Incantations
Spellcasting runs through this combination. Toss energy out of the hands, collect it back in, then release it through the pelvis and up the spine. Picture an orb between your hands, and peel it apart slowly, like saltwater taffy.
The vocabulary is mixed: ballet technique, loose popping and locking, waving and isolations. You move in and out of the floor and find your leg.
Stay on the ominous, creepy side. Curious feet explore the floor.
