Commitment
When a game action commits, some alternatives become temporarily unavailable. That constraint makes the outcome predictable enough for the player to plan a response.
Mechanics that use this lens
Charge
The boss aims, locks its direction, and charges forward. It cannot turn after the lock.
Attack patternsSummon
The boss calls a limited group of helpers, changing priorities without flooding the arena.
Body and meleeWide swing
A broad melee arc denies the space beside and in front of the boss.
Body and meleeLunge
The boss commits its body along a short line to close distance.
Body and meleeGrab
A grab replaces ordinary damage with capture.
Body and meleeBurrow and emerge
The boss leaves direct interaction.
Targeting and rhythmHoming projectile
A projectile adjusts its heading toward the player after launch.
BeamsStraight beam
The boss projects a sustained line of danger that controls a corridor and separates warning.
BeamsScanning beam
A sustained beam sweeps across space from one side to another.
BeamsRotating beams
Two or more beam arms rotate around a source.
Targeting and rhythmTarget lock
The boss selects a player or position.
Targeting and rhythmAttack combination
Two or more familiar attacks are sequenced so the first response changes the starting conditions for the next.
Body and meleeLanding jump
The boss leaps to a committed destination and turns the landing radius into a short radial threat.
ProjectilesSingle shot
The boss releases one discrete projectile along a locked line.
ProjectilesCrossfire
Two independent sources fire through the arena so their projectile paths intersect.
ProjectilesSplitting projectile
One projectile reaches a readable trigger, disappears, and releases several committed fragments.
ProjectilesReturning projectile
A projectile travels away from its owner, turns at a readable point, and creates a second dangerous pass on the way back.
ProjectilesOrbiting projectiles
Projectiles remain attached to one center and rotate as a spaced moving perimeter.
BeamsPulse beam
A fixed beam lane switches between dangerous pulses and safe pauses on a readable cadence.
Area controlChain explosions
A pre-announced row of blast zones detonates in order, turning each cleared zone into the next safe foothold.
Zones and trapsMine
The boss places an object that becomes dangerous only after arming and keeps one fixed trigger radius until it disarms.
ArenaMoving hazard
A persistent dangerous area travels through the arena, making the player plan against its future footprint rather than its starting position.
ArenaConverging threats
Separate threats approach one another, narrowing a previously safe region and asking the player to leave it before the overlap.
ArenaPull
An announced inward force changes the player's movement and can draw their body into a dangerous center.
Additional targetsTurret deployment
A boss installs a fixed weapon whose firing lane remains dangerous after the deployment animation ends.
Additional targetsThreat generator
A boss creates a source that repeatedly emits independent threats until its cycle ends or the source is removed.
Additional targetsDecoy
The boss presents a convincing false target, so the player must identify which body can advance the fight before committing an attack.
Targeting and rhythmPredictive aiming
The boss samples the player's movement and aims at an estimated future position, creating a readable invitation to change course.
Targeting and rhythmSource tracking
A visible firing source follows the player's current position during the tell, then commits to a fixed lane.
Targeting and rhythmBurst fire
A short burst repeats a projectile threat at a readable cadence instead of releasing every shot at once.
DefenseDirectional shield
A raised shield blocks attacks from a fixed front sector, but an ordinary move around its edge leaves the boss exposed.
Structure and readabilityWind-up
A wind-up is a readable pre-action state that gives the player time to identify and answer a pending attack.
Structure and readabilityAttack lock
Attack lock freezes selected attack parameters before release so the player's response remains valid.
Structure and readabilityActive phase
The active phase is the bounded interval in which an attack's collision can produce its gameplay effect.
Structure and readabilityRecovery
Recovery is the post-action interval before the boss may choose or start another action.
Space, movement, and perceptionTeleport
A teleport removes the boss from one position and restores it at another without dangerous travel between the two points.
Space, movement, and perceptionForced inertia
A surface or effect carries the player past ordinary input release and turns stopping distance into the central positioning rule.
Space, movement, and perceptionWraparound projectile
A projectile exits one linked boundary and re-enters from another while preserving its direction, speed, and remaining lifetime.
Encounter goals and vulnerabilityProjectile rally
Boss and player repeatedly return the same projectile until a missed response resolves the rally.
Encounter goals and vulnerabilityBaited self-hit
The player places or exposes a valid hazard, baits a committed boss action through it, and turns the boss's own resolution into damage or stagger.
Encounter goals and vulnerabilityPosture stagger gauge
Authored attacks and counters pressure a separate posture gauge; a break opens a bounded critical state that only an explicit finisher can consume.
