Ground slam

Three questions for the mechanic

• Is the signal specific?

  Make the lift, impact point, and exact contact frame distinct from ordinary movement.

• Is the response reachable?

  Compare wave speed with running, jumping, dodging, and the arena boundary.

• Is the opening useful?

  Give the slam enough recovery for the successful response to change the fight.

Design mistakes

• Hidden rule

  If the signal does not reveal the impact center and wave edge, the hit feels arbitrary.

• Wrong scale

  If timing is tested only at one upgrade level, the pattern can become trivial or unavoidable.

Tune the attack

• Match visuals and collision

  The visible threat must match the active hitbox in space and time.

• Start with ordinary abilities

  Keep one response available with abilities the player already has.

• Retest upgrades

  Check movement, range, damage, and invulnerability against every phase.

Arena

• Make the arena support the rule

  Keep the floor and wave edge visible; slopes and decoration must not mask timing.

Player upgrades

• Respect player upgrades

  Test the strongest available build. If an attack is blocked, make the immunity clear and preserve another useful response.

Do not confuse this with

• Name the exact pattern

  A slam is the impact; the shockwave is the expanding threat it may create.
