'Beeting' A Curse

Speak with Samantha Dale at the Greenhouse Floo Flame to accept the 'Beeting' A Curse side quest.

Receive the "Crest of Marmaduke Gilbertus Dale" from Samantha.

Follow the quest marker to Dale's Tomb, located on the east side of Hogwarts Valley.

Upon entering, proceed down the main hallway and take the first left to find a chest containing Frameless Tinted Spectacles.

Continue into the tomb. You will encounter Devil's Snare; use the Luminose spell to clear a path. Avoid touching it, as it results in instant death.

A slip down a rubble hill will lead you to a Riparian Troll, an Infamous Foe. Use Protego and projectile spells, and dodge its attacks. Building combos increases your Ancient Magic meter. Revelio is not useful in this area.

After defeating the troll, head southeast to find Marmaduke's Sarcophagus.

Place the Crest of Marmaduke Gilbertus Dale on the sarcophagus. Pick up the Dittany leaves and check the nearby bag for a loosened crimson lock scarf.

Exit the tomb by following the white map marker. Use Revelio on your way out to find additional items.

Return to Samantha Dale to report your success.
