A horn of plenty is one of the magical horns, but unlike the other horns, it cannot be used as a musical instrument.[1] It is created with 1 to 20 charges and it may contain up to 50 charges. When applied, it produces food (including royal jelly) or a potion of water, fruit juice, booze, acid, sickness or oil.[2][3][4][5] The BUC of the item produced is the same as the blessed/uncursed/cursed status of the horn.

1 in 13 applications (7.7%) will produce a potion, in the following ratios:

Potion Class Probability Overall Probability
potion of booze 18.6% 1.4%
potion of sickness 4.2% 0.3%
potion of fruit juice 18.6% 1.4%
potion of acid 4.4% 0.3%
potion of oil 13.3% 1%
potion of water 40.8% 3.1%

The remaining 92% of applications will produce food, in the following ratios (multiples may be created if the food code permits):

Item Class Probability Overall Probability
tripe ration 14% 12.9%
random egg 8.5% 7.8%
eucalyptus leaf 0.3% 0.3%
apple 1.5% 1.4%
orange 1% 0.9%
pear 1% 0.9%
melon 1% 0.9%
banana 1% 0.9%
carrot 1.5% 1.4%
sprig of wolfsbane 0.7% 0.6%
clove of garlic 0.7% 0.6%
slime mold 7.5% 6.9%
lump of royal jelly 5.4% 5%
cream pie 2.5% 2.3%
candy bar 1.3% 1.2%
fortune cookie 5.5% 5.1%
pancake 2.5% 2.3%
lembas wafer 2% 1.8%
cram ration 2% 1.8%
food ration 32.6% 30.1%
random tin, including spinach 7.5% 6.9%

In the tables above class probability is chance within class (potion or food), and overall probability is the chance relative to all possible items.

For Tourists

A blessed horn of plenty is a great item for a tourist since it can be recharged indefinitely with The Platinum Yendorian Express Card. While in a normal game one doesn't generally need the extra food, the ability to produce an indefinite amount of potions and food has several non-trivial uses:

  • The unlimited food and potion source can be essential in multi-conduct games. In particular, it makes the tourist a viable candidate for a liquid diet: a foodless atheist true polyselfless survivor (see the link below).
  • The potions can be used to provide an indefinite supply of holy water, or can be used for polypiling or alchemy.
  • Those attempting stupid ascension tricks such as death farming might prefer a horn of plenty to prayer as a food source, though prayer is easier to automate.
  • If smoky potions are one of sickness, fruit juice, or booze, acid, or oil, the horn can be used as a (slow) wish engine.
