This simple stone glows as bright as a candle when gripped in the hand. It functions as a magical weapon, able to harm all enchanted monsters for 1d4+1 points of damage when thrown. It adds +1 to attack bonus.

The stone contains the soul of a celestial being who wagered with a devil over whether a mortal would choose wisely in the face of temptation. As payment for the loss, the devil condemned his opponent to a thousand years in the form of a stone discarded in a stream.

Nearly a hundred years ago, a humble halfling named Alfred plucked a shiny stone from the creek near his home and was surprised to find it glowed as bright as a candle when held. He stuffed it in his pocket and sometimes brought it out as a curiosity, a minor magical device that helped him avoid tripping over tree roots while heading out to fish in the pre-dawn darkness.

He never told anyone else that the stone whispered to him, encouraging him to keep his faith and to always treat others with honor. Surely the stone could not truly be alive with a real consciousness, he thought. In some particular moments of weakness, Alfred was sure the stone had forcibly turned away an intrusive thought to insult another or to take more than his share at the annual harvest celebration.

One morning, he stepped past the old oak into a particular dark patch of shade, and he felt the bone-deep chill that comes from the touch of a Shadow, those terrible monsters who sap their victims’ strength. Reacting instinctively, he leaped backwards, pulled the stone from his pocket and hurled it at the nasty Shadow. No ordinary stone could harm such an enchanted creature, but the fortune favored that diminutive fisherman that morning. The magic of the stone dissipated the magical darkness of his foe. From that time, Alfred called his stone Shadowbane.

Stone +1
Glows as a candle when held. Intelligent (11 INT 12 WIS 15 CHA).

It was forged roughly a century ago and still appears new. A divine being made it to fulfill a divine wager. The item is utterly plain, its surface polished to a mirror sheen with no engraving or motif to betray the enchantement woven into its steel.
