Iron Sand/Gold Dust Manipulation[Limited]

Name: Iron Sand/Gold Dust Manipulation
Origin: Unknown
Type: Manipulation
Appearance: N/A
Description: After watching the Shukaku for many years, seeing how it controls its sand, a unknown Magnet Release user managed to mimic such a talent. Users of this skill are able to manipulate copious amounts of Iron Sand or Golden Dust much like the wielder of the Shukaku can manipulate sand. Both substances have a minor advantage over normal sand as well, as both weigh more than it. However, for some reason, wielders are not able to use both Iron Sand and Gold Dust. Thus, one must chose only one. They also go out and collect the iron/gold shavings to use them. It's 150 words per two pounds of shavings. The user must state how many pounds of Iron Sand/Gold Dust are used for a jutsu (in the case they are destroyed) and will have to buy a seal or a container to store the shavings.
Chakra Cost: -10 per Post
