Darkheart Thicket

Dungeon GuideRetail

Boss abilities and loot tables from Blizzard's own journal, boss by boss.

In the shadow of Shaladrassil, the Nightmare permeates every inch of the once-lush forest. Where the eldest and greatest druids once tended to the woods, meditating beneath the great world tree, corruption and madness now reign. Deep within the tangled thicket, the Nightmare Lord Xavius works to break the will of his greatest prize.

Written notes for this instance are a later milestone. Everything on this page comes from Blizzard's journal data.

Bosses

1. Archdruid Glaidalis

Glaidalis was once known as among the most talented shapeshifters in all of Azeroth, and the elders of Moonglade would regularly send their most promising disciples to his care for instruction. But as has sadly too often been the case, those who are closest to nature are often the first to fall into the Nightmare's clutches.

Abilities

Overview
Archdruid Glaidalis is a master shapeshifter, transforming into bear and cat forms with ease as he calls down corrupted starshards to bombard his foes.
Nightfall
Crawls towards its prey, leaving a trail of corruption in its wake.
Primal Rampage
Grievous Leap

Loot

2. Oakheart

An ancient who formed from an offshoot of Shaladrassil itself, Oakheart has survived the Sundering, the Cataclysm, and countless blights. The ancient was able to weather these storms by drawing strength from the essence of the Dream itself. But now, that wellspring has become his undoing.

Abilities

Overview
Oakheart is a devastating brute that pummels the players with powerful physical attacks and [Nightmare Breath]. Beware the [Strangling Roots] erupting from the ground during the fight.

Loot

3. Dresaron

Once a young green drake, tending to whelps in the shadow of the great world tree, Dresaron is now engulfed in nightmare, lost in a fog of hatred and fear. He lashes out with powerful wings and a withering breath, unleashing his rage on any who stumble into his clutches.

Abilities

Overview
Dresaron engages the players amidst of a clutch of corrupted dragon eggs. Occasionally during the fight Dresaron will use [Down Draft] to push the players back into the eggs, spawning whelplings.

4. Shade of Xavius

Once a powerful mage, and a councilor to Queen Azshara, Xavius forged a pact with Sargeras to enable the Legion's first invasion of Azeroth. Cursed and tormented in the wake of that defeat, Xavius now projects his true power from the Nightmare into our world, focusing his dark might to break the spirit of his old rival, Malfurion.

Abilities

Overview
The Shade of Xavius, a shadowy reflection of Xavius's true power, sits in the hollowed-out core of Shaladrassil tormenting Malfurion. At 50% health, the Shade of Xavius casts [Apocalyptic Nightmare] in an attempt to burn Shaladrassil down around him.
