Sand Form or Dust Form is the ability to assume a form which looks like the user is made out of sand, or a constantly-swirling sand cyclone/constantly-floating dust cloud. This form can be used to obscure the vision from foes, flay flesh (if whirling fast enough) or travel on air currents. The sand form can is malleable, and capable of not only assimilating into bodies of sand, but also changing density.
