The expansion contains new items, weapons and armor, some of which belong to specific occupations, while others can only be found in the difficulty of hell. After completing the first four chapters, the characters can enter the new fifth chapter, which includes brand-new devil characters and other challenges. Many demons are almost unaffected by some kind of attack, which is especially obvious in difficult setting.
In addition, inlaid gems also add "jewelry", which has magical properties in itself. Jewelry is similar to a gem to some extent, but it will bring some magic equipment after inserting equipment, and jewelry will also have some random magic properties. The introduction of rune system greatly enriches the content of equipment strengthening.
