A Sapphire Elegy has a smooth, conical, dark blue body that is sapphire blue at its base and has a Heartless emblem emblazoned on its chest. The top of its body flares outward and forms a jagged "collar" below the Heartless's spherical, pitch black head. It also wears a conical, dark blue hat that has a sapphire blue tip, a turquoise inside, and a jagged brim and a thin, curled tip coming out of a yellow and black band. Useless feet hang out of its body; each sporting three thin toes that appear below its body.
The Sapphire Elegy's name has the same structure as other Heartless in its family, consisting of a color—in this case, sapphire blue—and a musical term—in this case, an elegy, a song set to a melancholy tone, usually to mourn.
A Sapphire Elegy can be quite an annoyance to defeat if the correct strategy is not used against one. They are not all-out offensive, but they warp to new locations when hit with either physical attacks or magic from head-on. They may also perform a swiping tactic, which is merely used as a means of knocking the player away. This can be avoided with a well-timed Dodge Roll.
Lastly, these Heartless have access to a headbutt attack which can be avoided with Dodge Roll, Block, or even a colliding physical attack of the player's. If hit by their physical attack, there is a 20% base chance that the Flip-Foot status effect will be inflicted, which reverses the controls that control the character's movement.
When it comes to eliminating a Sapphire Elegy, it is best that the player launch all physical or magic-based attacks from behind, or block the Sapphire Elegy's headbutt to leave it vulnerable to both physical and magic attacks. Despite the great struggle it may be to eliminate a Sapphire Elegy, these Heartless may drop any one of the three Rune Tech items.
