Divination was the art of peeking into heaven's secrets to calculate one's fate and fortune, an act that naturally went against heaven's will. As such, performing such feats wasn't free of consequences.
Generally, lifespan was the cost of divination, which was akin to nothing for beings at the divine rank and above.
However, this is true only for low-level divinations.
High-level divinations that peek into major heavenly secrets, involving beings with great destiny or protection against such divinations, would generally consume more than just lifespan.
In such cases, besides the high cost of lifespan, there could also be a significant backlash in the form of a reverse energy flow, bad karma, heavenly tribulations, severe injuries, or even death.
"Empyrean Oceanheart, I'm afraid the price of divining my fate and fortune will not be small. It may harm you and may not be worth it."
Vaan politely refused Empyrean Oceanheart's suggestion.
