For the minion of the same name, see Xavius.

Xavius is a boss encounter in Demon Hunter Prologue adventure. It is the second encounter of prologue.

The boss for this encounter is Xavius, while the hero the player controls is Illidan Stormrage. However, the player does not have to battle with Xavius, but the Unstable Energies summoned at the end of turn from the Demonic Portal.

Either killing Xavius or 30 Unstable Energies wins this encounter.

Special rules and triggers

  • At the start of each turn, 1-3 random Unstable Energies are spawned on the side of player that ended turn. Dark Unstable Energy are the most common.
  • All minions switch sides each turn, so the active player will always be in control of any minion played as well as the Portal, and their opponent will always be in control of the Unstable Energies.
  • The player who isn't active is Immune for the turn. This Immunity drops briefly at the end of the turn to allow Fiery Unstable Energy to deal damage to both players.
  • Xavius never uses his hero power.

Known bugs

  • Destroying 30 Unstable Energies isn't necessary. Killing Xavius via Fiery Unstable Energy also counts as win. This appears to be a mistake, since the dialogue at the end of the fight is unchanged.

Before match

Illidan Stormrage (present)
As a mage, I relied on the Well of Eternity, controlled by Queen Azshara herself. I learned that she was behind the demons' invasion, condemning us all. And for what? Power. Irresistible power... There was only one answer.


Why have you come to the palace, rebel?
Illidan Stormrage
I wish to join your side.
Prove yourself in combat, and I shall consider it.

Emote response

Such cleverness! How unexpected.


I am the High Councilor. It is my job to control entrance to the palace.
If it weren't for this trouble with portals, the whole world would be conquered already.
The master spoke to me first. ME! Not you.

Turn 1

I will grant you demon claws. Use them well. (Illidan's hero power changes to Demon Claws)

Boss' turn 1

Our portal is fragile. Strengthen it and earn the master's favor.

Boss' turn 2

Why abandon the resistance?
Illidan Stormrage
You control the Well. Without it, I am nothing.

Boss' turn 3

You would betray your own brother?
Illidan Stormrage
My beloved prefers him. So, yes.

Boss' turn 4

Illidan Stormrage
I hope your master is watching.
Fear not. He is very close.

Boss' turn 5

I used to be an elf like you. The master gave me many gifts.

Casts spell on turn 7-8

For the glory of Queen Azshara!
Obedience before all.
Serve the master.

Destroying the Unstable Energies

7 Unstable Energies are destroyed
Empower the portal...
14 Unstable Energies are destroyed


You have passed. Prepare to receive your just reward from the master.
Illidan Stormrage
No, no, just your acceptance is reward enough!
You... are... the... one.
Illidan becomes the Demon Hunter
Illidan Stormrage
My eyes! Yet... such things I can see now!


Lord Xavius was one of the Highborne's most powerful sorcerers and the high councilor to Queen Azshara during the time of the War of the Ancients. Since Azshara concealed her magical prowess, Xavius was considered the most powerful Highborne to whom the rest measured their skills. He was later transformed into the first satyr by Sargeras, before ultimately being transformed into the dreaded Nightmare Lord.
