Eldritch Guardian w / Improved Familiar: Small Aether Elemental?

[Derrick Winters]

Hello everyone, I've been wondering how to act against the following "Enforcer" a GM has been using in a campaign:

It is -as far as I know- an "Eldritch Guardian Fighter" with a Small Aether Elemental as familiar who has the Bushwhack feat.

Because the Familiar is constantly invisible, and can fly, it can surprise the party easily. Its CMB / CL for Telekinetic Maneuver scales with the fighter's BAB and feats, and it has at least 700ft range and can basically instantly telekinetically pin someone in the surprise round while staying invisible and far away.

I know "See invisibility" exists, but this particular tactic seems extremely effective...

Does it work like this by the rules, and if it does, what tactics can you recommend against it?

The party is at lvl 5, a Whip Magus, a Geokineticist, a Slayer and a Cleric(Evangelist) of Abadar with the Leadership Subdomain.

Looks totally legit to me, and a great combination of feats and abilities. I assume the fighter himself has Improved Unarmed Strike, Improved Grapple, and Bushwhack, which is how the familiar gets access to the feats, through the Eldritch Guardian's Share Training feature? I do hope the GM is taking into account that the familiar needs to be able to see and hear its master to get the benefits of those feats, but that's not hard to do.

I think the best you're going to get is see invisibility and a really great ranged attack (probably from your Geokineticist) to knock it out of the fight quickly.
