flat triangular surface
A flat triangular surface subjected to high-voltage AC, approaching and exceeding the breakdown voltage in air will start to form corona plasma at the edges of the triangle, with the effect most pronounced at the apex, if the other corners are closer to ground potential. Arrange 3 such surfaces in a tetrahedron shape, and you will have 3 surfaces discharging at that apex.
The points closest to the coil, will be the places were an arc can form inside. No wires necessary. You do want to care about the proximity, however.
The ability to arc varies with distance and the potential on the surface.
