Notes & Tips

  • The first time you enter this area, you gain 500 XP.
  • If you talk to the Royal Fire Slug with Pet Pal, you discover that the slug was betrothed to Braccus Rex. If you tell her Braccus was vanquished long ago, she is overjoyed by the news, and reveals her name as Princess Zenthia. She gives you a letter and tells you to spread the news of her being free once more. (This gives 0 XP, but makes the Fire Slugs neutral towards you.)
  • Killing every slug in the area gives a total of 3000 XP
  • If you wish to avoid fighting the slugs, you can sneak through (B) or (C). Alternatively, you can use a teleportation skill (such as Tactical Retreat or Cloak and Dagger) to cross the gap between the two (2)'s
