Editing HealingGive feedback

'''Healing''' is the act of recovering a unit's current [[health]], which includes various methods such as [[Lifesteal]], [[Health Regen]], and [[Item]] effects.

== Overview ==
The most reliable way for a player to heal themselves is by killing a [[Trooper|Medic Trooper]] and picking up their Medic Pack, or by going back to their team's base, which has a constant source of healing. Alternatively, they can buy Healing or [[Lifesteal]] items. Some heroes also have healing abilities. See a full list of healing sources below.

Besides direct healing, players passively recover health at all times through [[Health Regen]].

== Healing Amp ==

Healing Amp, also known as Healing Effectiveness, is a [[Stats|stat]] which increases the amount of healing a hero does with their [[abilities]] and [[items]]. This affects both healing to themselves and to their allies. Healing Amp affects healing-over-time buffs, such as {{ItemIcon|Healing Rite}}'s active effect.

This [[Stats|stat]] is represented as a percentage. For example, a 25% gain would increase a heal of 100 to 125.

== Healing Reduction ==
Healing Reduction is a negative effect which reduces the effectiveness of healing on the unit it is applied to.

Healing Reduction is represented as a percentage and stacks multiplicatively, meaning each additional source has diminishing returns.

If a player is hit by the same source of Healing Reduction before its effect has worn off (e.g. two or more enemy players with {{ItemIcon|Healbane}}), only the first source is applied.

== Calculation ==

=== Calculating Healing Reduction ===
Multiple sources of Healing Reduction stack '''multiplicatively''':

<math>\text{Total Reduction} = 1 - (1 - R_1) \times (1 - R_2) \dots</math>

'''Example:'''
If two sources of Healing Reduction are applied, one providing '''40%''' and another providing '''40%''':
# Convert percentages to decimals: 0.40 and 0.40.
# Subtract from 1: (1 - 0.40) = '''0.60''' and (1 - 0.40) = '''0.60'''.
# Multiply the remainders: 0.60 × 0.60 = '''0.36'''.
# Subtract from 1: 1 - 0.36 = '''0.64'''.
# Total Healing Reduction is '''64%''', not 80%.

=== Calculating Final Healing ===

<math>\text{Final Healing} = \text{Initial Healing} \times (1 - \text{Total Reduction}) \times (1 + \text{Healing Amp})</math>

'''Example:'''
A heal of '''200 HP''' is applied to a target with '''64%''' Total Healing Reduction. The healer has '''25%''' Healing Amp.
# Apply Reduction: 200 × (1 - 0.64) = 200 × 0.36 = '''72 HP'''.
# Apply Amp: 72 × (1 + 0.25) = 72 × 1.25 = '''90 HP'''.
# Final Healing received is '''90 HP'''.

== Sources of direct healing ==
Killing a [[Trooper|Medic Trooper]] drops a Medic Pack that heals nearby players based on the following formula:

''Heal = ({{MiscData|medic_trooper_aoe_health_pickup_amber|MissingPctRegen|Base}}% of hero's missing [[Health|HP]] + {{MiscData|medic_trooper_aoe_health_pickup_amber|RegenFixed|Base}} HP + {{MiscData|medic_trooper_aoe_health_pickup_amber|RegenFixed|PerMinuteAfterStart}} HP per minute) / Number of nearby heroes''

The team's base heals players by increasing their [[Health Regen]] to {{DataProp|Convar|citadel_player_regen_zone_bonus_pct}}% of their maximum [[health]] per second plus {{DataProp|Convar|citadel_player_regen_zone_bonus_base}} health per second.
