A broad melee arc denies the space beside and in front of the boss, asking the player to leave the arc, pass through it, or exploit the unprotected side.

Show the weapon’s start side, shoulder rotation, and intended arc before the hitbox becomes active; the pose should reveal whether the swing is high, low, or full-height.

Implementation checklist

Tune the signal, commitment, geometry, response, and recovery of a wide swing as one rule.

Core checks

Three questions for the mechanic

  • Can the player read the complete rule?

    Show the weapon’s start side, shoulder rotation, and intended arc before the hitbox becomes active; the pose should reveal whether the swing is high, low, or full-height.

  • Is the intended response reachable?

    Support at least one ordinary escape such as stepping out, moving behind the boss, or timing a dodge through the active edge, then leave a short punish window.

  • Does recovery create a useful outcome?

    The weapon completes its arc and the boss holds the follow-through long enough for the unprotected side to become a real approach route before the stance resets.

Design mistakes

  • If the hitbox leads the weapon or extends far beyond it, the player learns to distrust the animation instead of reading the arc

    If the hitbox leads the weapon or extends far beyond it, the player learns to distrust the animation instead of reading the arc.

  • The cue and active geometry disagree

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

Tuning

Tune the attack

  • Tune the complete rule

    Tune reach, angular speed, active duration, and boss rotation together; test the slowest legal movement option at several starting distances.

  • Escalate one variable at a time

    Add a delayed reverse swing or a second height only after the base arc and its safe side are readable on their own.

  • Prove the recovery

    The weapon completes its arc and the boss holds the follow-through long enough for the unprotected side to become a real approach route before the stance resets.

Arena

  • What the mechanic communicates

    A broad melee arc denies the space beside and in front of the boss, asking the player to leave the arc, pass through it, or exploit the unprotected side. 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

    Support at least one ordinary escape such as stepping out, moving behind the boss, or timing a dodge through the active edge, then leave a short punish window. Tune reach, angular speed, active duration, and boss rotation together; test the slowest legal movement option at several starting distances.

Do not confuse this with

  • Keep the mechanic distinct

    If the hitbox leads the weapon or extends far beyond it, the player learns to distrust the animation instead of reading the arc. Do not hide that distinction behind extra effects or tracking that the announced rule does not contain.
