Rod of the Last Nail

A blunt rod of black iron bears a single square nail head protruding from its side, as though driven halfway through the metal and abandoned there. The rod is always cold, but the nail itself grows warm near fresh death, and faint lines beneath its surface resemble veins trapped inside forged iron.

Only wizards and clerics may command it. Each charge draws the nail out and sets it against a creature dead less than a minute, returning it to life at 1 hit point with a line of iron left under the skin. No creature can be brought back this way twice.
