Spirit of Summer

Starting off
Start by going in to level 26 wilderness. The quickest way to reach the quest start point is to teleport to Clan Wars by Games necklace. Find the "abandoned farm" (marked as ruins on the world map). It is in between the Clan Wars and Bounty Hunter, just north of the Graveyard of Shadows. You will find a "spirit". Follow her until she enters a house. Follow inside. You get a message that you are being pulled by a force and are asked if you want to follow it. Choose yes.

You see a man who traps the girl in a sort of rings. Equip the Ghostspeak amulet. Talk to the man. He doesn't answer. So, use the opposite emote that he uses (for example: Yes with No, Bow with Angry, Shrug with Wave, and Cheer with Yes). The emote responses are different for each player. If you are having trouble determining the correct response, watch the two other spirits nearby who are having an emote conversation. Each time the correct emote is performed, one of the rings around the girl will disappear. If you respond with an incorrect emote, all the rings reappear, and you must start over.

After all the rings are gone, speak to the spirit girl. You will find her very hard to understand. Anyway, she wants to meet you at a village in the mountains to the west. Head to another ruins marked on the map in the westernmost part of the Wilderness, west of the Bandit Camp. Beware of Revenants.

Cleaning the spirit
Talk to the spirit again. She will again not talk properly and mention something like "being stuck", "a beast", "washing something" and "a barrel" (the one she is next to). For this part of the quest you need a rake, a bucket, a watering can, a hammer, 4 steel nails, 2 planks and a seed dibber. All items can be found at the ruins, but you can also go to Varrock and buy them.

The girl wants to clean her face. Next to her there is a barrel, which is filled with water in the real world. Empty the barrel in real world by using a bucket on it. Now enter the spirit world again. The girl can wash herself now.

The girl now wants something to eat. Go back to the real world, west of the patch near the statue, and pick the hollow log to get mushrooms. Return and she will eat that.

The girl then wants you to get some clothes out of the wardrobe she is standing near. Back in the real world, use a plank on the wardrobe with another plank, 4 steel nails and the hammer in your inventory. Go back to the spirit world and she will be able to use the rag to clean herself up.

Next, she wants to retrieve her doll which is buried under the diseased Limpwurt plant. Once again go back to the real world. Rake up the weeds, then search around for a limpwurt seed or bring your own. Plant and wait for it to grow (watering makes it faster). Go back to her world where during the cutscene she will get her doll.

Trapping the Spirit Beast
After this, she will begin to speak normally and ask you to go to the farm, she'll teleport you there if you decide to go immediately. You need to place offerings for the altar to feed off once she shows you where to go. Go back to the real world and pick up a skull and five bones. Bone respawns are strewn around the farm, and there are skull spawns to the east of the farm. Go to the spirit world and use the skull and bones on the altar. Summer will tell you that you must use the power of spirits along with the power of the disks in order to trap the Spirit Beast.

At the northeast corner of the farm will be a disk with a Spirit Wolf on it. Stand just aside this disk and summon a Spirit Wolf. Move yourself so that the spirit wolf moves with you, onto the disk. The beast will approach the first disk. As the beast steps onto the disk, quickly dismiss the Spirit Wolf. If you are successful, a short cutscene will show a new disk appearing. Repeat on the new disk, only this time, summon a Desert Wyrm, and again a cutscene will show a new disk appearing if you are successful. Summon a Spirit Scorpion for the third disk. In each case, you must dismiss your familiar as soon as you, your familiar, and the beast are all on the disc. If your familiar is not dismissed when the Spirit Beast gets too close, it will devour the spirit, requiring you to get another pouch, so several of each pouch may be needed. Therefore, it is helpful to try to position yourself between the beast and your familiar.

After the Beast has had three shocks from 3 different familiars, three spirits (Meranek Thanatos, Erik Bonde, and Jallek Lenkin) appear and seal it at the last disc. Talk to one of the spirits that have trapped the beast to finish. Quest Complete!

Trivia

 * The farming patch where you grow the Limpwurt plant is the only one in the game with a Goth Leprechaun nearby.


 * On the day of release, the spoilers said "Woo... wooo..."


 * On the day of release, Spirit of Summer was not yet on the quest list, but was added 10 minutes later.


 * The Spirit Beast in the quest is an astounding level 717, which surpasses TzTok-Jad as the highest level monster in RuneScape, though the Spirit Beast cannot be fought.


 * Surprisingly, seeing the spirits in the quest does not require the Ring of Visibility.


 * You can get a skull in the spirit world a little east of the farm.


 * After the quest was announced, and before it was released, when walking through the Ruins, you would get the message "Whoo... Whoo... Whooo!" in your chatbox. If wearing an Amulet of Ghostspeak, the message would be somewhat along the lines of "Help... Somebody, please!".


 * This was the first quest that needed a Summoning Level to complete.


 * A bug existed during the quest that would cause your character to still "have a familiar" after it had been dismissed. This was fixed by logging out and in.


 * A bug existed where if your familiar disappeared with items in it, while in the "Dream Realm", then you would be unable to pick the items up.
