Hammer Hammer Fruit
Type Paramecia
Allows the user to create objects using the earth around them (dirt can be turned into a turret), the name comes from a blacksmith's most useful tool: his hammer!
Pros:
You can make almost anything you want with enough mud/dirt/dust/sand/rocks.
Don't have to build it yourself just think of it
Creation will have all the properties of an actual thing, so if you made a gun out of dirt it would be as hard as an actual gun and look like a gun
Can be made within seconds-minutes depending on size and complexity
Cons:
User must know the schematics of what he makes and have an image in his head, you need to get the placement of everything right
It must be able to work in real life (no randomly creating space teleportation guns)
Need sufficient amount of resources to make it meaning a 4.3 kg AK-47 will need 4.3kg of dust/sand etc... to make it.
I recommend carrying loads of blueprints, someone like Franky would benefit greatly from an ability like this
