Bloodwing is one of nine optional trophy quests. It is obtained by killing a larger garkain, Vesper, which the Royal huntsman mentions. Only one trophy quest, The Beast of the Sewers, is not optional, making a total of ten.
Talking to the Royal huntsman in the druids' cave lets you learn about a garkain haunting the swamp cemetery. There are a couple of other garkains with him, and several wraiths might join the fight as well, so using Vampire oil is highly recommended. The target is set apart by his name, Vesper, and the fact that he is slightly larger than his compatriots.
- Do not pursue him into the Cemetery as you might also run into Lilly. Geralt's inventory can only hold one trophy at a time! The second head would have to be retrieved later and may prove difficult to find again.
- You will only encounter Vesper in the cemetery at night!
I killed the web-winged monster that roamed the swamp. I need to deliver proof of having killed it to the Royal Huntsman. I need to take proof of having killed the garkain to the Royal Huntsman.
