Restoration manipulation
Restoration manipulation refers to any form of amplification and reduction applied to health restoration (also known as heals), lifesteal, health regeneration, mana restoration, and mana regeneration.

Heal manipulation[edit]
Heal manipulation affects every ability that heals a unit. A list of healing abilities can be found here.
All sources of heal manipulation whether incoming or outgoing stack diminishingly with each other. Heal manipulation has a lower limit of -100%.
The following abilities provide heal manipulation

Aura, affects all nearby allies.
Heal reduction: 40%
Affects the attacked enemy.
Heal amplification: 35%
Amplifies all healing the item owner provides.
Heal amplification: 75%

Affects the attacked enemy.
Health regen reduction: 35%
Affects the attacked enemy.
Stacking[edit]
Heal, health regen, 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.
This leads to the following formula with "a" being the index of any amplification, "r" being the index of any reduction. There cannot be no amplification or no reduction, use zero in those cases:
Total manipulation = (1 − (1 − first amplification) × (1 − second amplification) × ...) - (1 - (1 − first reduction) × (1 − second reduction) × ...))
= - Πa(1 - amplificationa) + Πr(1 - reductionr)
To get the multiplier for the actual heal amount:
Manipulation multiplier = 1 + Total manipulation
Example:
- Treant Protector affected by Nature's Guise, Divine Favor, Freezing Aura, and Cold Attack has the following total heal manipulation
(1 − (1 − 0.18) * (1 − 0.4)) - (1 - (1 − 0.25) * (1 − 0.4)) = -4.2% heal manipulation- This means in this example, heals would be reduced down to 95.8%, giving us a multiplier of 0.958.
Health freeze[edit]
A unit's health can also be frozen, so that no heals, lifesteal, or regeneration can increase it.
The following abilities freeze health
Duration: 10/11/12
Mana restore manipulation[edit]
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
- Mana restore amplification: 75%
Affects the caster.
Mana regen manipulation[edit]
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
Mana regen amplification: 100%
Affects the item owner.- Mana regen amplification: 75%
Affects the caster. - Mana regen amplification: 24%
Affects the item owner. - Mana regen amplification: 30%
