This means via Familiar Spell

Spoiler:

You can imbue your familiar with a spell.

Prerequisites: Spellcaster with familiar class feature.

Benefit: You can transfer a prepared spell to your familiar, allowing the familiar to cast that spell at a later time. Variables that rely on caster level function according to your caster level, not your familiar’s Hit Dice, though your familiar’s Intelligence may influence how precisely it can follow your instructions on how to use these spells.

Your familiar must be able to speak to cast spells with a verbal component (the ability to speak with its master or creatures of its kind is insufficient). Your familiar must be carrying any material or focus components necessary, unless the materials cost less than 1 gp and the spell is prepared with Eschew Materials. Attack rolls use your familiar’s ability scores. A familiar spell counts against the number of spells you may prepare for as long as your familiar retains the spell. Once your familiar casts a retained spell, you can prepare a new spell in that slot the next time you prepare spells.

A familiar spell uses up a spell slot 3 levels higher than the spell’s actual level. Your familiar can store a number of spell levels (including this modifier) equal to your caster level, but no spell’s adjusted level can exceed half your caster level.

Special: If you are a spontaneous caster, you must select a specific spell with which to imbue your familiar; you cannot imbue your familiar with an open spell slot.

the familiar can hold 13 levels of wizard spells, and 17 levels of druid spells, for a total of 30 spell levels.

Yeah?

Looks like, but keep the three-level overhead per spell in mind. In that 30 spell levels you could only fit 7 1st-level spells, for instance.

Tehnically true, but I have no idea why anyone would waste their familiar spells on something like first level spells.

I'm thinking shoot for both traits that lower the spell slot level when you add metamagic to them and put a lot of focus onto baleful polymorph. It's level 5 in both lists. With both traits, it's level 6 as a familiar spell, and the familiar could then carry four castings of it, though I think holding back one for a greater dispel magic would be wiser.

[Azothath]

The caster cannot regain spell slots that are imbued unless the imbued spell is cast or effectively withdrawn (such as familiar killed and spells lost) AND the caster cannot get the spells back from the Familiar. I'd say it might be action economy but the GM is in control of the familiar.

Simulacrum is better and easier with less constraints.

While Magical Lineage and Wayang Spellhunter are nice, taking both on the same spell is generally frowned upon by GMs. So ask your GM first. There may also be retraining involved at some point.

the cap is on the familiar "Your familiar can store a number of spell levels (including this modifier) equal to your caster level" he can not have more spell levels then your caster. you have two cater level 13 and 17. which mean even taking the highest into account he cant have more then 17 spell levels.

even if they are counted separately. you forgot the +3 level adjusment. and that this is not amount of spells = caster level, it is spell levels = caster level .
as in a wizard's 'light' cantrip (will be adjusted to a 3rd level spell) will count for 3 out of the 13 wizard caster level limit.
so finding the max it can hold by picking lower spell levels:
wizard 13 = 3 cantrips (count as 3 levels) + 1 level 1 spell (count as 4)
and
druid 17 = 3 cantrips (9/17) + 2 level 1 spells (8/17)
for a total of 9 spells he hold (and your total spells per day drop 3 3rd level spells and 1 4th from the wizard and 3 3rd and 2 4th from druid)

giving up 6 spells of 3rd level and 3 of 4th so your familiar can cast 6 cantrips and 3 1st level spells seem wasteful for me.

compared to say a runegard10/wizard 10 who can give anyone(even his familiar i think) 10 spells of up to level 9 to cast with no feat needed and at level (not +3 adjustment).

Also note that Wayang Spellhunter doesn't work on baleful polymorph, since it's not 3rd level or below.
