Veres

Veres are the blood of hunters who have killed humans; it is very rare due to the nature of Hunters. Hunters were made to protect humans from the Night Things - as such, if they go against their natural habits, Veres is created.

Usage
It was first shown to be used in Volume 2 when Grey shot an arrow coated in Veres at Daemon who caught it and let go quickly when it appeared to burn his hand. Veres is used in Volume 3, against Cassidy O'Rourke, Teresa, Ten and Jaq. It was called out by Theo, who was trying to get Marina Zaikina.
