I have a bunch of goblin land mines but whenever i place them it never does any dmg to the npc I'm trying to kill. I lay it down and the 10 sec armed timer counts down but then after the 10 secs nothing happens, it just lays there and shoots sparks out, never actually exploding or causing dmg I think.
How do I get it to work? Do I have to click on the actual mine for it to happen, click on the mine icon in my bag or what?
