Ambushes
The Wight commander let the troops bombard the town and after some time, he asked them to retreat.
He decided to use guerilla warfare and destroy the town bit by bit.
After everything calmed down and all the soldiers came back escaping the wooden bolt shooting range, he once again met with the rest of the Wights, Vampires, and Ghouls.
There is one question in everyone's mind.
"How can he use Undying Volcanic stones in the morning?"
This question is eating on their minds. It is already a big feat for a human or a dwarf to use the undying Volcanic stone, but using it in the morning is even impossible for them, much less a human or a dwarf. But to be able to use it and think of a better way to use it, they are feeling vexed.
