SPELL: The Spell section is used only for spell casters.  This area points out the number of spells known (sorcerers, bards), the number of spells per day and what level those spells are.  It also states the save DC for spells of that level by the caster.  

This section works with the spell planners to develop an overall view of spells available.  While all this data is available on the spell planner, it is listed on the back for the player to have a quick and convenient table to lookup data about a given level of spell.

You can also adjust the casting class with Bonus Levels. Those white areas add to the level of the caster for Spells/day and Spell Known! This is useful when a class (often prestige) adds to the level of an existing casting class.

FEATURES: The features section contains a whole wealth of information about your character. It can be considered a reminder of all those details applicable to your character. Beyond that, it can also contain some tracking for abilities that are limited. For instance, if you check the Turn Undead ability from the Cleric class on the right, you will notice that the "3x per day" is followed by "< OOO >". Those 3 circles are used to check off each time that ability is used (per day).

The Feature section will also list all conditional bonuses a character has. These should be applied when the proper circumstance occurs.

The Character Status section will list all errors the Sheet has detected (if any). You should always keep an eye on it to avoid any problems!!

Finally, note that the Class Features are pulled off the ClassFeatures worksheet.
