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

In The Awakening expansion the leech mechanics were changed with the goal to make it harder to leech against a single enemy. Earlier the leech recovered at a constant rate, this method do not take into account how many enemies that were hit by the skill. The leech mechanic was therefore changed so that a new leech instance was created per hit. These instances can stack meaning a single hit against multiple targets will grant multiple instances, as will multiple hits against a single target.[3]

Leech is calculated by taking a percent of each hit done according to the Attack Damage Leeched as Life (or Mana) stat then healing the character up to that amount according to the leech recovery rate. The default leech recovery rate is 2% of the character's max health per second, which can be increased by #% increased (or reduced) Life/Mana Leeched per second modifiers. There is a maximum amount of leech recovery rate per second which is by default 20%, this can be increased by #% of maximum Life/Mana per second to maximum Life/Mana Leech rate modifiers.[4]

Each hit against each target creates a new instance of leech which will all heal the character simultaneously until the maximum leech recovery rate per second is reached.[5]

Recovery rate

The total leech recovery rate (accounting for all instances of leech) is given by

total leech recovery rate = max life * instances of leech * 0.02 * (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.

There is an upper limit of the leech recovery rate which is defined as 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.

The total amount of active leech instances allowed that will not exceed the maximum recovery rate is

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))

Leech duration

The leech recovery duration is how long in seconds a leech instance has to last to recover the entirely of its life pool.[6] It can be found by dividing the percent damage inflicted that is leeched by the leech recovery rate.

duration = damage inflicted * % attack damage leeched / (max health * 0.02 * (1 + increased leech per second))

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.

Modifiers

Modifiers that alters the leech recovery rate increases the value of Life/Mana you're gaining per second for each leech effect. However, it does not affect the duration, tdur, of the leech effects, meaning that more total life/mana will be gained from each leech instance as a result.[3][6] This also implies that by increasing the Life/Mana Leeched per seconds gives a larger total of life leeched compared to Vaal Pact.

There are only a couple of ways for these factors to be altered, besides the passive tree:[3][7]

several enemies can be hit at once. The leech rate will vary considerably depending on how many enemies are hit.

The character used in the following examples have the following stats:

p = 5000 maximum life.
d = 1000 damage taken by the enemy.
l = 1 % life leech.
1 enemy hit
n = 1 leech instance/enemy.
m = 0% increased Life Leeched per second.
mmax = 0% of maximum Life per second to maximum Life Leech rate.

The recovery rate is:

r = n * p * q * (1 + m) = 1 * 5000 * 0.02 * (1 + 0) = 100 HP/sec

Make sure that the recovery rate doesn't exceed the maximum recovery rate which is

rmax = p * (qmax + mmax) = 5000 * (0.2 + 0) = 1000 HP/sec

The limit has not been exceeded, meaning that no substitution is necessary.

The time it takes to recover the total amount of life leeched is

tdur = d * l / (p * q) = 1000 * 0.01 / (5000 * 0.02) = 0.1 seconds

which gives the total life leeched

HP(tdur) = r * tdur = 100 * 0.1 = 10 Life
5 enemies hit at once
n = 5 leech instances/enemies.
m = 0% increased Life Leeched per second.
mmax = 0% of maximum Life per second to maximum Life Leech rate.

The recovery rate is:

r = n * p * q * (1 + m) = 5 * 5000 * 0.02 * (1 + 0) = 500 HP/sec

Make sure that the recovery rate doesn't exceed the maximum recovery rate which is

rmax = p * (qmax + mmax) = 5000 * (0.2 + 0) = 1000 HP/sec

The limit has not been exceeded, meaning that no substitution is necessary.

The time it takes to recover the total amount of life leeched is

tdur = d * l / (p * q) = 1000 * 0.01 / (5000 * 0.02) = 0.1 seconds

which gives the total life leeched

HP(tdur) = r * tdur = 500 * 0.1 = 50 Life
11 enemies hit at once
n = 11 leech instances/enemies.
m = 0% increased Life Leeched per second.
mmax = 0% of maximum Life per second to maximum Life Leech rate.

The recovery rate is:

r = n * p * q * (1 + m) = 11 * 5000 * 0.02 * (1 + 0) = 1100 HP/sec

Make sure that the recovery rate doesn't exceed the maximum recovery rate which is

rmax = p * (qmax + mmax) = 5000 * (0.2 + 0) = 1000 HP/sec

The limit has been exceeded, therefore the recovery rate needs to be changed to r = 1000 HP/sec.

The time it takes to recover the total amount of life leeched is

tdur = d * l / (p * q) = 1000 * 0.01 / (5000 * 0.2) = 0.1 seconds

which gives the total life leeched

HP(tdur) = r * tdur = 1000 * 0.1 = 100 Life

Marauder dual strike
 
For example, let's take a marauder with dual strike skill.
p= 5577 life total
L= 3.2% base phys leech (gear and passives)
m= 93% Inc. leech per second
Mmax+13% of max life per second to max life leech rate 
d= 1400-2500 single attack physical damage (I used MINIMUM main hand damage)
n= number of enemies (1 for this example)
r= recovery rate
Rmax= cap for recovery rate
Tdur= Leech duration
APS= attacks per second

(Variables left in for ease of use)

Recovery rate
r215.27= p5577 * n1 * q0.02 * (1 + m0.93)

Recovery rate max cap
Rmax 1187.90 = p5577 * (Qmax0.2 + Mmax 0.013)

Leech duration
MINIMUM Tdur 0.40 = d1400 * L0.032 / (p5577 * 0.02)
MAXIMUM Tdur 0.72 = d2500 * L0.032 / (p5577 * 0.02)

Total Leech Figures
86.46 leech per hit per per enemy MINIMUM = r215.27 * Tdur0.40
154.4 leech per hit per per enemy MAXIMUM= r215.27 * Tdur0.72 

911.33 to 1627.376 leeched per second per enemy= APS10.54 x 86.464 and then x 154.4 for min/max leech
4556.65 to 8136.88 leeched per 5 enemies per second
9113.3 to 16273.76 leeched per 10 enemies per second

Types of Leech

There's several types of leech that specializes on certain types of skills. Some leech types only works 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:

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