Guide awaiting review
Purchase BlizzCon Virtual Ticket
Knight-Captain Murky is granted to players who attended BlizzCon or purchased the BlizzCon Virtual Ticket. Note that only Horde characters can summon this pet.
Use Queue Dodge and Mrrrgglllrggghl
Run a 2-1-1 ability setup using For the Alliance!, Queue Dodge, and Mrrrgglllrggghl. Open with Dodge before using Mrrrgglllrggghl to negate its self-damage, effectively doubling your value with no downside. A second Murky in the opposing team will frequently mirror your Dodge, extending invulnerability to roughly 4 rounds.
Pair With Multi-Attack Pets
Pairing Knight-Captain Murky with multi-attack pets such as S/S Rabbits, Teroclaw Hatchlings, Bone Serpents, or Li'Bling maximizes the 25% damage bonus his ability provides. Swap Murky out after a full rotation to avoid downtime between ability cooldowns.
Tips
If you face an opponent running Knight-Captain Murky in PvP pet battles, conceding immediately is a recognized strategy given the difficulty of countering the Dodge and clone rotation.
