Teleport is a discontinuous position change, not a fast dash. Kern dissolves at 0.55 seconds while a destination rune appears at 0.72. With body collision off, the boss reforms there by 1.70 and commits to a fixed vertical strike from 2.36–2.72 seconds. Tavi reads the destination, clears the lane, and uses the opening.

At 0.55 s Kern begins dissolving at the origin. At 0.72 s a shrinking destination rune appears at the exact reappearance point; the boss body and contact collision are absent from 1.05–1.52 s.

Implementation checklist

Implement departure, absence, destination reveal, reappearance, follow-up commitment, collision authority, and reset as explicit timed states driven by one destination record.

Core checks

Three questions for the mechanic

  • When is the destination chosen?

    Capture one legal destination before disappearance and keep it immutable through reappearance and the follow-up. Validate arena bounds, navigation, camera framing, overlap with players, and reserved hazard space before committing. In the example the destination record is exposed at 0.72 s and never retargets.

  • What exists while the boss is absent?

    Disable body, contact damage, targeting sockets, and hittable hurtboxes with one authoritative absent state. Decide separately whether status timers, projectiles, summons, and arena ownership continue. Visual disappearance must not leave an invisible collider or a damage trail between the two points.

  • What follows the reappearance?

    Treat arrival and the next attack as one authored package. Kern reforms by 1.70 s, then previews a stored vertical lane for 0.66 s before its 0.36 s active window. Reappearance cannot overlap Tavi, the lane never tracks after reveal, and recovery starts only after collision is off.

Design mistakes

  • The boss appears on top of the player

    A random destination that becomes known only on arrival converts spatial reasoning into guessing and can create unavoidable contact damage. Reserve space around players, expose the destination early, or provide a guaranteed escape interval after arrival.

  • Teleport is implemented as a hidden dash

    Sweeping collision along the line between endpoints contradicts the visible disappearance. If transit should damage, show a beam, trail, portal connection, or moving body and classify that geometry explicitly instead of borrowing the teleport label.

Tuning

Tune the attack

  • Budget information, not only time

    Measure departure recognition, destination search, camera travel, response choice, and movement clearance separately. A long delay can still feel unfair when the new point is off-screen or indistinguishable from ambient effects.

  • Author destination policies

    Random does not mean unconstrained. Tag destinations by range, angle, line of sight, elevation, recent use, and compatibility with the next attack. Weighted selection should avoid repeats and impossible combinations while retaining variation.

  • Preserve state across the gap

    Store health, phase, cooldowns, captured target, facing policy, and queued follow-up before hiding the actor. Networked and rollback builds must replicate the destination and state transition, not infer them independently from effects.

  • Test camera and edge cases

    Exercise destinations near walls, platforms, split-screen edges, target-lock limits, summons, and multiple players. Verify the frame before absence, every absent frame, arrival, the first active frame, interruption, death, and loop reset.

Arena

  • One rune closes while another opens

    Kern collapses into fragments at the origin as a paired rune ignites elsewhere. The same rune channels the next strike, so the magical fiction communicates both where the elemental returns and what space it will threaten.

Player upgrades

  • Let Tavi answer with ordinary movement

    Tavi does not need a special teleport counter. The destination rune creates an early spatial read, the fixed lane makes a sideways step sufficient, and the recovery preserves the familiar sword response once the danger has ended.

Do not confuse this with

  • Discontinuous relocation, not burrowing or a dash

    A dash occupies and crosses intermediate space. Burrow-and-emerge usually hides a moving source whose emergence point is part of a subterranean route. Teleport has no collidable transit between endpoints; portals may add a persistent connection, while a swap exchanges two actors or positions.
