OverviewData

Toughness is an enemy-only stat in Honkai: Star Rail.

In combat, the Toughness gauge is displayed above the HP gauge of enemies. It can be reduced by attacks of a Type that the enemy is weak to. Once fully depleted, the enemy will suffer a Weakness Break which has the following effects:

  • Deals an instance of Break DMG
  • Delays the enemy's action by 25%
  • Has a 150% base chance to apply a debuff corresponding to the Type used to inflict Weakness Break
  • Enters the Weakness Broken state

In the enemy's next turn, they will recover from the Weakness Broken state and fully restores their Toughness gauge.

As long as the enemy is not Weakness Broken, all incoming DMG will be multiplied by 0.9, including the Break DMG from Toughness depletion.

Dealing Break DMG solely is not considered an attack.

Multi-Layered Toughness

Some enemies have multiple Toughness Bars. Fully depleting any Toughness Bar before the final one will only deal Break DMG without any other Weakness Break effects (action delay, Type-specific debuffs, entering the Weakness Broken state).

Exo-Toughness

Exo-Toughness

A purple Exo-Toughness behind the initial Toughness.

Exo-Toughness is an additional Toughness bar applied by certain effects, which is displayed behind the initial white Toughness. The initial Toughness needs to be depleted first (which triggers Weakness Break effects) before the Exo-Toughness can be reduced. Then, the Exo-Toughness can be reduced with any Type of attack regardless of Weaknesses, triggering Weakness Break again if depleted, which is equal to when depleting the original Toughness. Like the original Toughness, the Exo-Toughness can only be depleted once before recovering from Weakness Break.

Toughness Value and Reduction

Different enemies have varying amounts of Toughness. The base Toughness value of most enemies is a multiple of 10, with the exception of some enemies with modified Toughness value in a certain phase. Sometimes, 10 Toughness Reduction on display is also referred to as 1 Toughness Unit.

Different character skills will also deal varying amounts of Toughness Reduction. Currently, characters may deal 2, 2.5, 3.333..., 5, 10, 15, 20, 30 or 40 Toughness Reduction with their attacks.

Attacking an enemy in the overworld will deal 10 Toughness Reduction to all enemies weak to that attack's type upon entering battle. Certain Techniques can attack the enemy in the overworld and deal 20 Toughness Reduction to all enemies weak to that attack's type upon entering battle.

Some enemies have the ability to make themselves immune to Toughness Reduction.

Toughness Reduction Formula

For calculating Toughness Reduction:

Where:

Currently, Weakness Break Efficiency has a cap of 300%.

Weakness Break

When enemy targets' Toughness is reduced to 0, they will enter the Weakness Break State, which delays their actions.

Type-Specific Effects

Break DMG increases with higher Break Effect, higher target max Toughness, and higher character levels.
Break DMG cannot CRIT Hit and is not affected by DMG Boost effects.

Depending on the Type that caused the Weakness Break, the Base DMG of the Break DMG and the debuff applied will differ:

Break Properties
Type Break Base DMG Applied Debuff
Physical Physical Bleed
Fire Fire Burn
Ice Ice Freeze
Lightning Lightning Shock
Wind Wind Wind Shear
Quantum Quantum Entanglement
Imaginary Imaginary Imprisonment
Debuff Properties
Debuff Debuff Base DMG Turns Additional Effects Is DoT
Icon Bleed Bleed Normal:

Icon Shock Shock 2
Icon Wind Shear Wind Shear 2 Applies 1 stack to Normal, 3 stacks to Elite/Boss Enemies (Max 5 Stacks)
Icon Entanglement Entanglement 1 Delays action by

Icon Imprisonment Imprisonment 1 Delays action by
Reduces the speed of the Imprisoned target by 10%

Damage Formula

For calculating Break DMG, DoT, and Delayed DMG caused by Weakness Breaks:

Where:

Break-related DMG is not affected by Weaken.

Break DMG Increase includes effects such as Fugue's Eidolon .

Super Break DMG

Super Break DMG increases with higher Break Effect, higher Toughness Reduction of the attack, and higher character levels.
Super Break DMG cannot CRIT Hit and is not affected by DMG Boost effects.
Super Break DMG is also considered Break DMG.

Super Break DMG is a special variation of Break DMG dealt by certain abilities. Super Break DMG is dealt only when enemy targets are attacked in the Weakness Broken state, and the Toughness Reduction of hits dealt in the Weakness Broken state will be converted into 1 instance of Super Break DMG.

For calculating Super Break DMG:

Super Break DMG Increase includes effects such as Trailblazer (Harmony)'s Bonus Ability .
