Fire Gauntlet

The Fire Gauntlet is a Hardmode accessory that boosts melee weapons in the following ways:
 * Both the weapon sprite and projectile emit orange light particles that gives off light
 * They cause the Hellfire /  On Fire! debuff (does not apply in PvP)
 * +100% knockback
 * +12% / +10% /  +9% damage
 * +12% / +10% attack speed
 * They gain autoswing (also applies to whips)
 * +10% size on some melee weapons

Tips

 * Crafting the Fire Gauntlet from the Mechanical Glove does not reduce any of its stat boosts, making it strictly an upgraded version of the latter.
 * One may probably find it more useful to keep the Mechanical Glove, since, unlike many other combined accessories, the Fire Gauntlet loses some functionality of its constituent parts. The Mechanical Glove gives 2% /  3% more damage and speed in its boost than the Fire Gauntlet, and the On Fire! damage from the Fire Gauntlet is negligible.
 * The Fire Gauntlet can be worn alongside the Mechanical Glove with the effects of both stacking, greatly boosting damage and melee speed. This is useful for the few hardmode weapons significantly affected by melee speed such as the Psycho Knife or Fetid Baghnakhs.
