Healing

After losing Health, it can be healed back in various ways!

Healing Formula

The following fully expanded formula can be applied to all types of Heals, though not all types will be affected by every part of the formula. See each healing subsection for specifics.

Instant Base Heals:
Total Healing = (Base Heal + Physical/Magical Healing Add * Scaling) * (1 + Physical/Magic Power Bonus * Scaling) * (1 + Physical/Magical Healing Mod)

Heal over Times (see link for specifics):
Total Healing = (Base Heal + Physical/Magical Healing Add * Scaling) * (1 + Physical/Magic Power Bonus * Scaling) * (1 + Physical/Magical Healing Mod) * floor(Duration Base * (1 + Buff Duration)) / Duration Base

Healing Add

Adds to the base heal. Examples include, but are not limited to:

Affects both Magical/Physical Base Healing, but not any other healing types.

Affected by Scaling.

Power Bonus

Multiplies the healing dealt. Affects only Magical healing, and not Physical Healing nor any other healing types.


Affected by Scaling

Healing Mod

Multiplies the healing after Power Bonus.

Affects all sources of Healing, without any known exceptions.

Examples include:

Not affected by Scaling.

Potion Chugger

Barbarian's Potion Chugger perk does not apply Healing Mod, but instead applies a final multiplier applied at the end of the calculation. This is left out of the formula for simplicity. As such, Potion Chugger stacks multiplicatively with Healing Mod. For example, if Vampirism and Potion chugger were combined (requires Multi-classing), it would be a total of 1.2*1.2 = 1.44x Healing - so, effectively the same as .44 Healing Mod.

Not affected by Scaling.

Magical Base Healing

Magical Healing is utilized by Cleric's heal spells, Warlock's Torture Mastery, healing potions, Troll's Blood, healing shrines, and more.

All Magical Healing benefits from both Magical Healing Add and Magical Power Bonus but with varying Scaling, and is affected by Healing Mod at the end of the calculation.

Note that Sanctuary is not a Heal Over Time but rather a channel, therefore it scales per tick (1s base) channeled. Torture Mastery is also not a HoT but a new instance of healing every second that the target receives damage from Curse of Pain / Power of Sacrifice.

Barbarian's Potion Chugger perk alters healing potions to heal for 20% more health.

Following list is not meant to be exhaustive, scaling on each can be found on their respective pages Scaling info:

Examples

Torture Mastery

Torture Mastery (2 base) with 5 Magical Healing Add, 30% Magical Power Bonus, and the Vampirism perk will heal for

Heal per second = (2 + 5 * 0.1)(1 + 0.1 * 0.3) * 1.2 = 3.09 HP per second

Healing Potion

For example with a Common Healing Potion, 4 Magical Healing Add, +6% Buff Duration, 0% Magical Power Bonus, at a base of 15 health over 30 seconds with Vampirism:

Total Healing = (15 + 4 * 0.5) * floor(30 * 1.06) / 30 * 1.2

= 17 * 31 / 30 * 1.2

= 21.08 health over 31s

Note that this does in fact heal 21.08 health and not 21 nor 22 as there is decimal HP, although the health display in-game always rounds up. See Damage Calculation for more. Also note that the duration actually lasts 31.8s, but effectively only 31s of healing occurs.

Potion Chugger

Barbarian's Potion Chugger perk gives 1.2x Healing as a Final Multiplier.

Using the same example but now with Potion Chugger:

Total Healing = (15 + 4 * 0.5) * floor(30 * 0.5 * 1.06) / (30 * 0.5) * 1.2

= 17 * 15 / 15 * 1.2

= 20.4 health over 15s

Note that the duration actually lasts 15.9s, but only 15s of healing occurs.

Physical Base Healing

Physical Healing is utilized by Campfire Kits, Bard's Jolly Time, Ranger's Field Ration, Surgical Kits, and more.

Physical Healing scales with the Physical Healing Add enchantment but NOT with Physical Power Bonus.

Since Campfire Kits are not a Buff, they receive 100% scaling on Physical Healing Add per second, rather than to the total amount.

Following list is not meant to be exhaustive, scaling on each can be found on their respective pages Scaling info:

Examples

Campfire

Using a Common Campfire with 1 Physical Healing Add will heal (3+1) HP per second for 21 seconds, unaffected by the Buff Duration stat, totaling to 84 health.

True Base Healing

True Base Healing is not affected by Healing Add nor Power Bonus, but is by Healing Mod.

Examples of this include, but are not limited to:

  • looking for examples

Contrary to common belief, Warlock's Shadow Touch is not True Base Healing. It is in fact just Base Healing with 0% Scaling.

Recoverable Healing

Recoverable Health.png

Recoverable Health can be healed by converting it into actual health.

When receiving damage/healing (most notably damage), a portion of it will become recoverable, denoted as the darker red part of the health bar.

Recoverable Health cannot prevent death on its own, but it can be converted to actual health using Bandages, Resting, and Tranquility. Recoverable Health is tracked separately from normal HP, and can "overflow" above the player's maximum HP. This means that if the player only heals with conventional healing methods, they can "store" some amount of Recoverable Health over the course of a single life.

Damage/Heal sources have different Conversion Rates that will add a percentage of the incoming amount as recoverable health.

  • Player/Monster Damage: 65%
  • Damage over Times: 65%
  • Death Swarm: 100%
  • Warlock's Spell's Health cost: 100%
  • Bandages -100%
  • Resting -100%
  • Bard's Tranquility -100%


Note that some are negative because they convert it into actual health rather than damaging you.

The Recoverable health pool is increased by a portion of the health change. However, if your recoverable health pool exceeds your missing health afterwards, it instead sets your recoverable health pool equal to your missing health. Note that the recoverable health pool is only updated when you receive damage or use a Bandage/Rest/Tranquility, and not when you are True Healed, Percent Max Health Healed, nor given Temporary Max Health. This can be expressed as:

New Recoverable HP Pool = min(Old Recoverable Pool + Conversion Rate * Damage or Heal Amount, New Missing Health)

Recoverable Health never has any Scaling

Resting

When Resting, the player will heal 1 Recoverable Health every two seconds which cannot scale. (This is not 0.5/s, it is specifically 1 every 2 seconds.)

As of Hotfix 25, standing up from resting no longer removes your remaining recoverable health, so you can stand up without a worry and continue your resting at a more opportune time.

Tips

  • Entering Inferno will set Recoverable HP to 50% (needs further testing) of missing health.
  • Dying will remove all Recoverable HP if later revived.

Examples

1. Starting at 80/100 HP with 15 Recoverable HP, Bandaging for 10 will heal you to 90/100 HP, and your recoverable HP will be set to

min(15 + -1*10, (100-90)) = 5

2. Starting at 80/100 with 15 Recoverable, then being true healed to 100/100, you will retain the same 15 recoverable HP. Later, you are damaged for 40 by a monster, down to 60/100 health with a recoverable HP pool of

min(15 + .65*40, (100-60)) = 40

3. Starting at 80/100 with 15 Recoverable, then being true healed to 100/100 with 15 recoverable, and finally being damaged for 70 by a monster. Your new HP is 30/100, with new recoverable HP pool of

min(15 + .65*70, (100-30)) = 60.5

4. Starting at 100/100 with 50 Recoverable, then bandaging for 10 will set your recoverable HP to

min(50 + -1*10, (100-100)) = 0

Percent Max Health Healing

Following other trends, this can be considered a Base Heal, as it creates a new Heal instance. This does not mean the Heal is based on your Base health.

Percent Max Health Healing will heal a percentage of your current maximum health, and never scales with Physical/Magical Healing Add nor Magical Power Bonus, but does with Physical/Magical Healing Mod. The current sources of this are Barbarian's Morale Boost & Blood Exchange, Fighter's Victory Strike & Second Wind. Second Wind, however, is also in the form of a heal over time, therefore you can receive more healing with longer buff durations.

Being neither Physical nor Magical, it cannot scale from Physical/Magical specific sources. However, is affected by Healing Mod, even when negative, like Heal Reduction.

The Heal amount can also be negative, representing Percent Damage, such as Lich's Curse of Gathering/Isolation, Warlock's Blood Pact's passive aura Abyssal Flame, or even Barbarian's War Sacrifice. Similarly, these are not scaled by Physical/Magical modifiers nor affected by Cleric's Perseverance perk.
When this is negative, negative Healing Mod does not affect it. When this is negative, it is unknown if positive Healing Mod will affect it.

Examples

Using Second Wind's 40% Percent Max Health Damage/Healing Over a Time of 12s with 10% Buff Duration on a Fighter with 100 Max Health:

Total Duration = 12 * (1 + .1) = 13.2 seconds

Total Heal = .4*100 / 12 * floor(13.2) = 43.33 health

Other Healing

Life Steal

Warlock's Life Drain ability heals the player equal to the damage dealt in a lifesteal fashion. No modifiers affect this except Healing Mod as it is based on outgoing damage dealt (meaning before reductions like Magical Damage Reduction).

Heal Reduction

Heal Reduction is in the form of negative Healing Mod, see Healing Mod for specifics.

Examples of negative Healing Mod include, but are not limited to:

Unknown on how negative Healing mod interacts with negative Heals.


(Needs more testing). Interestingly, these cannot be applied at the same time. If both debuffs are applied, the Heal Reduction value will not be overwritten, but the duration will be overwritten, even if the duration of the second status is shorter.

Goblin Mage's homing orbs and Famine, the Unique axe, seem to work separately to Healing Mod as they reduce all types of Healing, including Recoverable healing, by 100%.

Heal reduction seems to currently be bugged and is not reducing by the amount listed, sometimes more, sometimes less - more testing in progress

Outgoing vs Incoming

All healing sources are applied from an outgoing source, and when the target receives them, they are the incoming target. For example, if a Cleric heals a Warlock, the Cleric is the outgoing source, and the Warlock is the incoming target.
If a Warlock heals themselves, they are both the outgoing source and the incoming target. The base heal and all modifiers may be applied to either Outgoing or Incoming. For example, Cleric's Advanced Healer and +Magical Healing enchantment buff specifically outgoing healing. If that Cleric heals another player or themselves it will be buffed by both, since the Cleric is the outgoing source. If the incoming target has the +Magical Healing enchantment, however, they will not receive bonus healing.

Note that since all heals will be either Outgoing or Incoming, all bonuses/reductions will affect a player that is healing themselves as they are both the Outgoing and Incoming target. However, this is before Scaling is taken into account, some heals have 0% Scaling in which case it does not matter regardless.

History

  • Patch #2 Hotfix 27
    • Surgical Kit is now True Physical Healing instead of Percent Max Healing, and is therefore affected by Heal Reduction
  • Patch #2
    • Healing potions and Troll's blood are Magical now instead of Physical
    • Blow of Corruption and Fire mastery now affect incoming healing instead of outgoing, and also affect Percentage healing.
