Tips, tricks & notes:

• If you have to leave the quest area, you can get back at a later time by talking to the spirit girl, Summer. She can be found at the quest's starting location, north of Varrock.
• Except for the summoning pouches, all of the required items spawn at the quest locations. There is no need to carry a lot of items.
• Wear Jennica's ring and operate it while standing on a portal to the other realm to get additional one-time xp. You must have level 50 in that skill to receive the xp:
  • Western Ruins - 15,000 Farming xp
  • Forgotten Cemetery - 15,000 Prayer xp
  • Axe Hut - 11,250 Attack xp
• At the Forgotten Cemetery, closing the coffins in the spirit realm will spawn four level 79 ghosts in the real world. Anyone can attack them.
• At the Axe Hut, the building in the spirit realm is occupied by level 42 ghostly warriors which you can do battle with.
• Jagex states that wearing Jennica's ring improves drops from killing revenants.
• If you lose Jennica's ring, you can recover it by searching the pile of rubble next to where you begin the quest.
