Path of Exile: Life Leech

Leech recovers an amount of life, mana or energy shield over time, relative to the damage inflicted on an enemy. Leech cares about the damage taken by the enemy, not the amount of life removed.[1][2]

Mechanics

All leech mechanics act the same way for life, mana, or in the case of Ghost Reaver, energy shield. Examples in this article will use life, but if the character has equal statistics for a different resource (mana or energy shield), they will apply in the same way.

Whenever a character hits an enemy while having an applicable source of leech, a leech instance is created on that character. Each leech instance is independent, and will heal the character for Damage Dealt * #% damage leeched as life , at a default rate of 2% of that character's maximum health per second. Thus, each leech instance will have a different duration, calculated as (HealAmount / (MaximumHealthPool * 0.02) ). Each leech instance will stack and apply to the character simultaneously until it expires or the character is at full life. However, if the total leech per second from all leech instances is greater than the character's leech cap, the extra healing will be ignored.[3] By default, this cap is 20% of that character's maximum life pool. This is covered in greater detail under the Combined Recovery Rate section.

Leech grants recovery to the entity that hit the target, so leech on a minion or totem will grant recovery to that minion or totem, not you. Leech on a trap or mine has no effect, as the source of the hit has no life to recover. Exceptions to this rule include The BaronThe Baron

Modifiers

Leech can be modified significantly through passives, support gems, and equipment. Beyond just adding various sources of leech, modifiers such as #% of maximum Life per second to maximum Life Leech rate or #% increased (or reduced) Life Leeched per second can change how leech is applied to a character.

The #% increased (or reduced) Life Leeched per second modifier provides an increase to how much life per second a character will regain from each leech instance, without changing the duration of the leech instance. This will increase the total amount healed by that leech instance. If previously a leech instance would heal your character for 100 health over 1 second, and you gain 20% increased life leeched per second, it will now heal your character for 120 health over 1 second.

The #% of maximum Life per second to maximum Life Leech rate modifier raises a character's leech cap, calculated as (Maximum Life * (0.20 + #% of maximum Life per second to maximum Life Leech rate) ). Normally a character with 5,000 life can only leech health at a maximum rate of 1,000 per second (5000 * 0.20 = 1000) regardless of how many leech instances they have and what rate they individually regain life. If that character gains 3% of maximum Life per second to maximum Life Leech rate, such as from the notable Vitality Void, they will be able to leech up to 1,150 life per second. (5000 * (0.20 + 0.03) = 1150)

There are a few notable ways for these factors to be altered besides the passive tree:[4]

Vorici's master modifier provides #% increased Life Leeched per second .

Leech duration

The leech recovery duration is how long in seconds a leech instance has to last to recover the entirety of the damage leeched.[5] It can be found by dividing the percent damage inflicted that is leeched by the leech recovery rate.

duration = damage dealt * % damage leeched / (max health * 0.02)

No modifiers to maximum leech rate affect the duration,[5] nor do modifiers to life recovery rate.[6] Note that the leeched damage is always rounded down to nearest integer, which can be noticeable for skills that do low amounts of damage quickly.

Combined Recovery Rate

The total leech recovery rate (accounting for all instances of leech) can be calculated by

total leech recovery rate = max life * 0.02 * instances of leech * (1 + increased leech per second)

where max life can also be the character's maximum mana for mana leech. Increased leech per second is the sum of all the #% increased (or reduced) Life/Mana Leeched per second modifiers.

This combined rate is subject to the leech cap, which is by default 20% of the character's maximum health. This maximum is increased by any #% of maximum Life/Mana per second to maximum Life/Mana Leech rate modifiers.

As such, each character only requires a certain number of leech instances before they will be recovering at their maximum rate. For a default character, this is 10 instances, but any increases or decreases from #% Life Leeched per second or #% of maximum Life per second to maximum Life Leech rate will change this number.[3] If a character has too many leech instances, the extra healing will be ignored. This maximum can be found with the below formula:

max instances = (0.2 + increased max leech rate) / (0.02 * (1 + increased leech per second))

Derivation of max instances Find the amount of instances that gives the maximum leech recovery rate: max recovery rate = recovery rate max life * instances * 0.02 * (1 + increased leech per second) = max instances * (0.2 + increased max leech rate) setting max instances to instances and solving yields the total amount of active leech instances allowed max instances = instances = (0.2 + increased max leech rate) / (0.02 * (1 + increased leech per second))

Immunity to leech

Players can become immune to being life/mana leeched from by enemies through allocating the Bloodless notable passive skill or by equipping the following unique items:

Cannot leech

The following unique items prevent the user from leeching life and/or mana.

Types of leech

There are several types of leech that specialize on certain types of skills. Some leech types only work for attacks, others only works with elemental damage or all sources of physical damage. If there is specialization it will be defined in the modifier.

Generally the leech modifiers follow this template:

#% of X Y Damage Z Leeched as Life/Mana

Where X can be:

Physical/Fire/Cold/Lightning/Elemental/Chaos

Y can be:

Attack/Spell

and Z can be:

Dealt with { Weapons

Note that if X, Y or Z are not specified it means that it applies to all those types.

Version history

Version Changes 2.0.0 Multiple leech effects now stack. A single hit against multiple targets grants multiple effects, as do multiple hits against a single target.

The speed at which you leech has been substantially reduced for both life and mana, with less of a reduction to mana leech rate, bringing it in-line with life leech rate. These now default to 2% of maximum life per second. It can be increased.

A maximum leech rate caps the rate at which you can leech. It's set to 20% of maximum life or mana per second.

Methods of improving leech, leech rate and increasing your maximum leech rate have been added to new clusters in the passive skill tree, primarily in the regions between the Marauder, Duelist and Ranger.

Some of the already existing clusters in this region that specialized in specific weapon types have also had leech elements added to them.

All existing values of leech have been substantially reduced, including values on existing items.

Some things such as Support Gems and Warlord's Mark have had their values brought in line with the other leech changes.

Previously, we had modifiers for "increased (or reduced) Life/Mana Leech rate". These did two things: They increased the amount of Life/Mana you're gaining per second for each leech effect and they reduced the duration of each leech effect, such that the total life/mana gained over the duration remained the same. All such modifiers have now been changed to "increased (or reduced) Life/Mana Leeched per second". This still increases the value of Life/Mana you're gaining per second for each leech effect, exactly as it did before. It no longer affects duration of the leech effects, meaning you'll gain more total life/mana from each one as a result.
