Doesn't work. I've tried at least 15-18 times (lost count), and there are five RNG points that have to line up. This is probably the best pet combo and strategy available, but Blizz just put pets in that are OP due to stuns. No fault to the author here. I'm just not willing to burn up 100 pet bandages and my entire afternoon waiting for the RNG gods to line up just right.
Turn 1 ToA
Turn 2 PB
Turn 3 Corrupted Blood
Turn 4 PB
Turn 5 ToA (Chum dead)
T6 PB (If you can) take stun (hopefully)
HP Blighthawk in
T8 Slicing (until 1 round before bash)
T11 Lift Off
T12 (You dodge) LO hits (Bruce dead)
T13Slicing Wind until your Blighthawk dies.
HS Blightbreath (MUST BE HS)
T14/15 Follow as above.
My Blightbreath is B/B and the problem with that breed is speed (260) is the same as Maws Jr, so it's random whether you go first, which matters for Bash. I'd say it's still possible if Slicing Winds gets max hits in, and/or you get lucky and go first when you Bash, but it might take several tries...
