The so-called Escape Talisman was meant to release a fog from the talisman and take advantage of the momentary cover to escape dangerous situations.
Wythe saw his most proud apprentice killed by Basil Jaak, and his Ghost Talisman destroyed by the latter; he had no choice but to run, or else he'd likely lose his life there as well.
He quickly retreated, then suddenly pulled out a talisman from his bosom and shouted, "Escape!"
The talisman then began to emit bursts of white light, instantly covering the surrounding area for dozens of meters, the visibility reduced so one couldn't see one's own fingers, much like a high-grade smoke grenade used in modern warfare.
Having said that, Wythe hid within the dense fog. Since the person who released the Escape Talisman was immune to the fog, he could see clearly and escape quickly. Thus, Wythe quickly found the right direction and rushed towards the distant woods at high speed.
