Indeed, it seems to be a useful jutsu to me xD
*Shinta begins by kicking his foot along the ground, stirring up a large volume of dust mixed with his doton chakra that rapidly forms into a dust storm. Within the dust storm, Shinta condenses the dust within the storm into five marble-sized balls that shoot forward towards his target, piercing it through.*
I take it a high level sensor would also be able to detect the balls of dust forming, in the same way a doujutsu user can see the denser chakra?
