Steel Release: Accelerated Decomposition

This is larger and more advanced version of Steel Release: Manipulated Steel Dissolution. After weaving the needed hand signs, the user strikes a large object such as a building, injecting a large amount of chakra into it. Due to being Steel Release chakra, the attack merely phases through wood, stone, brick, etc. However, when it comes in contact with metal containing iron atoms, the chakra rapidly disrupts the atoms until they rust into weakened and brittle black material and break away. If a building has metallic supports that contain iron, the building quickly suffer and collapses in seconds from every metallic object decaying into dust. This technique is mostly used for destroying abandoned and unwanted buildings, but it can be destructive if used by missing-nin, who can eradicate a number of buildings in a settlement. A living creature with iron in their blood can suffer severe sickness and death if struck by the technique as well.
