Amirdrassil, the Dream’s Hope

Gnarlroot Awakened Heroic Boss Guide

Last Updated: 7th May, 2024

Raid Setup


Amirdrassil, the Dream's Hope, harbours a guardian like no other - Gnarlroot. Beneath the canopy of trees of green and crimson roses, his presence shatters the tranquil melody of nature. Heroic Gnarlroot may not sing a soothing tune, but he orchestrates a different symphony, one that tests the mettle of champions. His sole mission: to reveal the biggest DK burst in the realms of World of Warcraft.

Fight Style: Single Target fight with frequent add spawns.

Recommended Setup: 2 Tanks / 4 Healers / 14 DPS

Useful utilities: 4x Augmentation Evokers and 1 lucky Unholy DK.

Hero/Lust usage: Intermission when you have the 100% damage buff.

This guide has been updated for Awakened in Season 4 of Dragonflight.

With the item level curve of Season 4 and there not being any affixes means that the fight should be quite similar to when it was first released. Any further updates needed for Awakened tuning will be made as soon as possible.

Controlled Burn Mechanic Icon

Controlled Burn

4 players will get marked with a large circle that inflicts low ticking damage to all players standing inside and will explode after 6 seconds. The explosion will leave a puddle on the ground, but will also activate all Tainted Lasher adds that it hits. Each Controlled Burn target can free every add on one of the sides.

Potent Fertilization Mechanic Icon

Doom Roots Mechanic Icon

Doom Roots

Several roots will spawn in each direction, dealing a medium amount of damage to anyone standing in the spawn swirl. Players need to soak Splintering Charcoal in order to remove the roots.

Splintering Charcoal Mechanic Icon

Splintering Charcoal

Swirls that deal a low amount of damage to the player if soaked, or a low amount of damage to the raid if unsoaked. Players soaking this will gain a debuff called Ember Charred, it inflicts a low amount of damage and it's removed by touching pieces of Doom Roots. 

Each player has 5 stacks from 1 swirl soak.

Uprooted Agony Mechanic Icon

Uprooted Agony

When Doom Roots are removed, the boss takes 100% increased damage for 20 seconds and is immobilised. Afterwards, he gains a 10% damage done buff and the fight repeats from there.


Because Gnarlroot is the first boss, it's traditionally a simple fight. However, there are some aspects of the fight (100% damage buff) that will make this one of the more popular first boss encounters in recent history!

Phase 1 Strategy

Start the fight by having the raid spread around the boss, this will help you with Controlled Burn placement that happens early into the pull. 

Delay using Hero/Lust until the end of the first intermission, which is when you gain the 100% damage buff.

Dodge all the swirls and the frontal and place the 4 Controlled Burn circles on the Inactive Lasher adds. Using the new Ping system to mark the side you want to go is great to avoid confusion. It's not a big issue if you miss some, but it will definitely help healers more in the intermission if you hit all of them!

Once the Lashers become active, they should get picked up by the tanks and placed on top of the boss for extra cleave and AoE damage.

Intermission Strategy

Eventually the boss will start casting Potent Fertilization and will become immune to damage. All inactive adds will become active, so make sure to deal with them first!

Massive roots will spawn around the boss that need to be burned down. To do this, players need to soak the Splintering Charcoal circles and touch the roots afterwards. Once it starts burning, move to the next part of the root until you lose your Ember Charred debuff. Keep doing the Soak and Burn combo until all the roots are gone.

Healers need to pay attention in this phase as there is constant ticking damage on the entire raid, this damage can escalate quickly if some circles are not soaked.

Once all roots are gone, the boss will take 100% increased damage for 20 seconds. Make sure you have all your cooldowns ready and blast the boss when it's taking extra damage.

The boss will do 10% increased damage after each intermission.

After the intermission, the fight so far repeats.

It’s worth mentioning that depending on the tuning of Heroic Gnarlroot’s health, you might need to play through several intermissions. If that is the case, we suggest using Heroism/Bloodlust and cooldowns just after an intermission ends, when the boss takes increased damage, specifically one that is in execute range (under 30% health).
