Aroben's Taunting Tale

A creature of your choice that you can see within range becomes enthralled by your storytelling abilities. The target immediately becomes incapacitated and falls prone, unable to stand up for the duration. 

At the end of each of its turns and each time it takes damage, the affected creature can make a Wisdom saving throw. If it succeeds, this effect ends for that creature.

After the spell ends, the affected creature can't get the story out of their mind, even after its told and must roll a d4 and subtract the number rolled from any attack or saving throw for the next hour.
