Update History

3.1.0

• Up smash's last hit has more base knockback (32 → 38).

9.0.0

• Up smash has larger hitboxes (2.5u/2.5u/4u → 3.2u/3.2u/4.7u (clean loop), 4.6u → 5.1u (late loop), 5.5u → 6.5u (last hit)) that stretch farther horizontally (Z offset: -4u—7u → -6.5u—7u (loop), -4u—5u → -5u—5u (last hit)), with the last hit placed lower (Y offset: 24.5u—22.5u → 23u—21u). The looping hits also launch at different angles (120°/190°/140° → 105°/175°/140°), and their hitbox with the lowest priority deals more knockback (base: 0 → 30). Altogether, these changes allow the move to connect more reliably.
