Dota 2 After 12 minutes of trying to break the last set of raxes with Techis chain minesLandmines have a half damage radius(500) and a full damage radius(200) in dota 2. The full damage radius is also the trigger radius, so if you place the mines within the trees 500 units away, they won't blow up. Then, accounting for half damage and armor of the rax, you stack enough mines hidden in the trees to one shot the rax, and you drag an enemy unit over to trigger them.
You only need 11 mines if there is no backdoor protection. Backdoor protection in dota 2 reduces all damage taken to 75%. Of course, you could detonate the mines when your creeps are in the enemy base (perhaps in another lane), but there's a higher chance the enemy would happen to use a glyph.
Hey I was the storm spirit in that dota 2 game. Techies was too scared to grab the creeps alone. When I was trying to grab the creeps I just started panicking like crazy, and as you can see if the video I did almost mess it up. Also this game of dota 2 was like 5500 average which makes it pretty crazy that this trick worked.
