Toughness

OverviewData

Toughness
Type	Combat Stats

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

In combat, the Toughness gauge is displayed above the HP gauge of enemies. If attacked by a Type that the enemy is weak to, the Toughness gauge will deplete. 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

In the enemy's next turn, they will recover from Weakness Break and regain a full Toughness gauge.

While an enemy's Toughness is active, all incoming DMG will be multiplied by 0.9. During Weakness Break, this effect is temporarily removed (essentially increasing DMG dealt by 11.11%).

Multi-Layered Toughness

Some enemies have multiple Toughness Bars. Break DMG will trigger every time a Toughness Bar is depleted, but the enemy will not enter the Weakness Broken state or suffer type-specific effects until the final Toughness Bar is depleted.

Exo-Toughness

Exo-Toughness is an unremovable status inflicted by certain effects. Enemies with Exo-Toughness will trigger Weakness Break when their initial Toughness is reduced to 0. Then, their temporary Toughness (displayed as purple bars) can continue to be reduced by any Type of attack regardless of their Weaknesses. When Exo-Toughness is reduced to 0, Weakness Break will be triggered again. Exo-Toughness will be removed after this occurs.

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 2.5, 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.

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:

${\text{Max Toughness Multiplier}}=0.5+{\frac {{\text{Max Toughness}}_{\text{Target}}}{40}}$

Break Properties

Type	Break Base DMG	Applied Debuff
Physical	$2 \times \text{Level Multiplier} \times \text{Max Toughness Multiplier}_\text{Target}$	Bleed

Damage Formula

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

$\begin{align} \text{DMG} ={} & \text{Base DMG} \times (1 + \text{Break Effect}) \\ & \times \text{DEF Multiplier}_\text{Target} \times \text{RES Multiplier}_\text{Target} \times \text{Vulnerability Multiplier}_\text{Target} \\ & \times \text{Broken Multiplier}_\text{Target} \end{align}$

Where:

$\text{DEF Multiplier} = \frac{\text{Level}_\text{Attacker} + 20}{(\text{Level}_\text{Enemy} + 20) \times (1 - \% \text{DEF Reduction} - \% \text{DEF Ignore}) + \text{Level}_\text{Attacker} + 20}$

$\text{RES Multiplier} = 1 - (\text{RES}_\text{Target} - \text{RES PEN}_\text{Attacker})$

${\text{Vulnerability Multiplier}}=1+{\text{Type Vulnerability}}+{\text{All Type Vulnerability}}+{\text{DoT Vulnerability}}$

$\text{Broken Multiplier} = \begin{cases} 0.9 & \text{if enemy has Toughness (affects Break DMG)}\\ 1.0 & \text{if enemy Toughness is broken}\\ \end{cases}$

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:

${\begin{aligned}{\text{Super Break DMG}}={}&{\text{Level Multiplier}}\times {\frac {\text{Toughness Reduction}}{\text{10}}}\\&\times (1+{\text{Break Effect}})\times (1+{\text{Super Break DMG Increase}})\\&\times {\text{DEF Multiplier}}_{\text{Target}}\times {\text{RES Multiplier}}_{\text{Target}}\times {\text{Vulnerability Multiplier}}_{\text{Target}}\end{aligned}}$

Level Multiplier is determined by the attacker's level (Level 81 to Level 95 stats are enemy-exclusive when their Weakness is Broken due to their own effect):
