Mine

"Plan an explosive surprise for troops that get too close. Choose air or ground!


 * Summary
 * Mines are inexpensive traps that remain hidden until they are activated by an attacking troop moving into their trigger radius.
 * Although they are the weakest of all the Traps, Mines can still have a positive impact on the effectiveness of a village's defense if properly placed.
 * Even though Mines are classified as "Defensive Buildings", they are not buildings and do not need to be triggered/destroyed for your enemy to reach 100% destruction (nor do they count toward it).
 * The Mine explodes after an enemy comes within 3 tile of it, causing splash damage to every enemy ground troop within 5 tiles. This delay means that you'll want to place the bomb in an area where troops are likely to remain for a period of time, like right next to a building they're attacking.
 * By itself, a single Mine will not do a great deal of damage to even the weakest of Troops (although every bit helps). However, several Mines in a cluster can significantly damage or even destroy an entire group of Archers or Barbarians.
