Gluttonous Crumhorn
Wondrous item, legendary (requires attunement by a bard)
While holding this horn, you gain a +3 bonus to spell attack rolls and to the saving throw DCs of your bard spells. The crumhorn has 6 charges. It regains 1d4+2 expended charges daily at dawn.
As an action you can expend 1 charge to play the crumhorn and release an eerie, stomach-growling tune. Any creature, other than yourself, within 60 feet of you that can hear your tune and that has the ability to eat, must succeed on a Constitution saving throw or go into a ravenous frenzy. On its next turn, a ravenous creature must move up to its speed to the nearest source of food and use its action to shovel anything edible into its mouth. It will consume food at an alarming rate, eating up to its daily requirement with each action. At the end of each turn that a ravenous creature spends eating before it takes a long rest, the following effects occur:
If a ravenous creature does not have access to food, it will attack the nearest creature it perceives to be edible. At the end of its turn, if a ravenous creature has not eaten food, it takes 4d6 necrotic damage. If there is nothing edible within range, a creature under this effect will eat leather, and other organic objects that are normally considered inedible, although this does not prevent the creature from suffering the necrotic damage. Undead and creatures immune to being charmed aren't affected by this song.
Alternatively, as an action you can expend 2 charges to play a joyous tune of abundance from the crumhorn and cast the create food and water spell.
“The man told us it was dinner time, and he began playing a tune on that strange instrument of his. We suddenly became hungry, so unbelievably hungry. The rest is too horrible for me to recall... I’m a vegetarian now.”
