Critical Shots (Crits)#

A critical shot ("crit") is a shot rolled as critical at release. Crits hit harder (more puck speed), are a little more accurate, make the goalie less likely to save, knock out skaters the puck touches, and trigger a set of crit-themed relics.

1. The crit roll#

Total     = permanent + conditional          (CritOddsResult.Total)
IsCrit    = Random.Range(1, 101) <= Total    (integer roll, 1..100)

• Base crit chance is 2%. GetCriticalOdds starts with permanent = 2, conditional = 0.
• If Total >= 100 the shot is always a crit. Several effects return +500 to force a crit.
• permanent and conditional are added together for the roll. The isConditional flag only decides which bucket a source goes into, which matters for UI and quests, not for the roll itself.
• The roll is made once, when the shot is released.

1.1 How sources combine#

GetCriticalOdds(forward, shotType) builds the total in this order:

1. Start at 2 (permanent).
2. Every talent / power-up on the skater (SkaterData.powerups) that implements ICritModifier is asked for a value.
3. The skater's active ability (SkaterData.ability) is asked, if it implements ICritModifier.
4. Every team relic (TeamData.relics) that implements ICritModifier is asked.
5. Pucky Charms (BothTeamCrit): if the opposing team owns it and your team does not, its oddsIncrease is also added to your shots. That is the "for both teams" part.
6. Puck Pucks (CriticalMass): if your team owns it, both buckets are multiplied by multiplier (2.0) and truncated to integers. The multiplier also applies to the base 2%, so the base becomes 4%.

Only positive results are added (if odds > 0). A source that returns 0 or less contributes nothing. Sources stack additively before the Critical Mass multiplier:

Total = trunc( (2 + Σ positive modifiers) × CriticalMassMultiplier )   // multiplier = 1 if not owned

1.2 Which shots can crit#

Only two code paths roll for a crit: SkaterAbility::WristShot and the slapshot coroutine SkaterAbility/<_Slapshot>::MoveNext.

Notable: neither call site passes ShotType.OneTimer (5). One-timer slapshots roll as Slapshot. Because of that, Sweet Spot (CriticalOneTimerRelic), which only adds odds when shotType == OneTimer, appears to do nothing for the actual crit roll in this build. The bench-quest checker (BenchQuestSystem::OnShot) also calls GetCriticalOdds with the shot's ShootingArg.shotType, which may be OneTimer, so Sweet Spot can count toward quest progress such as the Kirby "100% crit chance" quest (inferred).

Source: SkaterAbility::WristShot (backhand check via SkatingAnimation::IsBackhand and CriticalShot::HasCritModifierSource), <_Slapshot>d__100::MoveNext.

1.3 Forced crits that bypass the roll#

2. What a crit does#

2.1 Crit strength (power bonus)#

CritPower = trunc( 50 × (1 + BoltPct/100 + StixPct/100) )
  BoltPct = Bolt relic ("D20"): 25 at level 1, 25+25 = 50 at level 2
  StixPct = Stix (CritBoost) talent: 25, only at talent level ≥ 2, and only if the skater's power-ups are enabled

For scale, an uncapped 100-Shot-Power wrist shot is about 50 speed and a slapshot about 70 (see shooting.md). A crit therefore roughly doubles wrist-shot speed.

2.2 Crit knockouts#

During a crit shot (ShootingArg.isCritical), any Forward the puck's trigger touches, other than the shooter, is knocked out if CanBeKnockedOut() allows it:

• knock force = 9 + 11 × clamp01((ShooterShotPower − 40) / 160) along the puck's travel direction
• Random.Range(5, 10) and Random.Range(2, 5) are passed as further Knockout parameters (likely the upward component and the knockout duration in seconds) (inferred mapping)
• willLoseStick = true and isCausedByPuck = true, so the victim drops their stick

Immunity: skaters tagged ImmuneToKnockout are protected because CanBeKnockedOut checks the tag (inferred).

3. Crit-related talents, abilities and relics#

Values come from the serialized assets. "Cond." means the source reports isConditional = true.

3.1 Flat or always-on odds#

3.2 Conditional odds#

3.3 On-crit trigger relics (no odds change)#
