When a harrower gains a level, she gains new spells per day as if she had also gained a level in a spellcasting class she belonged to before she added the prestige class. She does not, however, gain any other benefits a character of that class would have gained. This essentially means that she adds the level of harrower to the level of whatever other spellcasting class she has.
If the character had more than one spellcasting class before she became a harrower, she must choose which class she adds each harrower level to for the purposes of determining spells per day.
A harrower adds the harrowing spell (see page 295) to all of her spell lists as a 3rd-level spell if it is not already on a spell list.
