Brewmaster is a very powerful strength initiator with a unique but effective skillset, and is best played midlane.

Generally combo like this: Blink>Thunderclap>Primal Split
If you have Shivas/BKB, cast those before Blink, and if you have any summons, use those after Blink

Remember to use storm's cyclone!

The aghs earth spirit's thunderclap has a separate cooldown from Brew's, so you can cast two thunderclaps when your ult starts, and when it ends. Same for the drunken haze on aghs storm spirit.
