Shining Dust Magic

Shining Dust Magic is a Caster-Type magic based on dust seen on moths' wings.

Description
The user creates a big torrent of shining dust. It blinds opponents, but later it's seen to be caustic. Silvia could even get rid of a big, metal wall using it. There are some rumours that it can completely blind someone, who's in the mist too long. This magic has got some disadvantages:
 * 1) When the user uses this magic to attack Wind Magic user, it's hopeless.
 * 2) The dust blinds the target, but also the user cannot see anything after using this magic.
 * 3) It's got caustic effects, but it doesn't work on humans and living objects.
