Even Lin Li's expression changed after he had analyzed all 13 of the mageweaths. This was definitely the work of a Guru, and was comparable to the All-Kill Array of the Tower of Dusk. In fact, it was even more cleverly designed than the All-Kill Array.
The 13 mageweaths encompassed decay, gravity, deadly poison, fear, hallucinations, seduction, and the dark. Under the control of the mageweath array, these seven different kinds of energy were able to take on any formation and become frighteningly powerful. Moreover, the mageweath array relied on the Gloomy Dark as a source of mana—in other words, the 13 mageweaths were able to directly absorb energy from the Gloomy Dark.
That was the highlight of the entire mageweath array in Lin Li's opinion.
