Weakness Break

HP and Toughness answer different questions

An enemy’s HP tells you how close it is to defeat. Its Toughness bar tells you how close it is to a Weakness Break. Reducing one does not necessarily reduce the other. An attack can deal HP damage while leaving Toughness untouched.

The Element icons above an enemy show its weaknesses. Under the normal rules, an attack reduces Toughness when its Element matches one of those icons. Match the enemy you are targeting, rather than assuming every enemy on the field has the same weaknesses.

A Character’s Element and their damage pattern are listed in the Characters directory and Kit tabs. Path and Element are different labels: the Path alone does not tell you which weakness an attack can exploit.

Use the right attack, not just a bigger damage number

Each attack has its own Toughness-reduction behavior. A larger HP-damage number does not automatically remove more Toughness. Nor does a flashy multi-hit animation prove that the move is a stronger breaker. Read the ability and observe the bar it actually removes.

Some kits change the matching rule. They can add a weakness, reduce Toughness while ignoring an Element mismatch, or do both under particular conditions. Firefly’s enhanced Skill and Fugue’s abilities are examples of explicitly described exceptions. Their rules do not grant the same behavior to every attack in the team.

Enemies can also protect or lock their Toughness during a mechanic. If the bar is not moving, check the target’s state and the attack’s rules before changing your entire build. More Break Effect is not a universal answer to an inaccessible bar.

The last Toughness hit creates the Break

When Toughness reaches zero, the enemy enters Weakness Break. The triggering attack causes an additional Break-damage instance, delays the enemy’s action and applies the Break effect associated with that attack’s Element, subject to the target’s relevant resistances or immunities.

The Character who empties the bar is the breaker. Their relevant stats and level matter for that Break; the game does not pool the team’s Break Effect into one number. A teammate can help remove most of the bar while another delivers the final reduction.

Weakness Break is a window, not a permanent removal of Toughness. Enemies normally recover the bar when they reach their recovery action. Freeze, additional delay and specific abilities can change how that plays out. Watch the action order rather than assuming every broken enemy stays disabled for the same number of your turns.

The breaking Element changes the result

All seven Elements can trigger Weakness Break. The effect below comes from the Element of the attack that finishes the bar, not the order of icons above the enemy. Damage over time means damage applied later by a status, rather than only by the initial hit.

Break Effect and Break Efficiency do different jobs

Break Effect improves damage associated with Break and some Element-specific Break effects. It does not, by itself, make an ordinary attack take a larger chunk out of the Toughness bar. The standard Break-damage calculation also differs from normal attack damage: stacking ATK or CRIT is not a substitute for building Break damage.

Weakness Break Efficiency increases Toughness reduction. It appears in specific abilities, such as Ruan Mei’s Skill. It helps reach the Break sooner; it is not simply another name for the Break Effect stat on a Relic.

Imagine two versions of the same eligible attack, against the same enemy. Raising only Break Effect does not move the initial Toughness bar farther. An applicable efficiency increase does. If that attack triggers a Break, its Break Effect then matters to the resulting effect. Keep the bar-removal step separate from the damage step.

This distinction makes Relic stat choices easier to understand. A stat is useful because it supports the Character’s actual job, not because its name contains the mechanic the team uses.

Super Break needs an effect that enables it

Super Break is separate from the Break triggered when Toughness first reaches zero. An enabling ability converts an attack’s Toughness reduction into damage against an already Weakness Broken target. Harmony Trailblazer’s Backup Dancer effect is one example; other Characters provide their own versions and conditions.

Simply equipping Break Effect does not switch Super Break on. Check that the enabling effect is active, the target meets its condition and the attack has qualifying Toughness reduction. An enemy being broken does not automatically remove Element restrictions from every move.

Super Break can reward both Break Effect and greater qualifying Toughness reduction. That connects the two jobs from the previous section, but does not make them identical. The exact conversion belongs to the enabling kit, not a single universal percentage.

You may also encounter abilities that trigger Break damage again or add another reducible layer, such as Fugue’s Cloudflame Luster. Do not treat every later Break-like number as the same mechanic. The ability text tells you what is being triggered.

Plan for the window you are creating

For a general team, breaking a dangerous enemy can create breathing room while you continue dealing HP damage. A Break-focused team also needs to exploit the window before recovery. Its plan is incomplete if the enemy breaks just as the team runs out of actions or resources.

• Before the Break: identify which moves can reduce this target’s Toughness and whether a lock must be cleared.
• At the Break: consider who lands the final hit when the breaker’s contribution matters.
• During the window: keep the relevant buffs or Super Break enabler active and the necessary Skills available.
• At recovery: reassess the bar and action order instead of repeating a sequence blindly.

These are planning questions, not a reason to delay every available attack. Survival, target priority and the encounter’s own mechanics can matter more than arranging a perfect final hit.

Put it into practice

In your next fight, pick one target and watch its Toughness separately from its HP. Notice which action empties the bar, the status it applies and when the enemy recovers. Then check whether your team can actually use that window.

Skill Points and Energy explains the resources behind those actions. Character Kit tabs carry the exact rules for individual Break enablers. Once the system is clear, Endgame Insights provides encounter context without replacing those rules with a universal team recommendation.
