Prisoner's Flail (Patreon)

Weapon (flail), uncommon

This flail is rudimentary in construction, having been made from a sharpened branch and an iron ball and chain. The anguish of untold prisoners has imbued the ball and chain with a miserable semblance of magic. When you hit a humanoid with this weapon, that creature's speed is reduced by 10 feet, or 20 feet if the attack scored a critical hit. The reduction lasts until the start of your next turn, during which time this property of the weapon can't be used again. For the duration of the effect, a spectral ball and chain trails behind the affected creature.

If you could force me to bear it for fifteen years, you can afford to carry it for a moment.
