This guide shows the optimal path for all 3 Treasure Hunts during Labyrinthine Cliffs meta event. You can achieve the best result with the Skyscale. Individual routes are color-coded.
You can toggle them in the GW2TacO / BlishHUD menu -> Tekkit's Guides - Festivals -> Four Winds -> Treasure Hunt. If you don't see these routes in the game, double-check if you properly followed Installation Instructions. If you still have issues, let me know in the #all-in-one-issues channel on our Discord
