Go back to town and prepare for a battle. The RS gold Sayaniona's are a hybrid of a Greater Demon and a Pyrefiend. However, don't forget about the uni-horn that is on its head! They are Level 90, and are hit as high as 14 times, and be able to attack your prayer with their special strength. If your strength is lower than 60, it is an ideal idea to have at minimum two prayer potion and a super-stength pot.
The Sayaniona's reside located in the forest in the northwest region of Solar Isle. Go back to the hut, where the cheif lives. Return to the hut behind then climb up the rockslide then return to the bolders. The boulder will be broken if you use the grapple. Then, use the rope with the boulder and attempt to pull it. The boulder will fall and roll back towards you. Attach the hook back to your rope, and then swing it around the boulder. (Requires 55 Agility).
You'll be escorted into the Sayanionas' lair. They are aggresive, and they will swat you. Go past the room full of Baby Sayanionas that are in the levels 25 and above. They're useless at the moment. Go past the Lesser Sayanionas, until you get to a room that has Greater Sayanionas. These are level 90, and will be hard to eliminate. Keep your Guard against Melee alive and fill it up with prayer pots. Take the horn after it has died. Grind it up with mortar and pestle. It will be ground Sayaniona’s Horn. The next step is to extract the water.
Go back to the village on Solar Isle, and go to the Cheiftain's house. One ladder goes up and the other goes down. Take the ladder down, and grab the pile of rubble. Click rub the rubble to gain an Enchantment Rock. Pick up a pickaxe to take magical dust from the chest at the west end of the corner. Keep climbing up the ladder, and then go up the second ladder. Fill the vial with Water of the Ancients. Add the magic dust, and you have the vial of Magic Water.
You must now mix your herbs according to the directions on the scroll. Three Sunbleached herbs and one Sunset Herb. Ground Sayaniona's Horn. You will receive a vial of Enchanted Posion. Utilize it in conjunction together with the Sunrisen Staff. A Solarus Staff will be given to you. This is the only weapon that you can utilize to take out Ethernals. Go back to the Cheiftan.
Did you design the weapon used to take out Ethernals Yes, I've done so. Excellent. Follow this map, and return to me using the staff of the Ethernal. Follow the map and you'll arrive at the frozen trapdoor. Utilize the Solarus Staff with it, and the trapdoor will be opened.
