Arcanist spells dos and donts

[Gilmore Vin Liktdenstein]

I have a level seven arcanist no archetype and i was wondering if anybody had any reccomendations for spes or spells to avoid

By that level, you should have the quick study exploit, so there really isn't much to be worried about. Almost any spell can be useful once.

The core strong spells are conjugation control, and buffs like haste. If you have those or summons you can do anything after that.
