You sheath your weapon in negative energy, allowing it to deliver withering wounds.

Target one weapon you touch. For 1 round + 1 per level, whenever that weapon deals damage, it deals an additional amount of negative energy damage equal to your CHA modifier and the target must succeed on a Fortitude save or suffer ongoing negative energy damage equal to your CHA modifier (save ends).

At 9th level, the ongoing damage increases to twice your CHA modifier.

At 18th level, the ongoing damage increases to three times your CHA modifier.
