There are several issues here. First of all, this weapon with maxed out enchantments can onehit nearly any player on headshot with maxed armor, besides Ametrine. Secondly, for whatever reason, enchanting it with crystalline and puncturing makes it the strongest melee weapon, due to having no durability loss on hit and allowing clickspam. Both of these should be overlooked (Also general issue with enchantments is that they also proc in offhand, meaning you can max out a tool with amethyst imbuement enchantments and augments and put it in your offhand and your mainhand weapon will have all the abilities)
