Obucite is a powerful resource available in Diablo 4. It is used to improve equipment during the late game. Most of this requires the use of the Blacksmith, which might take a lot of time and investment. However, it can be well worth it, as upgraded items can improve each class’s power. However, you may want to double-check all the possible upgrades and ensure they are right for your build.
