The Elona+ mod of Elona adds new hidden feats that are specific to their class. Because the feats are not detailed in the character sheet, they might not be noticeable at the start. This also means that the feats don't have a real name. The following table is ripped from the Elona+ wiki, but contains localization changes and some other minor changes.
It is possible to change Class feats with a Business Card by typing the name of the class in lowercase.
