If you're talking about Landmine traps, those don't take your HP down to 0, unless you got popped by a scumbag pox that fully disables your HP regen or you're already in combat. It puts you in a dangerous spot, yeah but I've yet to see a trap that will OHKO a player. Now, if you were one of those unlucky schmucks that stepped on a landmine right next to a bomb box, then RIP my dude.
