  • The player starts with Ashes of OutlandKarnuk, Outcast.
  • At Start of Game Ashes of OutlandShalja, Outcast and Ashes of OutlandSklibb, Outcast are shuffled into the player's deck.
  • At the boss' first turn Ashes of OutlandEntombed in Rust is automatically cast, shuffling Karnuk, Outcast to the last 2-5 cards of Baltharak's deck.
  • When Karnuk, Outcast is drawn, it is summoned to the right-most position of the player instead of putting into Baltharak's hand.
  • If Karnuk, Outcast is drawn when the player has 7 minions on a board, the right-most minion of the player will be destroyed and Karnuk, Outcast will place this position.
  • Ashes of OutlandInfectious Sporeling becomes the highest priority target of Baltharak after being played.
  • Karnuk, Outcast becomes the highest priority target of Baltharak after being summoned. If it's on a board with Infectious Sporeling at the same time, enemy will destroy Infectious Sporeling firstly.
  • Killing Baltharak before Ashes of OutlandKarnuk, Outcast is gone from his deck, or if Karnuk was milled or killed, is allowed and will not affect future events.


This is a battle of endurance. With a good variety of Demons and even a Hero Power that grants a HUGE source of healing and card draw when a Demon dies, Baltharak is no slouch as the final boss of Chapter 1. Due to the immense healing granted by his Hero Power, rushing Baltharak would be almost impossible. However, this powerful ability can be proven to become his own undoing.

Your only focus here should be on survival, maintaining good board control, and picking up the most efficient trades possible with your minions. NaxxramasDancing Swords in particular is great for its good stats and additional card draw for the boss. When his hand is full, use LegacyColdlight Oracle at any given opportunity to mill out more minions from his deck.

Slowly but surely, it'll reach to the point where you've killed every minion Baltharak could play, leaving him to take huge fatigue damage resulting from the increased card draw.


Before match

Illidan Stormrage
Our heroes brace and find their nerve: Before another's made to serve.


Aranna Starseeker
Another one of those Rusted fiends... get back!
This orc is ours! But we'll take you too...

Emote Response

Was that a joke? I think it was a joke.


All is rust.
Good things come to those who wait, don't they? Heheh.
The Mag'har orcs are destined to serve the Rusted Legion.

Turn 1

Karnuk, Outcast
My people in this land reside... We're drowning in a rusted tide!

Boss cards

Ashes of OutlandEntombed in Rust
Ahhh... What a refreshing soul.
Ashes of OutlandUnstable Felbolt

Ashes of OutlandImprisoned Scrap Imp
Get out here already, imp!
Ashes of OutlandEnhanced Dreadlord
Go on then. Destroy them.

Player's cards

Ashes of OutlandInfectious Sporeling
Ugh. Yuck. Sporelings are so... slimy.
Ashes of OutlandSklibb, Outcast
Another one of those mushroom things... a tasty snack.

Karnuk, Outcast is summoned on the player's board

Aranna Starseeker
Awaken priest, rise up: We're here! We'll fight these rusted puppeteers.
Karnuk, Outcast
I will join you; we will hold fast! Together forever, we outcasts.


Karnuk, Outcast
Thank you. This one has hunted me for weeks.
Aranna Starseeker
You don't seem like the other orcs here... who are you?
Karnuk, Outcast
I am Karnuk. I refused to join these Rusted fools and for that, they hunt me.


Baltharak is original to Hearthstone. He is a nathrezim.

Wowpedia icon.pngThis section uses content from Wowpedia.
Nathrezim are intelligent and cunning demons who usually act as intelligence agents, interrogators and emissaries for the fiery lords of the Burning Legion, notably Kil'jaeden, as well as tacticians and lieutenants upon the field of battle in times of war. While they are powerful foes on the battlefield, they prefer to turn nations against each other through manipulation and guile. The nathrezim are merciless villains who feed upon the energies of mortal creatures. They utilize terror and subterfuge - often turning brother against brother as whole worlds fall before their dark influence. They are known to be extremely manipulative and masters of trickery; they sometimes refer to themselves as thal'kituun in their language, meaning "the unseen guests".
Their homeworld, Nathreza, found a similar fate to Draenor, as Cosmetics - PNG logo.pngIllidan Stormrage obliterated a great part of it. The demon hunter believed that he caused a cataclysmic explosion by overloading the portal he had opened to Nathreza.
During the Third War, some dreadlords served as the Lich King's jailors, at the behest of Kil'jaeden, and commanded the Plague of Undeath and the Scourge that swept through Lordaeron.


  • Baltharak's idle quote, "All is rust", is a reference to Warhammer 40,000. The Traitor Space Marine Legion, the Thousand Sons, are noted for their battlecry of "All is Dust".
