So I'm pretty new to witches and I'm trying to figure out something. A familiar for a witch has spells "known"
Witch's Familiar (Ex)
At 1st level, a witch forms a close bond with a familiar, a creature that teaches her magic and helps to guide her along her path. Familiars also aid a witch by granting her skill bonuses, additional spells, and help with some types of magic. This functions like the wizard's arcane bond class feature, except as noted in the Witch's Familiar section.
A witch must commune with her familiar each day to prepare her spells. Familiars store all of the spells that a witch knows, and a witch cannot prepare a spell that is not stored by her familiar.
I realize that this might be flavor text as opposed to RAW, so I'm asking you guys.
Do witch familiars get new spells known when gaining a level in a prestige class that grants a level in spellcasting?
It would seem to me it would be horrendously expensive if it didn't. Barring finding familiars from other witches to learn spells (and good luck doing that for every level of the PrC), you'd have to buy a scroll of the spell each time. Seems it might be cheaper to release your familiar and bind a new one to get access to spells, correct? Seems to me that 2500 GP (assuming you enter a PrC at 5th) would be cheaper than buying high level scrolls.
