage (sorry tactical users). This buff stacks to 10 but if you’re doing the challenge, you probably don’t have time to wait that long.

Differences on tier II

  • Goblin-town Sneaks can use Eviscerate, a high damage over time, uncurable debuff that only wears off out of combat.
  • Goblin-town Archers can use Pierced Armour, +15% incoming melee/ranged damage.
  • Goblin-town Wound-takers can use Open Wounds, -40% incoming healing.
  • Grudom – Filth-fed skill is no longer interruptable and drops an Acid DoT cloud where he stands


See this post or this spreadsheet for level 85 values of equipment loot. Equipment loot can drop starting at level 50 and scales accordingly and only drops from the final chest and challenge chest. Rare (purple), incomparable (teal) and epic (gold) loot can drop from the final chest and epic loot can drop from the challenge chest. Loot has a higher chance of dropping on tier II.

To give you an idea of the currency rewards, at level 85 on tier I, I received 193 Marks and 30 Medallions for completing the instance.
