I look in aonprd and get confused.
In witch Multiclass dedication, it is noted that you get a witch's familiar.and that: "Your familiar has one less familiar ability than normal." (its not saying that you get a familiar with 1 ability though)
Witches' familiars get extra abilities: "Your patron has sent you a familiar, a mystical creature that teaches you and facilitates your spells. This familiar follows the rules here, though as it's a direct conduit between you and your patron, !!!!it's more powerful than other familiars!!!!. Your familiar gains an extra familiar ability, and gains another extra ability at 6th, 12th, and 18th levels." (as I understand this ones are fixed to familiar not master abilities)
Does wording mean, that witches dedication gives 1 cantrip, (2 in spell book)1 familiar which improves as you level. (2 at 1, 3 at 6lvl, 4 at 12th)?
So compared to other casters you get 1 less cantrip at the start, 1 less skill, spell book vs whole spell list (druid/cleric), no language (druidic) and trade that with a familiar who is leveling up with you?
So, you can read it as familiar with 1 ability, or familiar with 2+ abilities (1+ of which is are fixed as non master abilities).
1 ability is making it lackluster compared to wisdom casters: small prepared spell list which you should pay for, less cantrips and a familiar which is able to do very little, not a good scout, not even okay at anything until you feed it with feats.
