Kinetic invocation choices

[Sapreaver]

Hi, I'm playing a void element planar purist kineticist and my third level feat is the Kinetic Invocation feat.

I'm doing a gravity themed Kineticist and I can't think of any gravity spells aside gravity sphere.

Do you guys know of any second or first level spells I could grab at 4th level for my wild talent?

Going off list in the first place is up to your DM. They already ok with it? Because otherwise you're stuck with life channel (1st; 0 burn; self only), command undead (2nd), Animate dead (3rd), halt undead (3rd), unliving rage (3rd), death ward (4th), and mind blank (8th; self only),
