I’ve put together an ESO Transmutation video guide for you! Transmutation in Elder Scrolls Online is how you can change the trait on gear (weapons and armor)! I go over everything you need, how to get it, where to do it and more! I also have a matching written guide for transmutation that goes a bit more in depth about how to get transmutation crystals and transmutation geodes.
If you prefer a written guide, you can check mine out here!
