Nature Spirit

Starting out
Items required: No food (Ghasts rot food if you don't have a Druid pouch), Ghostspeak amulet, a Silver sickle (If you don't plan on making it later on in the quest). Drezel will give you three meat pies and three apple pies to take to Filliman Tarlock. He'll warn you about ghasts that will rot your food. Do not worry about this since you don't actually end up giving Filliman the food. Go south-east after exiting the temple. Note: You must enter Morytania through the gate, or Filliman will not appear. Ignore the warning and go through the gate to reach the swamp. Go south along the west river until you see the grotto tree. WARNING: You will find ghasts in the swamp, which are barely visible spirits that will attempt to rot your food. They often miss, and if you run out of food, they will hit damage on you. You also lose about 3 health at random times when in the swamp. This will not happen on Filliman's island or in Filliman's Grotto. Jump across the broken bridge to the grotto. You may lose upwards of 7 health trying to get across this.

If you try to enter the grotto (only the small black hole in the grotto tree has the enter option), Filliman Tarlock will come out.

It turns out that he has died and is now a ghost, so put your Amulet of Ghostspeak on and talk to him. If you don't have your Amulet of ghostspeak on, he'll say something ghost-like and that will be the end of the conversation. He won't believe that he's dead, so take the washing bowl off the nearby table to find a mirror underneath. Take the mirror and use it on him. He will now believe that he is ghost. After this, he tells you to find his journal. Search the grotto tree to get it and give it to him.

Filliman will tell you that he wants to become a Nature Spirit, but he needs your help to complete the transformation. He will give you a green card that you can use to cast a Bloom spell.

Collecting the three items
Items required: Druidic spell (Given to you by Filliman)

You now need to obtain the following three items:

Something with faith
Go back to Drezel and ask him to bless you. After he has blessed you, he will say: "when I look at you, there does seem to be something of the faith about you."

Something of nature
After Drezel has blessed you, using the Druidic spell and with the Silver sickle equipped, find a rotting log in the swamp and cast the spell next to it to make a mushroom grow. Pick it and show it to Filliman, and he tells you that the mushroom is Something of nature.
 * Note: DO NOT drop the used spell, as you will need it.

Something of the 'spirit-to-become' freely given
The used spell card is the Something of the spirit to become freely given.
 * Note: If asked before placing the items on the stone, the player can receive another unused spell card, allowing them to cast the spell in the next step without using Prayer points.

Now, you need to go back to Filliman's camp, and use the mushroom on the light-brown stone and the used spell card on the grey stone. Then, while standing on the orange stone, tell Filliman you think that you have solved the puzzle. Filliman will complete half of his transformation and ask you to come inside the grotto. Go inside, and search the grotto in the middle of the cave. Filliman will turn into a Nature Spirit. He will then ask you to get a Silver sickle. Give Filliman a Silver Sickle. He will bless it, give you back a Silver sickle (b) and tell you that you can bless other sickles in the future simply by dipping them in the grotto water. He will give you a Druid pouch and tell you to kill three ghasts.

Killing the Ghasts
Items required: A weapon, druid pouch, and prayer points (the more the better).
 * Note: You can use the druid pouch on a ghast nearby to manually make the ghast visible and attackable if it takes too long to get them to do so automatically.
 * 1) Go into the swamp with the blessed silver sickle, and operate it to cast Bloom while standing next to logs, bushes, and twigs. This will deduct Prayer points and will allow you to harvest pears, fungi, and stems.
 * 2) Add at least three pears, fungi, or stems to your druid pouch by clicking "Fill" while three of them are in your inventory.
 * 3) Then, when ghasts attack you, they'll become visible (level 30), and one charge will be deducted from your druid pouch. Kill three of them, and then talk to the Nature Spirit again. He will redecorate the grotto and reward you.
