Once there, land at the end nearest to the Clagmar Castle floo flame, and you should quickly find Selwyn. There isn’t much that is different about Selwyn compared to other infamous foes. He does have more health and higher defense than your regular enemies. He also has several Ashwinders around him, so be sure to watch out for their attacks while fighting with Selwyn.

Fighting Sewlyn in Hogwarts Legacy.

You can make use of the throwable objects around the castle to easily break shields and use your Ancient Magic to take larger chunks out of Selwyn’s health. All in all, it should only take you a few minutes to defeat him. The quest doesn’t require you to wipe out the camp, so it’s up to you whether you just kill Selwyns and return to Mrs. Olivier or wipe out the whole camp while you are there.

Either way, once you are done, make your way back to Cragcroft and turn in the quest to Hyacinth Olivier to receive your reward. There is a choice to ask for a bigger reward, but this won’t actually affect anything other than the amount of money you receive.
