Gruul the Dragonkiller

Boss Overview

Gruul the Dragonkill starts with 50 Health and utilises a Warrior-style deck built around exploiting damaged enemies, with cards like Execute and Frothing Berserker. The boss will use its Shatter Hero Power immediately at the start of each turn do deal damage randomly split across your board.


Deck-Building Advice

The boss's Shatter Hero Power is both a blessing and a curse. While it can efficiently chip away at your board, you can also use it to activate many cards of your own like Frothing Berserker, Battle Rage, Rampage, and Bloodsworn Mercenary.


Gameplay Strategies

In the early game, it can be difficult to keep any minions on the board due to Shatter. However, it should be noted that the Hero Power can also go face, potentially missing your minions. With this in mind, it is often better to play passively early on and then develop a strong board in the mid game. Once you are able to develop a board, the Shatter Hero Power loses a lot of value as it cannot consistently kill your minions and will simply waste the boss's Mana. If you are using minions that benefit from taking damage, this is the ideal time to play them to start pushing damage.
