Bartleby's Befuddling Bolt of Bewilderment

On a 1 the target gains the benefit of the spell Haste until the end of your next turn, when the spell ends the target is not effected by lethargy.

On a 2 the target must make a wisdom saving throw, If it fails the saving throw, it is charmed by you until the end of your next turn or until you or your companions do anything harmful to it. The charmed creature regards you as a friendly acquaintance. When the spell ends, the creature knows it was charmed by you.

On a 3 the target must make a constitution saving throw, if it fails the target takes 3d6 poison damage and is poisoned, a poisoned creature has disadvantage on Attack Rolls and Ability Checks.

On a successful save, the target takes half as much damage and suffers none of the spell’s other effects.

On an 11 the target gains the benefit of a death ward for up to 8 hours. The first time the target would drop to 0 hit points as a result of taking damage, the target instead drops to 1 hit point, and the spell ends.
