Key strategic elements to consider when playing Techies:

• Use spells to quickly push out the wave and secure the rune that`s about to spawn without missing farm.
  
• Ferry some health consumables with your courier to use Blast Off! frequently.
  
• Blast Off! destroys trees which can be useful against certain heroes and when opponents try to hide in trees.
  
• Look to place a couple of Proximity Mines around portals for a surprise burst on enemies using them.
  
• You can make it harder for opponents to destroy mines by sitting on top of them.
  
• Drop or backpack items that provide you with mana before using Arcane Boots, Bottle or Soul Ring.
  
• Sticky Bombs and Proximity Mines provide a little vision so you can scout cliffs and highgrounds, runes or the Roshan pit.
  
• Consider Smoke of Deceit on yourself and moving to the opponents` side of the map to mine aggressively. Bring an Observer Ward as well.
  
• Look for pickoffs or join teamfights with your massive burst potential.
  
• If your teammates are pressuring, move with them, Mine around them and Blast Off! when opponents clump up.
  
• Place a couple of Proximity Mines at the entrance of Roshan pit to scout enemy movement.
  
• Pick up Aghanim`s Shard for extra damage on your Reactive Tazer adding additional burst to your combo.
  
• Consider using Force Staff on enemy heroes to push them into Mines.
  
• With Ethereal Blade, you can burst down just about any hero on the map with your combo.
