"Prometheus's Stone Tablet"...
A special Silver Level item, according to the description, it is a very unique Holy Relic, with extremely singular effects, which might be why it appears sufficiently powerful.
As a tablet bearing the name of the most famous Fire Thief in mythology, it naturally possesses the ability of theft, but not in the conventional sense of the word. It specifically targets theft of Divine Power—it's said that this tablet can steal a portion of the gods' power and seal the stolen power within it, allowing the holder to use this power...
However, it can only steal one Authority at a time, and only one Authority can be stored in the tablet simultaneously.
Furthermore, the side effects of the tablet are not to be underestimated—or rather, it cannot be called a side effect since it only steals Divine Power, not the costs that the user must bear to wield Divine Power, nor the tremendous burden on body and mind.
