When I think of the 3D elemental wheel I like to use the shape of a crystal in the game, an elongated hexagonal bipyramid. But for the sake of removing one more complication I just did a regular hexagonal bipyramid when I made this reference back when Shadowbringers inverted the polarities.

If I knew I'd be using it so long I would have proofed it better; that green line is going to haunt me for the rest of my days.
