To create an inscribed item with the Elemental forging method, there were many hurdles to surpass.
The cultivator had to endure the absorption of the "Breath" with his sea of consciousness that comported a big risk for that center of power.
Then, he had to set his will on a specific meaning and imbue the "Breath" with that, otherwise there would be no effect attached to the finished product.
After that, it was time for the choice of the materials.
The compound had to be something that didn't conflict with the element of the cultivator and that could sustain the activity that it was meant for.
For example, you couldn't use a hard material to create a whip, it would simply conflict with the purpose of the item.
At the same time, you couldn't use something too soft either, a whip forged that way would just fail to inflict any damage when wielded.
The last hurdle was its form.
