Dust of Deliciousness

The Dust of Deliciousness is a reddish-brown dust that, when sprinkled on any edible substance, greatly improves the flavor. It also dulls the senses of the consumer, giving them disadvantage on wisdom-based checks and saves for one hour.

Jester Lavorre purchased a sack of the Dust of Deliciousness from Pumat Sol while she and the Mighty Nein were shopping at The Invulnerable Vagrant.

While the Mighty Nein was visiting the home of Isharnai to negotiate a deal with her to remove her curse preventing Nott from changing back from goblin to halfling, Jester persuaded the sage to split a cupcake with her. Unbeknownst to Isharnai, the cupcake was sprinkled with the Dust of Deliciousness. Because of this, Jester was able to successfully cast Modify Memory on her, making the sage believe that she agreed to remove Nott's curse.

Trivia

 * Matthew Mercer mentioned that, as a Dungeon Master, Laura Bailey's trickery in making Isharnai eat the cupcake spiked with the Dust of Deliciousness was "one of [his] more frustrating moments", but also "one of the most proud [he's] been of a player outsmarting [him]".
