The brand-new Monster Hunter World Melee Weapons Editor Mod allows players to edit their melee weapons.

Created by modder ‘Aradi147’, the tool grants players the power to customize melee weapon data, including True Raw damage, True Element damage, rarity and much more. As you might expect, the use of this mod could result in people using massively overpowered weapons. As such, ‘Aradi147’ warns that players should only use this tool offline or in private sessions.
