  2. Shoot the switch to the east at the start to lower either one or two invulnerabilities depending on your skill level. (sector 645)
  3. At the north cliffs in the secret forest, climb the steps, then jump across them to the south side of the fence. Head east and around to get a blur artifact. (sector 2087)
  4. At the northwest end of the secret forest, one of the trees has a berserk pack in the north end of the trunk. (sector 2207)
