I can confirm Geist Schritt keeps you at a diagonal, but none of my characters have the other two.

Cyclone Spear is a pull I forgot about, but I don't know how that one functions, either.

Cyclone Spear at its basic form pulls enemies within 5 range of the spear, one tile closer toward the tile where you placed the spear. It considers diagonal pulls to be 1 tile.

As far as I know, the only Elemental Impact which affects the pull is Raging (Talvyd), which increases the pull to 3 tiles. It still considers diagonal pulls to be 1 tile, successfully pulling a monster along a diagonal between two butterfly illusions, then two more tiles to the exact place I put the spear. If the butterfly illusions are absent, it still seems to make the diagonal pull, reaching the same final location.
