The fifth week of the “Blackrock” expansion of Hearthstone has begun, and the last wing is now opening. This time, it goes into the “Secret Laboratory” to defeat the last four opponents that Nefarian can throw at the adventurers – including himself (once again). In terms of story, the Secret Laboratory corresponds to the “Blackwing Descent” from World of Warcraft, which is why the mechanics of the bosses are also heavily based on their MMORPG counterparts.
Final Stretch: 4 bosses that require solid planning

First, you face the Omnotron Defense System. As in WoW, the 4 colleagues are activated in different sequences and have different effects on the battlefield. Arcanotron grants both players +2 spell damage, while Toxitron deals 1 damage point to all other minions every turn.
Next, you need to defeat Maloriak, the head alchemist of Blackrock. His passive ability ensures that all minions start with swapped health and damage values, turning harmless 1/7 tanks into serious threats. The penultimate opponent is the blind dragon Atramedes, who grew stronger in the raid the louder the players were – in Hearthstone, this means that each card played improves the dragon’s weapon. One or two “Acidic Sludge” could be useful…
The final boss is, of course, Nefarian himself, who dominates the battlefield with a whole lot of his own cards. Especially in heroic mode, you can expect many attempts if you want to put the lord of Blackrock in his place.
New Cards: The Highlights at the End
Truly effective dragon decks will probably only emerge from this week. For the finale, Blizzard has saved four dragons, which you will see more frequently now.
- The “Vulcan Dragon” becomes cheaper for each minion that has died this turn. If you have cleared the board effectively, you might be able to play the 6/4 monster for free.
- The “Drakonid Crusher” is quite solid with its 6/6 for 6 mana, but becomes a true monster with an additional +3/+3 if the opponent has less than 15 HP.
- Buffable classes like Priest, Druid, and Paladin will benefit from the “Dragoncaster“, which has stats of 3/5 for 4 mana and gains +1/+1 each time the owner casts a spell on it – including all “Spare Parts” from the previous expansion.
- The “Corruptor of Blackwing” is not a dragon, but benefits if you have one in hand. Its battle cry ensures that the 5/4 creature deals three damage to a target of your choice for 5 mana.
- As a legendary card, there is the black dragon “Nefarian“, which costs 9 mana in line with the other great dragons and has a respectable 8/8. Additionally, it gives the player two random spells from the opponent’s class. Finally, you can get back at the priests for their mind control!
Finally, paladins receive their class challenge and thus the card “Devout Watcher“, which allows the owner to draw 2 cards for 5 mana. Each minion killed in that turn reduces the cost by 1, which can quickly lead to free card drawing with the many recruits of the Silver Hand.
Do you already have great deck ideas in mind? What card combinations do you find particularly interesting? And most importantly: How did you enjoy the adventure?
