Material Creation

Material Creation (物質創造) is an Intrinsic Skill inherent to the Daemon race. Rimuru had also gained it by learning it from Diablo, showing it can be taught.

Effects
It allows the user to create matter by expending Magicules. It is usually used to create weapons or garments, the grade of which depends on the amount of magicules used.

Rimuru, upon seeing his naked body after his evolution into an Ultimate Slime, had used the skill to create some clothing which were revealed to be God-grade. Velgrynd had also used it to create her "Blue Dragon Sword" which was also God-grade. However, it was vastly inferior to Rimuru’s katana which had been passionately forged by Kurobe, shattering upon impact with it as her sword was merely made of condensed magicules, showing that equipment made using this skill shouldn't be relied on too much.
