Grim Batol Layout
General Umbriss + Trash Mobs in the Area
Notable Trash Before General Umbriss
- IMPORTANT: Interrupt Twilight Earthcaller's Mass Tremor cast at all costs. Any spare interrupts should be used for their Earth Bolt cast.
- Sidestep the Twilight Brute's Obsidian Stomp ground visual. He will also strike your tank with Brutal Strike.
- Use defensive if you get targeted by Twilight Destroyer's Twilight Flame DoT effect, avoid their Twilight Ember ground visual and do your best to Line of Sight the Umbral Wind cast.
- Don't pull more than 1Twilight Overseer due to their stackable Rive debuff on your tank. They also have Reckless Tactic aura, which affects every other non-boss-enemy.
Use the trapped drakes to damage the enemies before the General Umbriss boss fight. Even if killed, they will contribute to your % enemy count at the end of the dungeon.
General Umbriss Guide
All Roles
- If you get targeted by Rock Spike cast, position closer to the edge of the room to save space for the follow-up Rumbling Earth ground visual.
- When the boss casts Commanding Roar, look at the indication on the ground and find the save zone to avoid being damaged by the Twilight Drake's Shadowflame Breath.
Tank
- Use your active mitigation when General Umbriss is casting Skullsplitter on you.
Healer
- Top-up players after each cast of Rock Spike.
Forgemaster Throngus + Trash Mobs in the Area
Notable Trash Before Forgemaster Throngus
- Interrupt Twilight Beguiler's Shadowflame Bolt and stop the Sear Mind channel cast.
- Use defensive when Molten Giant casts Molten Wake dealing group-wide damage.
- Sidestep the Twilight Flamerender's Blazing Shadowflame frontal.
Forgemaster Throngus Boss Guide
All Roles

Drahga Shadowburner + Trash Mobs in the Area
Notable Trash Before Drahga Shadowburner
- IMPORTANT: Interrupt Twilight Warlock's Enveloping Shadowflame Curse cast at all costs (alternatively, you can dispel it). Any spare interrupts should go for their Shadowflame Bolt.
- Avoid the Twilight Lavabender's Shadowlava Blast frontal effect. When they cast Ascension, your whole party will take damage from Scorching Heat every few seconds until defeated. This is a high priority target.
- Twilight Enforcer is extremely dangerous for your tank because of its Ramping Rage stackable buff.
Drahga Shadowburner & Valiona Boss Guide
During Phase 1 you will fight Drahga Shadowburner and once he is defeated he will summon Valiona, starting Phase 2.
All Roles
- Interrupt as many Shadowflame Bolts as you can.
- You use Curse removal on the Curse of Entropy debuff.
- When Invocation of Shadowflame is cast, make sure to defeat the Invoked Shadowflame Spirit before he reached its Flaming Fixate target and causes Shadowflame Nova, which is lethal. Here is the perfect place to use your crowd-control abilities.
- Don't stay in any Twilight Wind caused by the Twilight Buffet cast.
- Sidestep the Valiona's Devouring Flame
Tank
- Make sure to help with crowd-controlling each Invocation of Shadowflame and position the boss in a way that enables cleaving on both targets efficiently.
Healer
- Use your healing cooldowns during Valiona's Twilight Buffet as it will deal group-wide damage.
Erudax, the Duke of Below + Trash Mobs in the Area
Notable Trash Before Erudax, the Duke of Below

- Use defensives when Faceless Corruptor is channeling Corrupt on you.
Erudax, the Duke of Below Boss Guide
All Roles
- Use defensives during Void Surge cast and avoid being in contact with Void Tendrils to prevent you from being Depth's Grasped.
- When Shadow Gale is cast, swiftly follow your tank to the safe spot and spread accordingly so you don't get overlapping damage from Abyssal Corruption. If you fail to get within the safe zone before the Shadow Gale cast is finished, you will most likely end up dying.
- Focus the Summon Twilight Hatchlings coming from Void Infusion.
