Hearthstone Blackrock Depths Deck Builds, Boss Strategy Guide

By   /   Apr 14, 2015

The Blackrock Mountain singleplayer campaign mode for Hearthstone is split into various ‘wings’ or stages. Each Wing will have its own set of unique bosses that will challenge you with their powerful decks, and in order to complete the wing and progress, you will need to take these bosses out.

Hero Power

Normal: Pile On! – Autocast that costs 0 mana and puts a minion from each deck into the battlefield.
Heroic: Pile On! – Autocast that costs 0 mana and puts two minions from Coren’s deck and one from yours.

Boss Strategy
When playing Coren on Normal mode, it is fairly easy to beat him even with basic cards. You will however need to put lots of big minions into your deck. You should have around 18-20 minions in your deck when fighting Coren, and the remaining cards should be control spells or simple damage cards. Coren’s Hero Power should be negated with so many minions and he’ll go down easily.

In Heroic mode, things are a lot more complicated. Coren in Heroic mode is probably the most difficult boss in the Blackrock Depths because of his powered up Hero Ability in this mode. He’ll have that extra advantage in numbers and can quickly overwhelm you.

The key element in defeating Coren is to have decks with 5 or 6 Legendary minion cards that can take use of his Heroic Power. Have powerful, big minions that do not have any Battlecry and then support them with the best spells you got.

A Preist Deck with all legendary minions works brilliantly against Coren in Heroic mode.

The most important factor though in Heroic difficulty are the first few turns. If the starting turns are not going in your favor, it is better to concede and attempt again, as the first 3-4 turns are the key in navigating towards a victory against Coren.

Hero Power
Normal: Jeering Crowd – Summon a 1/1 Dark Iron Spectator. Costs 1 mana.
Heroic: Jeering Crowd – Summon a 1/1 Dark Iron Spectator (auto-cast). Costs 0 mana.

Boss Strategy
A first look at Grimstone’s deck will send shivers down your spine. All legendaries? Yikes! Don’t worry though – Grimstone isn’t as intimidating as the quality of his deck. There are no spells in his deck and only a limited number of minions.

Also, he hardly has any taunting option apart from his Iron Spectator from the Hero Power.

The optimum way to deal with Grimstone is to build an aggressive basic deck that can easily overwhelm his fairly early on. Classes like Druid, Rogue, and Mage work splendidly well, and should be able to take care of Grimstone’s Hero Power in Normal Mode as well.

Use around 16 or so Minions in your deck to overwhelm Grimmy boy quickly, then unleash terror with powerful controlling and damage spells, and he should go down quite easily in Normal mode.

In Heroic mode, Grimstone is a little tougher, but he’s still not as challenging as Coren in this difficulty. Grimstone will start off with 4 Mana crystals, which means that you won’t have the privilege of starting off dominantly.

For this, you’ll need a minion-heavy deck (once again, Druid, Mage, and Rogue decks work the best against this boss).

Overwhelm him with your minions and AoE spells until Grimstone has nothing left to offer. After that, simply just finish him off. You shouldn’t even be needing Legendary cards for this. Just a few Rares and one odd Epic would be sufficient.

Heroic Power
Normal: Power of the Firelord – Costs 2 mana and deals 30(!) damage. Thaurissan cannot however use this ability as long as his wife Moira is on the battlefield. Moira is a 1/3 NPC who never attacks minion unless they taunt her.

Heroic: Power of the Firelord – Costs 2 mana and deals 30 damage. Thaurissan cannot however use this ability as long as his wife Moira is on the battlefield. Moira is a 3/1 NPC in Heroic mode who never attacks minion unless they taunt her.

Boss Strategy
Thaurissan’s Heroic Power is powerful enough to wipe you out with a single hit, unless you can somehow survive the 30 damage with some armor. If you can, you will actually have a huge advantage, but we’ll assume that you can’t, and work a strategy with that.

Thankfully, Thaurissan will not use this ability as long as his wife minion Moira is present on the board. This is why you absolutely have to make sure that she stays alive throughout the game.

The number one factor that can completely spoil this for you is the pack of Unstable Ghouls in both difficulties.

Unstable Ghouls will deal damage to all minions, and in Heroic difficulty Moira only has 1 health, which means when the Unstable Ghoul attacks, she will die, and the next turn Power of the Firelord will be initiated. Taking out these ghouls should be an absolute priority for you.

You should also avoid AoE spells and opt for a deck that utilizes target-specific spells and controlling cards. It is also important to know that Moira may not attack your minions, but she will attack you, so it is important that you take this into consideration and pace your game accordingly.

In Normal mode, an aggressive Mage deck with a decent set of minions is more than enough to outpace Thaurissan and finish him off.

Use basic cards and bring along around 16 or 18 minions with you. Use these minions along with freeze-based attacks to gain pace and outmaneuver Thaurissan, and you should be able to defeat him.

In Heroic mode, being aggressive is not an option. Moira is more fragile, but will deal 3 damage to you.

You will have to deal 45 damage to Thaurissan to kill him. This means that right from the beginning you are automatically in a disadvantage, since your health will be chipped away by Moira (while you won’t be able to deal with her) on a very regular basis.

For this very reason, the Priest and Warrior classes that can either heal or armor up are absolutely necessary to negate the disadvantage. Use powerful minions like Shade of Naxxramas to give you additional advantage at later stages of the game.

Take out the Unstable Ghouls as quickly as possible to prevent an abrupt end to your game.

At one point, Thaurissan will use his Death’s Bite card. This card will deal 1 damage to all minions, meaning it will also kill Moira, and the next turn will allow Thaurissan to use his Hero Power, effectively winning the game.

You have to make sure that Thaurissan is near his death when he actually draws this card. This is going to be a tough battle that may take several tries in Heroic mode in order to get accustomed to the Death’s Bite draw and Moira’s impactful damage.

With a good mid-budget Priest/Warrior deck with a few Rares and one odd Epic, you should be able to defeat Thaurissan once you get accustomed to his tactics in Heroic mode.
