The DATA/PCLASS directory contains a wide range of files, of which many are not read by the game itself. To see what you can modify to change the behaviour and configuration of the game, we've made this list of files that are actually loaded by the game's code.

• wclass.txt
• effectClass.txt
• pclass.txt
• customClass.txt
• monster.txt
• monsterExport.txt
• object.txt
