Shortly after completing The High Keep main story quest, you will receive an owl from Natty asking you to meet her in Lower Hogsfield. Go there during the day and talk to Natty, then talk to Johanna Bickle, who is standing nearby.

Follow the quest path to Archie’s hideout in the Southern Forest. When you get to the hideout, wait for Natty to stop talking, then cast Revelio to reveal Archie’s footprints leading south. Follow the trail (follow Natty if you lose the trail) until you reach a clearing patrolled by black mongrel wolves. Defeat the Dark Half-Bloods, then find Archie’s satchel hanging from a tree on the south side of the clearing.

Examine Archie’s satchel, then relaunch Revelio to reveal more steps leading southwest. Keep following the path until you come to a fork in the path at a Floo Llama, then run Revelio again to discover not one, but two sets of footprints leading along the path to the left. The trail eventually leads to an Ashwinder camp, so sneak or fight your way to Ashwinder’s haunted tent on the other side.

Cast Disillusion and sneak into the shop, finishing off Ashwinder’s Scout and Ashwinder’s Assassin with Petrificus Totalus. After those two, you’ll come to Catrin Haggarty and other Ashwinder scouts. Try to take out all of these enemies using Petrificus Totalus without them seeing you, but don’t worry if they spot you because you can still pick them up and get dueling feats.
