Not only is this trap designed to harm the victims physically, it will also teach an unfortunate tomb robber the true meaning of loss and despair.
How the trap works
The three trapdoors opens when (and only when) pressure is applied to all three simultaneously. This means that the trap will trigger only when there is a victim on top of each trapdoor, dispersing them in one pit each. Two of the victims will fall into the lairs of giant dungeon centipedes (feel free to switch to other monsters if you wish). The third one will have to helplessly watch through the iron bars as his comrades perish.
All hope might not be lost, though! Perhaps the adventurers falling into the monster lairs are mighty warriors able to fend off the abominations. Perhaps the trapped man or woman in the middle can lay down fire support by spell or missile weapon? Maybe after all there is treasure and glory at the end of this nightmare?
