Tetra weapons and tools enchantments are based off of parts. It matters what parts you put enchantments on. If you upgrade a part that has enchants you will lose the enchants it had on that part. I probably should have gone into more detail about that. Also, some enchants can be lost when converting from normal tools to tetra. So when you put a vanilla enchanted tool into the Tetra table, each part shows what enchants it has. You just mouse over the parts and it tells you. So you HAVE to replace at least ONE part when you upgrade a tool to tetra. So pay attention to the enchants and what tool parts they are on when you do the conversion. Sorry I didn't get into detail about it. 😊🌻
