Status resistance is an attribute of a hero that reduces the duration of most status debuffs and the slow values of slows. By default, every unit has a base status resistance of zero.

Mechanics[edit]

Status resistance affects all kind of debuffs, but generally only affects modifiers placed by enemies, and not ones placed by allies. Status resistance does not affect all modifiers, there are some exceptions, mainly for technical reasons. When a unit's status resistance is modified, the new value is only applied to debuffs placed after the modification, meaning already placed debuffs are unaffected.

Aura modifiers and other permanent modifiers are usually not reduced, since they have no duration to reduce. Although auras have a linger duration, that duration is not reduced either.
If a permanent modifier slows, its slow value may get reduced, though this is inconsistent between such modifiers.
If a temporary modifier deals damage over time, its duration is not reduced. If the modifier applies a slow, the slow value is reduced instead.
If a temporary damage over time modifier applies a form of disable that is not a slow, its duration does get reduced, but its damage tick interval gets adapted to the reduced duration, so that the total damage stays the same.
If an essential part of a temporary modifier's purpose is delaying another effect or showing another effect's delay, it is not reduced.
If a spell affects secondary targets, and the secondary target's duration is based on the primary target, the duration on it may get reduced as well, based on the primary target's status resistance. There are some exceptions to this though.
Negative status resistance works exactly the same as positive status resistance. It is the same mechanic, with merely negative values.

Stacking[edit]

All sources of status resistance stack multiplicatively. This means a unit's status resistance value changes less the higher its status resistance is, and more the lower it is. This prevents a unit from reaching 100% status resistance by stacking different sources up.

Status resistance bonus from Sange-based items, such as Sange and Yasha, Kaya and Sange and Heaven's Halberd do not stack with each other.

Total status resistance is defined as

\sum _{StatusResistance}=1-\displaystyle \prod _{i=1}^{n}(1-S_{i})

With S being the index of status resistance sources.

\sum _{StatusResistance}=1-{\Big (}(1-StatusResistance_{1})\times (1-StatusResistance_{2})\times \dots {\Big )}

Example 1

Spirit Breaker with an activated Level 2

Bulldoze and

Sange and Yasha. What is his current status resistance?

Status resistance: Level 2

Bulldoze: 0.46,

Sange and Yasha:0.25

\sum _{StatusResistance}=1-{\Big (}(1-0.46)\times (1-0.25){\Big )}=0.595

Spirit Breaker currently has 59.5% status resistance in this example.

Example 2

An

Enraged

Ursa has

Sange and Yasha and is affected by

Heavenly Grace. What is his current status resistance?

Status resistance:

Sange and Yasha: 0.25,

Enrage: 0.5,

Heavenly Grace: 0.5

\sum _{StatusResistance}=1-{\Big (}(1-0.25)\times (1-0.5)\times (1-0.5){\Big )}=0.8125

Ursa currently has 81.25% status resistance in this example.

Debuff duration and debuff duration manipulation[edit]

Similar to status resistance, which affects incoming debuffs' durations, debuff duration manipulation affects outgoing durations instead. Any ability whose duration would be reduced by status resistance will have its duration increased by debuff duration increases.

Actual status debuff durations after status resistance is defined as

{\text{ActualDebuffDuration}}=OriginalDuration\times (1-\Sigma StatusResistance)\times \displaystyle \prod _{i=1}^{n}(1+a_{i})

With a being the index of debuff duration manipulation.

Example 1

Spirit Breaker from the previous example with the same conditions is affected by Level 4

Telekinesis, how long would the

Telekinesis lift duration be after status resistance?

Status resistance: Level 2

Bulldoze: 0.46,

Sange and Yasha: 0.25

Debuff duration: Level 4

Telekinesis lift: 2

{\text{ActualDebuffDuration}}=2*(1-0.595)*(1+0)=0.81

A Level 4

Telekinesis will affect

Spirit Breaker for a duration of 0.81 instead of 2 in this example.

Example 2

Spirit Breaker from the previous example with the same conditions is affected by Level 4

Telekinesis with

Timeless Relic. How long would the

Telekinesis lift duration be after status resistance?

Status resistance: Level 2

Bulldoze: 0.46,

Sange and Yasha: 0.25

Debuff duration: Level 4

Telekinesis lift: 2

Debuff duration manipulation:

Timeless Relic: 0.25

{\text{ActualDebuffDuration}}=2*(1-0.595)*(1+0.25)=1.0125

A Level 4

Telekinesis will affect

Spirit Breaker for a duration of 1.0125 (after status resistance reductions and debuff duration manipulation) instead of 2 in this example.

Sources of debuff duration manipulation

Rubick - Spell Steal
Debuff duration amplification: 10%/20%/30%
Timeless Relic
Debuff duration amplification: 25%

Modifying status resistance[edit]

Several abilites and items have abilities that grant or reduce status resistance.
