This extra feature required Mechanical Mages to consume various special materials to craft their own "Spell Formula Book."
The formula book would record any special abilities you've already mastered, such as potion-making, disassembling magic items, extracting magic materials, enchanting magic items, repairing and crafting magic items, and being able to permanently inscribe spells they had mastered onto some magic items.
The emergence of this ability directly allowed Mechanical Mages to inscribe magic knowledge on magic tools, among which the most representative are the Magical Wand and——
Golems!
If it weren't for this ability integrating all the capabilities of Mechanical Mages, transforming their skills into rapid production of magic mechanisms, generating cheap golems, or preparing high-precision golems in advance.
