Heart of Stone

Heart of Stone is the first quest in the Elder God quest line. It involves Xenia, a well-known hero who has gone mad, stealing a spell to bring the Abyss into Gielinor, and it is up to another hero to stop them, with the aid of a rune golem created by Ariane. The quest leads the heroes through sites connected with the Elder Gods, and is the beginning of unlocking their mysteries.

Conflict with Ariane and Xenia
To start, interact with Xenia and Ariane outside of the Wizard's Tower. Accept the quest and a cutscene will occur where Ariane is not letting Xenia pass because she has murdered Corvusa, an innocent man.

Pick either option (side with Ariane, Xenia, or break them both up). The choice does not matter, but it does have an effect on the golem later in the quest. Xenia finally stops Ariane, and teleports away.

Tracking down Xenia
Meet Ariane at the Old Tower, east of the beginning of the quest. She will explain that you need to track down Xenia with her, using the help of the Kinaethetic Investigation Programmable Personality Lifeform Emulator, or Kipple. Kipple is designed to adapt to any challenges it faces, and will be used to track Xenia down.

Talk to Kipple and use the Runic Frequency Modulator. The basic idea of The Runic Frequency Modulator is to rotate discs to find a frequency, which is indicated as a red dot bouncing up and down on the chart - right side of the display screen. Once the signal is found, you'll have to rotate the discs to fit the height of pillars to match with the height of frequency in each position. The chart corresponds to the values the runes on each wheel are in. For example a fire rune in the outermost circle (1 point) plus a fire rune in the innermost circle (3 points) equals a value of 4 on the chart.

Find a match and follow the signal. There are four signals altogether, each leading to the location of an Elder God (Note, Mah is not included): Karamja (Ful), White Wolf Mountain (Wen), Entrana (Bik) and the Kharidian Desert (Jas). When you get to each location, Kipple will appear and ask you to re-tune him to locate the portal.

Entrana
It is suggested for low level players to take some food along to Entrana, as you'll have to fight level 35 enemies. Travel towards Entrana through any means. Kipple will be joining you at Entrana and will follow you like a familiar would. The portal is located on the north-western side of island. Kipple will inform you when getting closer to right spot and you'll have to tune him to open the portal to Bik.

After tuning the correct frequency in Kipple a portal will open. Enter the portal and try opening the Bik door. Kipple informs you that you have angered the Bik and there will be enemies around. Kipple will provide you 3 weapons for each combat style; air battlestaff, bronze dagger and a chargebow. You will be attacked by BikKra's attendants and unstable attendants, the point is to lure these unstable attendants near Kipple, so it can disarm and place them next to the Bik door. When there are total of 3 unstable attendants placed next to Bik door, light them up to blow the door open. Talk to BikKra, who speaks for Bik, an Elder God. Speak about Xenia, then select the option addressing BikKra as "the mighty one". He will then talk about Xenia and her business around BikKra's cave. After talking with BikKra, talk to Kipple, to track down the next place.

Karamja

 * Combat equipment is recommended for this part.

Travel towards the Karamja Volcano and tune Kipple's tracker to find the portal, just a bit south from the entrance of TzHaar. Once you have done this, enter the portal and dialogue with FulKra will appear. Kipple will try to debate with FulKra, while you have to fight level 44 FulKra's attendants. They can be killed easily with any combat style. From time to time, fire will spring up from the ground and harm the player. Simply step out of the way to avoid damage. It is advisable to use range or mage at this part in order to avoid the fires that spawn underneath the player.

After a few minutes, Kipple will finally have finished debating. Talk to FulKra, and respond with any dialogue options. After speakin with FulKra it is time to tune Kipple's tracker to find the next portal.

Kharidian Desert
East of Sophanem, combine the memories on each other and then use them on the statue. You need 20 free inventory spaces for this puzzle. Only use the memories that are related to the quest. At a certain point, you will have to combine 2 combinations of memories.

Combine:


 * Correction with Transition.
 * Dispersal with Arrival.
 * Evolution with Imprinting.
 * Predator with Focus. (Corruption and predator are combineable but no use)
 * Theft with ERROR.
 * Revelry with Silence
 * Conflict with Condemnation.
 * Golem and I with Ariane and the Golem. Combine the two combination pieces.

There are two other combinations that serve no purpose in convincing. After combining the memories, use all of the combined memories on JasKra to trigger new dialogue.

White Wolf Mountain
Run to the middle part of the mountain, west of Taverley lodestone and retune the tracker to make a portal visible. This portal will teleport you to an ice chamber where you have to solve a power puzzle. Each beacon gives or uses certain amount of power. You need to match the number of power activating or deactivating correct beacons. After solving all 5 puzzles you will be able to speak to WenKra, the voice of Wen.

Lumbridge
The final portal is in Lumbridge at the cemetery. This is were you will have to fight the final boss, prehistoric abyssal.

As soon as you enter the portal, a cutscene will start with Xenia kneeling in front of what looks much like her portals. She will turn to you and mention how she was expecting you, but is surprised you were so slow in following her. She will explain to you what she has been doing, why she has been stealing the energy from the voices of the Elder Gods, and why she is doing this. Xenia will go on to explain that she too has seen Freneskae for what it is, and believes the Elder Gods caused it. Ariane herself appears next to you and confronts Xenia. As it turns out, Xenia herself is referring to the Great Revision, the idea that the Elder Gods will eat all the Anima off of Gielinor and destroy all life on it. Xenia is therefore trying to drain the Anima herself, preventing the Elder Gods from awakening, but Ariane argues that there we be no magic left on Gielinor. Eventually, whether you agree with Ariane, Xenia, or neither of them, Ariane will proclaim her intention to kill Xenia, which Xenia does not believe. another cutscene will occur, in which Ariane will blast Xenia into the abyss, killing her. The prehistoric abyssal will then appear and announce that thanks to Xenia, the awakening of the Elder Gods has begun. The battle against him then begins.

First you will need to get rid of his defensive layer. From time to time, it will summon a glowing red ball, which will hit you for up to 1000 hitpoints. Try to get Kipple between you and the ball. Doing so will start Kipple to detect energy. When he is done, an abyssal anchor will spawn and you need to destroy it. Do this 3 times and the actual battle will start.

Magic is strongly adviced for the fight, because it has a weakness for air spells. It's not recommended to use ranged, because any ranged damage dealt to it is significantly reduced. If you have a decent magic and an inventory of food, the fight isn't that hard. Its base attack is melee. It also has a special attack, which you can recognise as a blue bar (like the adrenaline bar) will show up. Once it is full, he will release a special magic attack, possibly hitting up to 2000+. You can avoid this just by running away far enough (3x3 target area). At a certain point, he will throw you away, stunning you for a second, and immediately start charging his special attack. Fairly easy to avoid if you start clicking to run away once you have been thrown away. Once he reaches about 2500 hitpoints, he will start using ranged attacks and also his special attack (about every 10 seconds). Just keep running away from his special attack and use protect from range if necessary.

If you happen to die at the same time as the prehistoric abyssal, you can continue on to Ariane at the Wizards' Tower. (Check quest journal)

Finishing up
After the final fight, speak to Ariane to finish the quest. You can discuss more about Xenia with her. Additionally, you can ask her about each of the Elder Gods, including Mah, whom Ariane doesn't know much about. She will give you the reward and tells you to come speak to her at the Wizard's Tower (to get your Kipple Nano pet).
