A character sheet records the attributes that define your character. It records known spells, equipment owned and carried, money - everything about the character, in fact. The character sheet captures the core information. Additional sheets may be used to describe addition equipment, track money, etc. The sheets used here were developed by Blake Kirk many years ago and have proven to be an efficient way to represent a character. All sheet are very similar, but are customized by basic character class:
In the past, we printed these on colored paper to make it easier to find them among many notes. The colors next to the classes above are the colors we used to you. Feel free to follow that convention or not. Colored paper is not as common as it once was.
If you are playing a special character class, try to find a sheet that roughly matches one of the classes above. Thus, a shaman would use the cleric sheet, an amazon would use the fighter sheet, an assassin the thief sheet, etc.
