Heal · Game Mechanic Compendium

Definition

A heal is an ability a character uses to return lost hit points to itself or an ally, never above the maximum. The hit points mechanic covers the pool itself, the subtraction of damage, and what happens at zero; the heal is only the deliberate restoring act and the limits placed on it. Passive regeneration involves no act, and recovery by rest or at an inn is a procedure rather than an ability, so neither is a heal. Resurrection, which returns a dead character, temporary hit points above the maximum, and pure condition removal such as Cure Disease are neighbouring archetypes.

Behaviour

The canonical form targets one wounded character, often the user, and restores a rolled or fixed amount. In 1974 Cure Light Wounds takes one full turn and removes 2 to 7 points of damage. Turn-based games make the heal compete with attacking: Dragon Quest’s HEAL in battle and HeroQuest’s healing spells take the place of the user’s attack, and HeroQuest requires a visible target. Real-time games add cast times and range, as with World of Warcraft’s Lesser Heal at 1.5 seconds and 40 yards. In World of Warcraft healing also generates threat.

Variations

Graded tiers (Dungeons & Dragons, Wizardry, Final Fantasy): rising strengths unlocked by level (Cure Light to Cure Serious Wounds, DIOS to MADI, CURE to CUR4).
Heal over time (World of Warcraft): Renew spreads its restoration across 15 seconds.
Channelled beam (Overwatch 2): Mercy’s staff heals continuously while held on an ally.
Area heal (Overwatch 2): Ana’s Biotic Grenade heals every ally in its area.
Cleansing heal (Gloomhaven): Heal removes Wound and then restores hit points, or removes Poison instead of restoring them.
Item heal (Dungeons & Dragons, Dragon Quest): a potion or herb gives the effect to characters who cannot cast it.
Capped heal (Fortnite): Bandages stop at 75 of 100 health, so the rest needs a slower item.
Inverted heal (Wizardry): BADIOS, “the inverse of DIOS”, damages a monster.

Gating

The 1974 heal is a memorised daily allotment counted per spell level, behind a level gate: a cleric holds no spell at 1st level. Early computer role-playing games keep per-level counts, Wizardry as spell points and Final Fantasy as uses per level, both refilled at an inn, while Dragon Quest moves to one MP pool shared by every spell. Board games ration heals by cards: HeroQuest allows each spell once per quest and discards it, at the cost of the turn’s attack, and Gloomhaven’s heals reportedly sit on cards recovered by resting. World of Warcraft gates heals by mana and cast time. Overwatch 2 leaves Mercy’s beam at will and moves burst and area healing to cooldowns and an ultimate meter. A consumable equivalent, potion, herb, or card, accompanies the spell in almost every example.

History and provenance

The earliest documented heal is Cure Light Wounds in Men & Magic (1974), published with a Potion of Healing defined as “just like a Light Wound spell”. Chainmail (1972) has no healing rule. The cleric class is often credited to Arneson’s Blackmoor campaign, an unpublished antecedent of which no copy is cited. Wizardry (1981), which a contemporary review called the truest computer program to Dungeons & Dragons and on which the creators of Dragon Quest and Final Fantasy drew, is an early documented computer-game heal, still counted per spell level; healing in PLATO dnd (1975) and Rogue (1980) is unconfirmed. The names split between cure (Dungeons & Dragons, Final Fantasy) and heal (Dragon Warrior, World of Warcraft, Gloomhaven).

Notable examples

Notable examples, in chronological order. Notes describe how the ability behaves in each game; gating is what limits its use there; the latest reference is a widely played game from 2020 or later.
Game	Year	Medium	Gating	How the ability behaves
Dungeons & Dragons Gary Gygax and Dave Arneson (TSR)	1974	Tabletop RPG	Spell slots, Consumable	Cure Light Wounds, a cleric 1st-level spell, removes 1d6+1 (2 to 7) points of damage from one wounded character over one full turn; Cure Serious Wounds (4th level) removes 4 to 14. Each memorised spell is used once a day, and a cleric has a 1st-level spell only from 2nd level. A Potion of Healing restores the same 2 to 7 points.
Wizardry: Proving Grounds of the Mad Overlord Sir-Tech	1981	Video	Spell slots, Consumable	DIOS, a level 1 priest spell glossed "heal", restores one to eight lost hit points to one party member and can be cast at any time; DIAL restores 2 to 16 and MADI restores all. Each cast spends a spell point of that spell level, refilled at the inn, and DIOS potions heal without one.
Dragon Quest Chunsoft (Yuji Horii)	1986	Video	Mana, Consumable	HEAL, learned by level and usable in battle or while exploring, costs 4 MP and restores 10 to 15 HP by the 1989 North American manual (about 10 to 20 by its Explorer's Handbook); in battle it takes the turn's attack. HEALMORE restores 75 to 100, and Herbs give a purchased item alternative.
Final Fantasy Square	1987	Video	Spell slots, Consumable	White Magic CURE (level 1) recovers a little HP for one ally, CUR2 (level 3) 32 to 64, CUR3 64 or more, and CUR4 all. Spells are bought in shops, up to three per level, and each level has its own count of uses, restored at an inn. HEAL potions are the item form.
HeroQuest Stephen Baker (Milton Bradley and Games Workshop)	1989	Board & card	Per rest, Consumable, Action cost	The Wizard or Elf casts a healing spell instead of attacking, on a visible target or on themselves; each spell is cast once per quest and its card is then discarded. Healing spells and potion treasure cards restore lost Body points but never above the starting level.
EVE Online CCP Games	2003	Video	Mana	Fitted modules repair damage to separate hit-point layers, each drawing capacitor when activated. Armour repairers and shield boosters work on the user's own ship, and remote repair systems and shield transporters repair another ship's armour or shields.
World of Warcraft Blizzard Entertainment	2004	Video	Mana	The priest's Lesser Heal at rank 1 costs 35 mana, has a 40-yard range and a 1.5-second cast; higher ranks cost more mana and take longer to cast. Renew heals over 15 seconds for 30 mana. Healing adds threat, and a Minor Healing Potion restores 70 to 90 health.
Gloomhaven Isaac Childres (Cephalofair Games)	2017	Board & card	Per rest, Consumable	Heal X returns X hit points to the user or one ally within range, or to the user only when marked Self. On a poisoned figure it removes Poison instead; on a wounded figure it removes Wound and then heals. Heals reportedly sit on ability cards that are discarded and recovered by resting, or lost; a long rest includes Heal 2, Self.
Fortnite Epic Games	2017	Video	Consumable	Healing comes only from items. A Bandage takes 4 seconds and restores 15 health but cannot raise it above 75 of 100, a Med Kit takes 10 seconds and restores all health, and the placed Cozy Campfire heals 2 health a second for 25 seconds to anyone near it, enemies included.
Overwatch 2 Latest Blizzard Entertainment	2022	Video	At will, Cooldown, Ultimate charge	Mercy's Caduceus Staff heals an ally with a beam held on it at no resource cost, 45 health per second since February 2023 (55 before) and 50 percent more on allies below half health. Ana's Biotic Grenade, on a cooldown, heals allies in an area and raises the healing they receive; Mercy's ultimate, Valkyrie, enhances her abilities.

Provenance

Earliest documented use: Dungeons & Dragons (1974), tabletop rpg. Confidence: high. Cure Light Wounds, a cleric 1st-level spell in Volume 1, Men & Magic, removes 2 to 7 points of damage from a wounded character; the same box holds a Potion of Healing defined as "just like a Light Wound spell" and a Staff of Healing usable once a day per recipient. Chainmail (second edition, 1972) has no healing rule; its only restoration is the recovery of fatigued troops after a turn without movement. The cleric class is often credited to Dave Arneson's Blackmoor campaign (about 1971 to 1973), an unpublished antecedent of which no copy is cited. Among video games, Wizardry (1981) is an early documented heal spell; healing in PLATO dnd (1975) and potions of healing in Rogue (1980) are unconfirmed.

Established form: Dungeons & Dragons (1974), tabletop rpg. The earliest documented use also set the form. Confidence: low. Cure Light Wounds and Cure Serious Wounds set the deliberate heal in graded tiers, with a potion as its item form. The documented chain runs through Wizardry, which a 1981 Softalk review called the truest of computer programs to Dungeons & Dragons and whose DIOS, DIAL, and MADI repeat the grading, to Dragon Quest and Final Fantasy, whose creators drew on Wizardry. No source cited traces the heal itself along that chain.
