Injuries#

From the in-game glossary: "Lowers an attribute until it heals. Small chance of occurring when knocked out."

Injuries are rolled only on knockouts, never on staggers. This page covers when that roll happens, the two chance formulas (one for Rogue runs, one for other modes), the four injury types and their stat penalties, healing time, and what prevents injuries.

1. When an injury roll happens#

Forward.Knockout decides between a forced injury and a normal roll.

A forced injury happens if any of these is true. It skips the chance roll entirely (AddRandomInjury).

Otherwise a normal roll (InjurySystem.TryInjuryAttempt) happens only when:

• there is an attacker, and
• the knockout type is PuckCollision, Stick, Bodycheck or Ability.

Explosion and Helmet knockouts never roll.

When an injury happens:

• The knockout lasts +8 s longer (InjuryConfig.knockoutTime).
• Double Yolk (DoubleIncision) adds 1 extra injury at level 1, or 2 at level 2.
• Egg Shell Hands also targets the hands.

No roll happens at all if injuries are disabled for the match (AreInjuriesDisabledInMatch) or the victim has no injury types left to receive (GetPossibleInjuries is empty).

2. Injury chance in Rogue runs (pacing system)#

In Rogue mode (GameType.Rogue), the chance is not based on stats. InjuryPacingService.ShouldNaturalInjuryOccur uses a "due" counter instead:

due      = clamp01(KOsSinceLastNaturalInjury / KOsPerInjury) × baseInjuryRate
if this team already had a natural injury this game:  due ×= softCap
chance   = due × powerupMultiplier
injured if chance ≥ Random.Range(0,1)

Every knockout counts toward the KO counters, whether or not it causes an injury. A natural injury resets that team's "since last" counter to 0 (RecordNaturalInjury).

Each KO adds to these counters: playerKnockoutsThisGame, ThisAct and SinceLastInjuryThisAct for the player team; cpuKnockoutsThisGame and SinceLastInjuryThisGame for CPU teams. So the player's counter runs across a whole act, while the CPU's resets every game.

powerupMultiplier is the product of three factors:

Source: InjurySystem::HandleInjury (rogue branch), InjuryPacingService::ShouldNaturalInjuryOccur, RecordNaturalInjury, IsPlayerHardCapReached, InjurySystem::GetEnragedInjuryMultiplier, GetFragileRelicMultiplier, InjuryConfig asset.

3. Injury chance outside Rogue (Quick Game and similar)#

InjurySystem.CalculateInjuryChance is used instead:

base   = sameTeam ? sameTeamInjuryChance (0.005) : newInjuryChance (0.09)
base  += victim.injuryCounter          // "pity" counter, see below
chance = base × prevInjuryMultiplier × powerupMultiplier

Pity counter. Every failed roll adds +0.02 to the victim's ForwardData.injuryCounter, up to a maximum of 0.25. A successful injury resets it to 0.

prevInjuryMultiplier depends on how many injuries the victim already has:

In this mode, a successful roll grants the victim the Fragile talent and fires an event. It does not add a pacing-tracked injury (how this shows up on screen is inferred).

Source: InjurySystem::CalculateInjuryChance, HandleInjury (non-rogue branch).

4. Fragile talent#

Fragile (Rogue.Powerups.Chaos.FragileTalent) reads: "10% chance of an injury each time this skater is knocked flat on the ice. Bench for a game or see the Nurse to recover."

If the victim has this talent, HandleFragileInjury replaces the normal roll and bypasses pacing and caps:

chance = fragileBaseChance (0.10) × SpikedArmor × EnragedInjury × FragileRelic

The pity counter still moves: +0.02 on a miss (max 0.25), reset on a hit.

5. Injury types and their stat penalties#

InjuryType has four values. ForwardStats.GetStatAfterInjuryCheck applies the penalty whenever the stat is read:

The Shoulder penalty also feeds the bodycheck score, so injured skaters lose checks badly (see bodychecking).

Masochist (SadoMaso) removes the stat penalty: "Injuries give +10 (lvl 1) / +20 (lvl 2) attribute instead". It also makes injuries last +2 games longer (SadoMasoInjuryDurationBonusGames = 2, GetAdjustedHealingTime).

6. Duration and healing#

Injury length is counted in games. It is rolled when the injury is created:

After every game (OnGameFinished → UpdateInjuryHealingTime), each injury's HealingTime drops by 1. At 0 the injury is healed and shows on the "just healed" list.

Nurse. The Nurse map event can heal every injury (HealAllInjuries), or "cripple" a skater for 1–2 games in exchange for a power-up. The Butcher option trades an injury for a talent. These are event choices; their reward tables are outside the scope of this page.

7. Injury immunity and prevention#

InjurySystem.CanBeInjured, CanHaveInjuryType and WasInjuryPrevented:

A blocked type sets wasPrevented on the result, and no injury is applied.
