Usage
This fruit is mainly used by Katie to tamper with Devil fruit like powers, transforming random objects in the environment into usefull tools or weapons. She can also sabotage other people's devil fruits, provided they are unprotected, most spectacularly by generating another Devil fruit like aura inside their body, predicatably causing a fatal overload followed by (apparently) spontaeneous combustion.
