Trivia

 * This is considered to be the one of the best melee weapon, ahead of Shadow Fury and Livid Dagger, and behind Valkyrie and Scylla.
 * Currently, it has the highest base damage of any obtainable weapon (excluding the Emerald Blade with or more)
 * Its base damage is equivalent to that of an Emerald Blade with.
 * When using this weapon, it is recommended to reforge talismans to give Attack Speed. Some common reforges that can do this include Strange, Bloody, and Itchy. When reforged correctly, you can achieve 100% attack speed with Giant's Sword while doing much higher damage than a Livid Dagger or Shadow Fury. However, it is easily worse than Valkyrie and Scylla due to both weapons giving Ferocity, which Giant's sword does not give.
 * When fully enchanted and with Withered reforge, full Hot Potato Books, and full Fuming Potato Books applied, it can deal extremely high amounts of damage.
 * With the One for All ultimate enchantment, its base damage with Fuming Potato Books goes from +530 to +1643. Paired with the Withered reforge, this combination deals a significantly higher amount of damage than an normally enchanted one would do, while still being cheaper. Outside of dungeons this combination together with Elegant Tuxedo, Ender Dragon pet, Crown of Greed and a high combat level this sword is easily capable of hitting for over a 1,000,000  a hit.
 * Inside dungeons, it is not recommended to use One for All (unless it is not your main weapon) as enchantments like Syphon is extremely important for staying alive, especially for higher floors (F5+).
