The trap dealing insane damage when detonates by direct hit after place them, I think Larian wants to make the mine functional after depolyed. However, a direct detonates of undeployed mine by attack deals tremendous damage depend on the trigger(attacker) , at character level 17, lvl 14 summon specialist using fire slug can deal 10000+ fire damage in 3m area by a single hit to detonate 4 mines.
