The Wreath of Immortelles is a quest item which is received as one of three possible rewards for killing the wraiths of the Wild Hunt for the hermit during the Hunting the Wild Hunt quest. The other two choices are: Geralt's own hut (really not worth it!), or a book on vampires. When Geralt asks the hermit what the Wreath of Immortelles does, the hermit responds: "You might find it useful..." Later the hermit reveals that it can break a curse binding nightwraiths.
