Bo Bobble

Stay on top (literally) of Bo Bobble the entire time and Max's rockets will do most of the damage for you. Just move away from Bo then back on top of him each time a rocket comes, or every other rocket, and it's a one shot. When Bo runs into the shield, kill the generator, or let the rockets kill it for you... either way, just stand on top of Bo and it's GG.

People were having so much trouble so I was expecting a nightmare and I ended up one shotting it!

Best way by far to deal with this boss is to stick to Bo like glue.

As a hunter I would FD aggro onto my pet then blow CD's while standing directly in front of Bo. Everytime they launched a rocket at me i would strafe around Bo so as not to be hit.

The idea is to have most of the damage on Bo be done by the rockets.

When Bo ports away to a shield you quickly run over and stand under the shield. 3 Rocket strikes will destroy it.

Dont bother swapping to the other guy. Just stay on Bo and dodge the rockets!

First encounter at Rank 7 in the Brawler's Guild.
I found it a very nasty champion.
In the end the way I did it, was to stand near one of the 2 gnome-goblins and let them trow their bomb towards me, and then let the bomb hit themselves. Whenever one of them went into protection I switched to the other.
