Heal Manipulation[]

Heal manipulation affects every ability that heals a unit. All sources of healing manipulation - whether incoming or outgoing - stack diminishingly, and have a higher and lower limit of 100% and -100% respectively.

Outgoing Healing Manipulation Sources
1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.

Lifesteal Manipulation[]

Lifesteal manipulation affects every source of Lifesteal. All sources of lifesteal manipulation - whether incoming or outgoing - stack diminishingly, and have a higher and lower limit of 100% and -100% respectively.

Lifesteal Manipulation neither affects Spell Lifesteal nor Spell Lifesteal Manipulation sources.

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.

Spell Lifesteal Manipulation[]

Spell Lifesteal manipulation affects every source of Spell Lifesteal. All sources of spell lifesteal manipulation - whether incoming or outgoing - stack diminishingly, and have a higher and lower limit of 100% and -100% respectively.

Spell Lifesteal Manipulation neither affects Lifesteal nor Lifesteal Manipulation sources.

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.

Health Regen Manipulation[]

Health regen manipulation affects all Health regeneration of a unit. All sources of health regen manipulation - whether incoming or outgoing - stack diminishingly, and have a higher and lower limit of 100% and -100% respectively.

Explicitly affects the health regeneration value of affected units.

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.

Stacking[]

Heal, health regeneration, lifesteal, and spell lifesteal amplifications stack diminishingly, and 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 multiplier for the total heal amount is defined as

Total Restoration Multiplier = 1 + (1 - (1 - Amplifications i)) - (1 - (1 - Reductions i))

This means the value can never reach -100% and 100%, unless a source grants exactly that or a greater value.

When there are no amplifications or no reductions, use 0 as a value for those cases.

Item Stacking[]

Example

Treant Protector minimap icon Treant Protector affected by Shiva's Guard icon Freezing Aura, Eye of Skadi icon Cold Attack, and has a Sange icon Sange in his inventory. What is his current total restoration manipulation multiplier?
Amplifications: Sange icon Sange: 0.2
Reductions: Shiva's Guard icon Freezing Aura: 0.25, Eye of Skadi icon Cold Attack: 0.4
Restoration Multiplier
= 1 + (1 - (1 - 0.2)) - (1 - (1 - 0.25) × (1 - 0.4))
= 0.65
Treant Protector minimap icon Treant Protector's restoration manipulator in this example would be reduced down to 65%, giving us a restoration multiplier of 0.65.

Health Freeze[]

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

Health Freeze Sources

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

Mana Restore Manipulation[]

Mana restore manipulation affects sources that restore a unit's mana. All sources of mana restore manipulation stack additively with each other.

Mana Restore Manipulation Sources
1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.

Mana Regen Manipulation[]

Mana regeneration manipulation affects explicitly the mana regeneration value of affected units. All sources of mana regen manipulation stack additively with each other.

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.
