The legendary affix of Frantic Sword '1% HP recovered per melee attack, up to 50%’ will heal to exactly half HP when you have an even number of HP, allowing you to crit; if you have an odd number, it heals to one HP more than half HP, getting rid of the ability to crit.
In earlier stages of the development of The Baguette Update, this weapon was named Scavenger, which was a direct translation of the original French name for this weapon, Charognarde.
The mistranslation is still present on the steam trade card.
In the front cover image of physical copies of the game, a Frantic Sword can be seen next to the right hand of the Beheaded.
