Grim Batol Dungeon Guide

Grim Batol is found on the Western edge of Twilight Highlands. Follow the road that leads from Wetlands around the mountain and you will find the entrance to the dungeon.

Here we will give you a full rundown of what you can expect from each of the bosses found here on both Normal and Heroic difficulties as well as the items they drop.

• Bleeding Wound
• Blitz
• Ground Siege
• Frenzy
• Summon Skardyn
• Malignant Trogg
• Modgud's Malice
• Modgud's Malady
• Claw Puncture
• Trogg Dweller
• Claw Puncture

General Umbriss can be a difficult fight that players may often want to skip on heroic difficulty. He will bleed the tank with Bleeding Wound, which requires the player to be healed above 90% health to remmove the debuff. General Umbriss will target the location of a random player and begin to charge there after a short timer, dealing deadly damage to anyone on the path or at the location; quickly move away from the targeted location and be sure not to be in his charge path. He will also frequently target a nearby enemy with Ground Siege, dealing very high Physical damage and stunning anyone in the area.

The main theme of the fight though is the Summon Skardyn ability General Umbriss uses to summon 1 Malignant Trogg and 3 Trogg Dwellers. While the Trogg Dwellers can simply be killed without worry, the Malignant Trogg must not die while near General Umbriss. When the Malignant Trogg dies, it casts Modgud's Malice on all nearby targets; if Modgud's Malice hits a Trogg Dweller, it will turn them into a Malignant Trogg. If Modgud's Malice hits General Umbriss, it will increase his damage done by 100%, stacking each time. Because of this, it's important to either crowd control the Malignant Trogg for the entire fight, or kill it by itself on the side. Do not mindlessly AoE the trolls or you will likely wipe.

Forgemaster Throngus will frequently Mighty Stomp the ground, causing a Cave In on top of a random player. He will also change his fighting style periodically throughout the fight, using Pick Weapon to change his weapon and abilities. When Forgemaster Throngus has Swords equipped he will attack quickly, debuff the tank with Burning Flames stacks, and sometimes Thrash for extra damage.

With the Shield equipped, Forgemaster Throngus will point his shield in a random direction with Personal Phalanx, reducing all incoming damage from that direction by 99% and dealing damage to enemies in front of him with Burning Flames. With the Mace equipped, Forgemaster Throngus should be kited as he will deal 200% increased damage, but move 70% slower. He will jump to a random target, stunning them and dealing damage over 5 seconds. Lastly he will leave Lava Patchs on the ground wherever he walks, dealing Fire damage to anyone who passes through these pools.

• Drahga Shadowburner
• Burning Shadowbolt
• Invocation of Flame
• Invoked Flaming Spirit
• Supernova
• Valiona
• Devouring Flames
• Shredding Swipe
• Seeping Twilight

This fight has two parts, one you will be fighting Drahga Shadowburner, and another you will be fighting Valiona. Invocation of Flame will mark a random place on the ground with fire, summoning a Invoked Flaming Spirit from the spot after 5 seconds, which will fixate on a random player and move towards them rapidly. This Invoked Flaming Spirit must be quickly focused down, using any slows and stuns available to prevent it from reaching and kills its target. When Drahga Shadowburner reaches 25% health, he will run away and mount Valiona, starting the second part of this encounter.

Valiona will frequently use Shredding Swipe, damaging all enemies in front of her. She will also summon damaging Shadow pools with Seeping Twilight on random targets, requiring players to quickly move away from them. The most dangerous ability Valiona has is Devouring Flames, which she will cast in a random direction, severely damaging all enemies in front of her every second. You must be ready to quickly move behind her during this cast or you will likely die.

• Binding Shadows
• Enfeebling Blow
• Feeble Body
• Shadow Gale
• Shield of Nightmares
• Faceless Corruptor
• Umbral Mending
• Siphon Essence
• Twilight Corruption
• Twilight Hatchling
• Twilight Blast

Erudax will launch massive projectiles from Binding Shadows at players, stealing life and rooting enemies hit for 8 seconds. He will also knock the tank back with Feeble Body and increase their damage taken by 200% for 5 seconds; be sure to wait for this debuff to expire before running back in. Periodically throughout the fight Erudax will cast Shadow Gale, covering the entire room in shadow except for a the center of the "storm". Quickly run into the safe spot as the damage from Shadow Gale quickly increases, causing you to die if you stay in it for too long.

When Shadow Gale ends 2 Faceless Corruptors will spawn at the entrance of the room and quickly move towards the nearby Alexstrasza's Eggs, casting Twilight Corruption on the eggs. If this cast completes, the egg will break and hatch 2 Twilight Hatchlings, which will attack random players with Twilight Blast. After breaking a Alexstrasza's Egg, the Faceless Corruptors will then try to heal Erudax with Umbral Mending, restoring 20% of his max health per cast. Use any available slows on the Faceless Corruptors to prevent them from reaching the eggs as quickly while you burn them down as soon as possible; if they do destroy an egg, be sure to interrupt the Umbral Mending to prevent them from full healing the boss. Lastly, Erudax will sometimes buff the Faceless Corruptors with Shield of Nightmares, causing them to deal high AoE Shadow damage to all players whenever they are attacked with the buff active; simply wait this buff out or dispel it before re-engaging them.
