Healing potions are potions of healing, extra healing, and full healing. They have similar effects.

Generation

All Healers start the game with 4 non-cursed potions of healing and 4 non-cursed potions of extra healing, all Monks start the game with 3 non-cursed potions of healing, and all Tourists start the game with 2 non-cursed potions of extra healing.

Shopkeepers have a 12 chance of being generated with potions of healing and extra healing (one of each kind), 14 chance of being generated with potion of healing only, and 14 chance of neither.[1] In addition, intelligent monsters, except Pestilence, may generate with a random healing potion as a defensive item.

In a health food shop, 4% of items are potions of healing, and 3% are potions of full healing.[2]

A random potion has 5.7% chance to be a potion of healing, 4.7% chance to be a potion of extra healing, and 1% chance to be a potion of full healing.

Description

Quaffing

Quaffing a healing potion will do the following:

Table 1. HP increase and maximum HP increase
Beatitude Potion of healing Potion of extra healing Potion of full healing
Blessed 8d4 and 1 8d8 and 5 400 and 8
Uncursed 6d4 and 1 6d8 and 2 400 and 4
Cursed 4d4 and 0 4d8 and 0 400 and 0

Table 2. What does it cure?
Beatitude Healing Extra healing or full healing
Blessed Bli, Sic Bli, Sic, Hal
Uncursed Bli Bli, Sic, Hal
Cursed Nothing Bli, Hal
  • Bli - Blindness and Deafness
  • Sic - Sickness and Vomiting
  • Hal - Hallucinations


Effects on a monster

Monsters can also quaff the potion to heal for the same amount, though it can only additionally cure blindness (unless it is a cursed potion of healing).

Monsters hit by the potion are fully healed and, if it was a blessed potion of healing, non-cursed potion of extra healing, or any potion of full-healing, are also unblinded.[4]

Pestilence is damaged by the potion, but the effects will always be completely resisted unless Pestilence is severely level drained first.[5]


Inhaling

Inhaling vapors from a healing potion of any beatitude will exercise constitution and heal 1, 2, or 3 HP for a potion of healing, extra healing, or full healing respectively.

In addition, inhaling the vapors can cure blindness and deafness. To do this, a potion of healing should be blessed, a potion of extra healing should be non-cursed, and a potion of full healing can be of any beatitude.

Alchemy

Using potions of gain level or gain energy, and potions of speed at the first step, you may turn healing potions into potions of full healing or gain ability, following the route:

healing → extra healing → full healing → gain ability

See List of alchemy recipes for more information.

Other dipping

Dipping a poisoned weapon into healing potions will remove the poison and use up one potion.

Strategy

The potion of healing is a decent resource for starting and early character; spellcasters are typically better off using the healing spell in most situations unless they are aiming to conserve power or reduce the weight of their inventory. Later in the game, when the potion's healing is less effective, you should consider alchemizing them into potions of extra healing, and then to full healing if possible. If saving speed potions for use in the late stages of the game, and/or reserving your other alchemy components for full healing potions, you can instead wield or throw healing potions at your pets, which always restores them to full health (although this is still considered abuse).

History

The potions of healing and extra healing first appears in Hack 1.21, a variant of Jay Fenlason's Hack; Hack 1.21 also has the potion of extra hit points, whose functions are effectively folded into the various healing potions in Hack for PDP-11 and PDX. The potion is included in the initial item list for Hack 1.0.

The potion of full healing first appears in SLASH 6, and makes its vanilla debut in NetHack 3.3.0.
