Character development is one of the chief draws of Ragnarok. Throughout the game, the player may change forms, to obtain the powers and abilities of almost any monster in the game, with the exception of god and demi-god level creatures.
In the beginning of the game, the player must choose a character class. These classes all have intrinsic statistics. At level ten, the player "masters" a class, and gains all the skills that the class can use.
One element of Ragnarok gameplay is that slain player characters leave behind 'ghost data' for the next adventurer to encounter.
