Succubus' kiss is a dagger forged by Ammon Jerro, one of the most powerful warlocks in the history. He forged the dagger from the remains of the Silver Sword of Gith, which was broken in the battle against the King of Shadows. To give him an advantage in a future battle, Ammon quenched the dagger with the blood of his pit-fiend slave, succubus Blooden.
The blood of the succubus gives the wielder the power to drain a victim of their life force. Every strike at the victim deals a 2d12 psychic damage, or, if the victim got away, deals a 2d12 psychic damage per day until the victim dies. Only once the victim is dead, can the dagger "kiss" another person. The dagger itself deals 2d4 + 4 slashing damage.
While the victim is alive, the wielder of the dagger gets 1d4 temporary hit points per day, but it comes at a cost. When the dagger kisses someone, it also bites the wielder, leaving a bitemark between the thumb and the index finger. While the victim is alive, the bite mark stays fresh.
To heal a living victim of the Succubus' kiss, a superior healing potion must be prepared, and the blood of a succubus or incubus must be added to it during the brewing process.
