"The Warder's bond gives them increased endurance and strength," Moiraine says. "They are able to go without food, water, and rest, when needed, and may also withstand wounds that would kill an ordinary person. They also receive something of a sensitivity to certain types of enemies that are inimical to the One Power wielded by Aes Sedai."

She is carefully avoiding terms like Shadowspawn, for now, given certain ... misunderstandings... that might occur.

"Both Warder and Aes Sedai are able to sense each other through the bond, to a limited degree. It is useful for knowing the other's approximate location, for example, or if someone is injured or ill."
