Question regarding crafting

If I have a blueprint for weapon (in my case Leviathan) can I craft a Mystical Leviathan or only a regular Leviathan using that blueprint. I’m level 90, so I am preparing for when I reach level 94 and can use the Mystical Leviathan, but I’m unclear if that can be crafted or if I need to farm that (the item database I checked does not list a blueprint for Mystical Leviathan, only Leviathan).

What does your blueprint say, Leviathan or Mythical Leviathan?
