Straight beam

Three questions for the mechanic

• Can the player read the complete rule?

  Draw the future line with aiming posture, light, particles, or a harmless guide before the damaging beam appears.

• Is the intended response reachable?

  The player leaves the corridor, crosses before activation, uses cover, interrupts the cast, or exploits the boss’s fixed facing.

• Does recovery create a useful outcome?

  The beam shuts down along the same corridor that was previewed, and the boss keeps its facing locked for a short punish window before aiming again.

Design mistakes

• If the damaging width exceeds the preview or the beam snaps after the warning, the telegraph teaches the wrong rule

  If the damaging width exceeds the preview or the beam snaps after the warning, the telegraph teaches the wrong rule.

• The cue and active geometry disagree

  If the visible straight beam cue promises a different area or timing, the player cannot carry the learned rule into the next cycle.

Tune the attack

• Tune the complete rule

  Measure warning time, beam width, active duration, rotation tolerance, and recovery against the distance needed to clear the whole player body.

• Escalate one variable at a time

  Add multiple fixed lines or shorten the warning after mastery while preserving the exact relationship between preview and damage.

• Prove the recovery

  The beam shuts down along the same corridor that was previewed, and the boss keeps its facing locked for a short punish window before aiming again.

Arena

• What the mechanic communicates

  The boss projects a sustained line of danger that controls a corridor and separates warning, activation, and recovery into clear timing phases. The encounter uses that rule as a short promise: a visible signal, a committed action, and a result the player can verify.

Player upgrades

• Adapt it to the player verbs

  The player leaves the corridor, crosses before activation, uses cover, interrupts the cast, or exploits the boss’s fixed facing. Measure warning time, beam width, active duration, rotation tolerance, and recovery against the distance needed to clear the whole player body.

Do not confuse this with

• Keep the mechanic distinct

  If the damaging width exceeds the preview or the beam snaps after the warning, the telegraph teaches the wrong rule. Do not hide that distinction behind extra effects or tracking that the announced rule does not contain.
