Status Resistance is an attribute of a hero that reduces the duration of most status debuffs. By default, every unit has a base status resistance of 0.


Definition[edit]

Status resistance generally only affects modifiers placed by enemies and not ones placed by allies.

There are some technical exceptions and it does not affect every modifiers. When a unit's status resistance is modified, the new debuff duration value is only applied to debuffs applied after the modification, it does not update the duration of already placed debuffs or the current debuff instance.

Mechanics Status Resistance Affecting Component Examples
Base Status Resistance

Auras
  • Do not have a duration to reduce.
  • The aura linger duration is not affected.
Natural Order
Effect Delay
  • Not reduced if the purpose of a temporary modifier is to delay another ability effect/component.
Reincarnation
Undispellable.
Permanent Modifiers
  • Do not have a duration to reduce.
Brain Drain
Damage Over Time
  • Damage over time is generally not reduced.
  • Total damage dealt over time stays the same.
  • Modifiers with damage over time have the damage tick interval adapted to the reduced duration.

  • Slow Resistance sources manipulate movement speed slow duration and are not affected by status resistance sources.

%Bonus/Reductions
  • Status Resistance bonus or reduction sources from abilities, items, talents.
  • Percentage-based values stack independently of each other.

Equations[edit]

Status resistance bonus from Sange-based items do not stack with each other, the higher status resistance value takes priority.

Total Status Resistance = 1 - Status Resistance Multiplier

Status Resistance Multiplier = (1 - Base Status Resistance) × (1 - MAX( Sange-%based)) × <math>\prod_{i=1}^{n}</math>(1 - Status Resistance Modifiers i )

Total Debuff Duration = Original Duration × Status Resistance Multiplier × <math>\prod_{i=1}^{n}</math>(1 - Debuff Duration Modifiers i )

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.

Only certain status resistance granting sources have stacking restrictions and are separated into 3 groups. The status resistance bonuses from Sange-based items do not stack with each other, with the one with a higher value taking priority. However, other sources from different groups stack independently, but still multiplicatively of each other.

  • Group 1: Sange-based items.
  • Group 2: Stack-based bonus/reductions stack additively of itself and multiplicatively with other sources.
  • Group 3: Miscellaneous — Sources that do not belong to any of the first 2 groups fully stack with each other, with multiple of themselves, and with other item bonuses.
  • Group 4: Outgoing Debuff Duration Amp

Examples[edit]

Example 1a
Status Resistance Bonus and Status Resistance Multiplier
Spirit Breaker has Sange and Yasha equipped with level 2 Bulldoze active. What is his current status resistance?
Base unit status resistance: 0
Bonus status resistance: Bulldoze 0.5, Sange and Yasha 0.15
Total Status Resistance
= 1 - (1 - 0) * (1 - 0.5) * (1 - 0.15)
= 0.575
Spirit Breaker currently has 57.5% status resistance in this example, and all debuff duration applied on him will now be multiplied by 0.425.
Example 1b
Debuff Duration and Status Resistance Multiplier
How long would a 3-second Debuff debuff duration be on Spirit Breaker from the previous example?
Total Debuff Duration
= 3 * 0.425
= 1.28
The Debuff debuff duration will affect Spirit Breaker for a duration of 1.28s instead of 3s in this example.
Example 2
Calculating Actual or Total Debuff Duration
Spirit Breaker from the previous example now has both Sange and Yasha.
He is currently affected by a 0.1-status resistance reduction.
The enemy Rubick now has Timeless Relic equipped. How long would a 3-second Debuff debuff duration be on Spirit Breaker now?
Base unit status resistance: 0
Bonus status resistance: Sange and Yasha (15/100)
Status resistance reduction: -0.1
Total Status Resistance:
= 1 - (1 - 0) * (1 - 0.15) * (1 - -0.1)
= 0.065
Spirit Breaker currently has 6.5% status resistance in this example, and all debuff duration applied on him will now be multiplied by 0.935, before other debuff duration amplification applied.

Modifying Status Resistance[edit]

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

Increasing Sources[edit]

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

Items[edit]

These items have a bonus status resistance to the hero who has them equipped.

Bonus Status Resistance Items
Item Value Item Cost Cost/Value Point
Sange and Yasha 15% 4200 Gold 280 Gold
Titanic Enchantment 0.67% N/A N/A
Values do not include portions from actives or auras.

Debuff Duration Manipulation[edit]

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

Dynamic Tick Intervals[edit]

Several abilities that do something in intervals have their intervals adapt to a changed duration. This includes duration changes caused by status resistance or debuff duration amplification.

The following abilities have dynamic tick intervals

Other Interactions[edit]

  • Reduces duration normally when cast on enemy. When transfered to another enemy via an attack command, the invulnerability modifier always uses the base duration and is then reduced by the new target's status resistance, while the Nightmare modifier copies the previous target's reduced duration, and then gets further reduced by the new target's status resistance.
  • Reduces duration of all debuffs it can place, on primary and secondary targets. On secondary targets, the knockback speed adapts to the reduced duration, so that the knockback distance is kept the same.
  • Reduces the duration normally. When the target has more than 75% status resistance, it no longer gets automatically returned upon expiring.
  • Reduces the duration. The slow tick rate does not adapt to the reduced duration.
  • Reduces the debuff duration on the target. The debuff on the caster does not adapt.This is an old ability.
  • When applied by attacks, only reduces the slow duration after the explosion. Does not affect the initial debuff. When applied with Burrowstrike, does reduce the initial debuff duration, on top of reducing the slow duration.
  • Self buff duration is reduced along with enemy debuff duration.
  • Self buff duration is reduced along with enemy debuff duration.
  • Reduces the debuff duration on the target. The penalties on the caster do not adapt.
  • Reduces trail creating debuff duration. When directly targeted, may reduce slow debuff duration. When not directly targeted, does not affect slow debuff.
  • When activated via the sub-spell on the caster or via Psionic Projection, only reduces the slow value. When activated via the sub-spell on the trap itself, reduces slow value and duration, and increases damage per tick.
