Isabelle (SSBU)/Down smash

Hitbox visualization showing Isabelle's down smash.

Overview

Isabelle's Down Smash is her fastest smash attack, providing generous knockback for its startup time, and is usually safe on hit. It notably combos from her jab at mid and high percentages. However, the move is unsafe if shielded due to its significant end lag, and is a relatively unrewarding smash attack. This typically limits its usability to a guaranteed hit, kill confirm, or as one of her best panic moves. Despite this, Isabelle still greatly benefits from having a quick Down Smash. As a character who excels at ledge trapping and edge guarding, opportunities to send the opponent offstage are valuable.

Update 13.0.0 significantly increased the size of the sweet spot towards Isabelle, in turn granting Down smash slightly more vertical range. Knock back was slightly increased as well. While these changes marginally helped the move's kill power and range, it most importantly increased the reliability of hitting with the sweet spot instead of the sour spot.
