Witch Spellbook?
 

So maybe I am confused, I created a human fighter how took the witch dedication as an ancestry "Multitalnented" feat and then added "Basic w
Witch Spellcasting" as my my next class feat.
I can see the "Witch Spellcasting" box it tells me i need to select 2 1st, 2 2nd and 2 3rd level spells. I took the feat at level 10... But there is no "Spell book" or "Familiar spell " panel....

Long story short? How do I add spells....I am not seeing it

"Familiar's Spells" can be found in the character's Gear.

Yeah, it's not obvious.

Oh Thank you! I would have never looked there....Wonder why it is different?

Well, that's where other spellbooks go, so it was probably simplest to put the Witch's Familiar spells there as well.

Yeah, we had a bit of debate over this one. Rather than get super complex with making new mechanisms to cram inside your companion, we settled on having witches' familiars add a "spellbook" item to the character, hence why it behaves like and appears with other spellbooks.
