If each official mage of the Demon Clan possesses five Osteo Wands, this would grant them double the elemental attack capacity compared to Aegean mages. Furthermore, they would also gain an advantage in instant casting power—something Liu Zhenshock can definitely appreciate.
Regarding this, Old Liu doesn't harbor any envy. The Demon World has always been ruled by a dictatorial government, with a standard centralized power. These bony jewels extracted from the mutated Arcane Beasts' skulls have strategic significance. In other words, they are innate weapons and equipment that no Witch King in power would ever forgo for centralized collection, management, and distribution.
In ten thousand years, how many Osteo Wands could the mutated Arcane Beasts of the Demon World produce?
With such a long accumulation period, the number must be astronomical!
Following this calculation, it's no surprise each official mage of the Demon Clan possesses five Osteo Wands.
