First time playing and DM’ing. Party enters a dark area with the wizzard throwing a ball of light that illuminates 4 squares in either direction (they neglected to get any tourches.) They find a rune on the floor but all fail checks to know what they were. So they send a npc with them to test it. After he triggers the rune and all take damage they check the rune again and find it is touch activated. After some thought they asses that the zobmies they had killed did not tridder the rune so they start to drag corpses to cover the rune and walk accross the bodies. I liked it so it worked. They find another rune and another. So this whole room/maze they are dragging a pile of rotting corpses with them.
