Pathfinder 2E - Attacking while burrowing?

Starlit eyes, focus spell
True strike/target, 1 attack with advantage
Golbin-eye orb, talisman.

Think that's. Several to reduce hidden to DC5, but none better than blind sight.

So I will probably just go with rogue. Feels like a rogue thing to do, and they will be flat footed for sneak attack, and have skills to get into other safe position.
Ghost Arrows also come back after 1d4 days, so that's great. This is a repeatable tactic.

I'm also taking spyglass modification +wide overwatch (overwatch dedication) and seeker arrow (Eldritch archer dedication). So I can shoot around corners.

Any recommendations on ancestry? Oread can give me tremorsense and burrowing.
