Magus multiclass dedication Wizard, Witch, Psychic, or Sentinel

[The Dragon Reborn]

Hi,
I'm new to 2e and I am playing a Guisarme iron Magus. That said, I'm not impressed by the 1st, 2nd and 4th level magus class feats. My thought was to multiclass. I am imagining multiclassing for more slots/traditions or more tankability. I was hoping people who have played or seen Magi in combat could give me advice as to which direction I should head.

For tankability, I'm leaning towards sentinel. Sentinel buffs my armor by 1 and allows for armor specialization later. For Spells, I'm thinking Witch which offers spells, slots, traditions, a familiar and 1 tanky focus spell fast healing feat.

If I go witch, there's the question of which tradition. I'm assuming my witch spells will be buff and utility so mastery won't be too important. Occult, primal or divine would allow my magic items and I think the buffs are better for Arcane or Occult. I was think Occult for item access but can't tell if that's a real thing in pathfinder society play. What do you think?

To tank more, it is way better to go with witch dedication, taking heavy armor proficiency by lvl 3 with general feat.

By lvl 4 you will also get lesson of life and a full familiar, being able to get either the magus temp hp, the witch fast healing and a +1 AC from a heavy armor.

Witch will also reward you with more true strikes ( occult tradition would be the best you can get IMO), allowing you yo properly deliver Spelstrikes.

If you want to get more power, psychic dedication ( in order to get imaginary weapon) is definitely the way to go.

You'll also get extra true strikes and the heavy armor proficiency.

You just have to decide whether you want to use your focus spell to get fast healing or being able to use a stronger spell for your spellstrike.

I'd probably go with the latter, as it is always better to bring enemies down faster than getting a little sustain ( plus the temp hp from inexorable iron, the shield can trip and the full plate, are quite enough for a front line).

Ps: by lvl 11 you can retrain to get the sentinel dedication.

Psychic gives you the best spellstrike focus spell in the game at lvl 6(imaginary weapon) and occult slots will let you cast true strikes or mirror image, etc. As a melee magus, you don't have the int to utilize anything targeting a DC to begin with so the value of wizard dedication slots vs imaginary weapon and psychic dedication slots is limited.

Sentinel can be avoided in pfs. You won't get to a high enough level for it to matter vs a general feat for heavy armor. In non-society play, you can delay sentinel to levels 8-10 and retrain the general feat then.

Witch life boost is fine for maximum survivability but raw power is generally better. Familiar also serves as a convenient imprecise tremorsense if you make it a tattoo familiar with tremorsense.

Currently playing an inexorable magus at L12. Feat plan is:

Witch dedication rune patron (L2), basic witch spellcasting (L4), Lesson of Life (L6), Sentinel Dedication (L8), Multitalented Psychic Dedication Distant Grasp (L9), Mighty Bulwark (L10), Expert witch spellcasting (L12), Patron's Breadth (L14), Conflux Focus (L16), Master witch spellcasting (L18), Supreme Spellstrike (L20).

So I only plan to take 2 magus feats at levels 16 and 20. I prefer distant grasp psychic as it gives you an amp cantrip with one feat.

With a ring of wizardry, I have from witch one L1, one L2, one L3, one L4 spell slot. From magus 2 L6, 2 L5 spell slots. 2 L3 from studious spells. One L3 from familiar. 2 L1 from ring of wizardry.
