Belial
DIFFICULTY: TRICKY

Level
Hatred : 80
Terror : 115
Destruction : 120

Location
Act 5 Icy Cellar (Ancients' Way)

Lore
After his defeat in the civil war in Hell, the Lord of Lies and infernal King of Rats was banished to Sanctuary where he plots his return. The icy caves under Harrogath offered him both proximity to the powerful Worldstone and a dark moist breeding ground for his rodent servants.

Strategy
As the Lord of Lies, Belial prefers to cheat in battle. His main offence consists of his Henchmen who use the Punisher spell to poison heroes to death. If one gets through this line of defence, his tiny rat familiars go on the attack. Being so small and fast, they cannot be hit or even aimed at. Belial himself wields a spell that spits out punishers in random directions, as well as an area effect spell that slowly siphons the victim's life away and the ability to summon more rats from the ground to swarm the unwary hero. According to witnesses, Belial does attack recklessly from time to time, chasing his enemy around by teleportation, but demonologists believe that this is just to impress his underlings and his main intention is to get close to summon another batch of Henchmen. Defensively, Belial is protected by a warding spell that makes him invulnerable to all attacks. Occasionally he may drop this shield for a few moments to entice a foolish hero to attack him; this is usually met with a fierce counterattack, but it is the only way to kill him.

Reward
Defeat Belial on Destruction difficulty to get the Book of Lies.

Bull Prince Rodeo
DIFFICULTY: HARD

Level
Hatred : 85
Terror : 115
Destruction : 120

Location
Act 1 Cow Level

Lore
The moolicious heir to the Cow King's throne, Bull Prince Rodeo is out to exact his indiscriminate revenge for all the cattle killed by humans.

Strategy
Rodeo is very aggressive and has a stunning Hoof Stomp and the Blink spell, making it difficult to put some distance between you and him. He can also summon more cows or call upon a Stampeding Herd of exploding cows that ploughs across the screen, trampling all in their path. This ability is unblockable, unresistable and will destroy you if you don't get out of the way in time. But his most common spell, in cooperation with another victim of cruel farming practices, is a wave of chickens that will pursue their victim relentlessly, inflicting devastating hurt with their beaks if they connect. The chickens can be dodged by staying mobile. Being a sacred cow, Rodeo is invulnerable to damage. Warding shields are not an exact science, however, and the spell may occasionally fail, allowing you to hit him with one or more elements until the spell is restored.

Reward
Defeat Bull Prince Rodeo on Destruction difficulty to get the Fool's Gold.

Killing Rodeo does not prevent you from entering the Cow Level again.

Quov Tsin
DIFFICULTY: VERY HARD

Level
Hatred : 90
Terror : 115
Destruction : 120

Location
Act 2 Stony Tomb Level 1

Lore
Hungry for power and misled by Diablo, the Vizjerei mage Quov Tsin almost succeeded in sacrificing the city of Ureh to the forces of Hell. He was defeated at the last moment, but his spirit still roams the burial tombs looking for a mortal vessel to come back to life...

Strategy
As a former Vizjerei in life, Quov Tsin wields the elements. His most devastating attack is a streaming blast of fire, cold and lightning bolts powerful enough to annihilate any hero in a moment. In melee combat, he may use a fire, cold and lightning nova combo that causes massive destruction at close range. Prepare for this battle by equipping resistance items to counter his ability to pierce resistances, and try to find some absorb items to further cut the damage. His contingency spells protect him by teleporting him to safety when struck by any attack. Stay near cover in case he appears too close for comfort. Quov Tsin is protected by a mystical shield that makes him invulnerable to all damage, but thankfully for you, anger is not a good state of mind to maintain a difficult invulnerability spell. It may occasionally fail, leaving him vulnerable to one or more elements. Seize the moment.

Reward
Defeat Quov Tsin on Destruction difficulty to get the Silver Seal of Ureh.

2% chance to drop a trophy on Destruction difficulty. Cube the trophy with the charm for a small bonus.

Astrogha
DIFFICULTY: IMPOSSIBLE

Level
Hatred : 95
Terror : 115
Destruction : 120

Location
Act 1 Mausoleum

Lore
One of Hell's greatest, the scheming spider demon Astrogha has surfaced after the fall of Andariel to continue his reign of terror. He is not the most powerful demon in close combat, but the spider king is never alone.

Strategy
Astrogha does not usually fight his foes directly, but he does not need to. His summoned Spider Statues serve as gateways for his personal swarm, belching waves of crawling Darklings from the depths of the void. Deal with them quickly, but do not touch the statues! They are protected by one of Astrogha's devious tricks: when destroyed, they will both rejuvenate Astrogha and unleash a curse that cripples the assailant causing a swift death. If left alone, they will eventually collapse on their own. Astrogha also possesses a very powerful but close ranged Frozen Orb attack and has warding spells that teleport him away when damaged, courtesy of Quov Tsin's mages. Another dweomer copied from Quov Tsin during centuries of fighting side by side at the head of their respective legions is the warding spell that renders Astrogha immune to all attacks. This is cutting edge magic and therefore still fails from time to time, allowing you to get some hits in.

Reward
Defeat Astrogha on Destruction difficulty to get Astrogha's Venom Stinger.

2% chance to drop a trophy on Destruction difficulty. Cube the trophy with the charm for a small bonus.

Warning! Due to a bug with the way Diablo II handles champions, there is a chance Astrogha may spawn as a boss pack with several copies of himself as minions. When you see a mass of doom spiders, run for your life and restart the game.
