Ok so as it reads-
The witch also selects a number of additional 1st-level spells equal to her Intelligence modifier to store in her familiar. At each new witch level, she adds two new spells of any spell level or levels that she can cast (based on her new witch level) to her familiar. A witch can also add additional spells to her familiar through a special ritual.
Is this saying the Witch's Familiar can also cast these stored spells?
ofr after the Witch uses her spells, she can call upon the Familiar and recast/cast said stored spells?
It's saying that the witch stores his spells in his familiar. That's the witches spells. The witch has no other spells than those stored in the familiar.
Got it, thank you.
