Techies: How to stack mines | Dota 2 Guides

One of the more advanced techniques available to Techies is "mine stacking": placing mines directly one on top of the other so that the enemy can't tell how many mines there are at a location even if they have True Sight. In wc3 DotA this wasn't difficult to accomplish because you could portrait cast. This doesn't work in DotA 2, making life significantly more difficult. However, I did figure out a way around that:

Land Mines

• Step 1 : Lay a Land Mines, select it, and make it a control group.
• Step 2 : Enter showcase mode and rotate it to look directly downwards.
• Step 3 : Select Techies and press Q (or whatever your Land Mines hotkey is).
• Step 4 : Hit the Land Mines's control group key.
• Step 5 : Target the center of the spike on top of the mine then click.

This will put the second mine exactly on top of the first, or close enough that the enemy can't tell.
Remote Mines are much more difficult to stack this way because they are assymetrical and lack a marker for their center. Fortunately, you can get around this by centering the cursor using the Land Mines then changing control groups to get to the Remote Mines you lay.

Remote Mines

• Step 1 : Lay a Land Mines, select it, and make it a control group.
• Step 2 : Lay a Remote Mines, select it, and make it a different control group.
• Step 3 : Enter showcase mode and rotate it to look directly downwards.
• Step 4 : Select Techies and press R (or whatever your Remote Mines hotkey is).
• Step 5 : Hit the Land Mines's control group key.
• Step 6 : Target the center of the spike on top of the mine.
• Step 7 : Hit the Remote Mines's control group key, wait a second for the camera to stabilize, then click.

Unfortunately, even if you stack them perfectly it will usually be fairly obvious when Remote Miness are stacked in DotA 2. This is because the flashing light on top of each mine will flash separately (unless you have really, really good timing) which is a dead giveaway that there is more than one mine there.
