Here's a guide on Roaming Techies, probably the most efficient way to play this hero in your pubs. Use Blast Off! and Proximity mines to win your lanes and to set up ganks, and deny areas of the map with your mines. In this build, we max Proximity Mines and Blast Off! first, as getting them maxed out as soon as possible is the best way for a Techies to be impactful in the Early/Early-Mid Game. Techies is a hero that relies heavily on your map awareness. Nobody expects a roaming techies, and what's more, nobody expects him to be good. Prove Yourself!
