Construction
構築術式
One object. One lifetime. That's the deal. Construction lets the user build a single real, permanent, physical object from cursed energy, but creating it burns every drop of cursed energy the user has. The act of making something is the act of dying. Most techniques produce temporary constructs that dissolve when the energy fades. Construction creates something that lasts forever, as real and solid as if it had been forged in a workshop. The permanence comes at the ultimate price.
