Stacking

Heal, health regeneration, lifesteal, and spell lifesteal amplifications stack diminishingly, so do reductions. However, amplifications and reductions are calculated separately, and then the sum of reductions gets subtracted from the sum of the amplifications.

The total restoration manipulation is defined as

$\sum _{RestorationManipulator}={\Big (}1-\displaystyle \prod _{i=1}^{n}(1-a_{i}){\Big )}-{\Big (}1-\displaystyle \prod _{i=1}^{n}(1-r_{i}){\Big )}$

With a being the index of any amplification, r being the index of any reduction. There cannot be no amplification or no reduction, use 0 as a value in those cases.

${\text{RestorationManipulator}}={\Big (}1-(1-Amplification_{1})\times (1-Amplification_{2})\times \dots {\Big )}-{\Big (}1-(1-Reduction_{1})\times (1-Reduction_{2})\times \dots {\Big )}$

To get the multiplier for the actual heal amount

${\text{ManipulationMultiplier}}=1+RestorationManipulator$

Example 1

Treant Protector affected by Nature's Guise, Level 4 Divine Favor, Freezing Aura, and Cold Attack. What is his current total restoration manipulation multiplier?

Amplifications: Nature's Guise: 0.4, Divine Favor: 0.18

Reductions: Freezing Aura: 0.25, Cold Attack: 0.4

$\sum _{RestorationManipulator}={\Big (}1-(1-0.18)\times (1-0.4){\Big )}-{\Big (}1-(1-0.25)\times (1-0.4){\Big )}=-4.2\%$

Treant Protector's restoration manipulator in this example would be reduced down to 95.8%, giving us a multiplier of 0.958.

Health Freeze

A unit's health can also be frozen, so that no heals, lifesteal, or regeneration can increase it.

The following abilities freeze health:

• Ancient Apparition - Ice Blast
  
  Duration: 10/11/12
  The debuff prevents the current health of affected units from increasing.
• Oracle - False Promise
  
  Duration: 8/9/10 ( 9.5/10.5/11.5)
  Also negates all damage taken for the duration.

However, Health Freeze does not prevent the following abilities from increasing the hero's health:

• Lone Druid – True Form
• Phoenix – Supernova
• Shadow Demon – Soul Catcher
• Terrorblade – Sunder
• Timbersaw – Whirling Death
• Undying – Decay
• Weaver – Time Lapse
• Essence Ring – Life Essence

Mana Restore Manipulation

Mana restore manipulation affects every ability that restores a unit's mana. A list of restoring abilities can be found here.

All sources of mana restore manipulation stack additively with each other.

The following abilities provide mana restore manipulation

• Necrophos - Ghost Shroud
  
  Mana Restore Amplification: 75%
  Affects the caster.

Mana Regen Manipulation

Mana regen manipulation affects explicitly the mana regen value of affected units.

All sources of mana regen manipulation stack additively with each other.

The following abilities provide mana regen manipulation:

• Bloodstone
  
  Mana Regen Amplification: 100%
  Affects the item owner.
• Necrophos - Ghost Shroud
  
  Self Restoration Amplification: 75%
  Affects the caster.
• Kaya
  
  Mana Regen Amplification: 50%
  Affects the item owner.
