Regicide

Starting Out



 * After receiving the King's message, go to King Lathas. He will tell you to go through the Underground Pass again to the western Darklands. You must talk to King Lathas before entering the Underground Pass, even if you are sure you have already started the quest!
 * Make sure you have everything you need before setting out on the trip. If you reach the Elven lands and realise you have forgotten something, it is a long way between the bank and the quest areas, even with teleports. Before going into the Pass, you should have:
 * 2 ropes - one for the Pass and one more in case you fail crossing the first time (There's a rope spawn in the dungeon to replace ones used/lost.)
 * A spade
 * Bow and arrows (Note that broad arrows don't work!)
 * Weapon and armour to kill a Tyras Guard
 * Optional:
 * Antipoison (4 doses) or Prayer book (from The Great Brain Robbery) with blessed Holy symbol (recommended)
 * 3200 coins for the charter ship from Port Tyras (recommended)
 * Good food (depending on level, for the battle with the guard)
 * Agility potion or Summer pie. If you are 51 agility, it is reccomended to bring two or three summer pies, just to be safe.
 * Hatchet and tinderbox for cooking food, as Barbarian Firemaking does not work here. There is a fishing spot at the river near the Elf camp, where one can use Bait or Lure fishing along the river, and north-west of the elf camp is a Big Fishing net/harpoon spot for sharks.
 * Plank (you can choose to disarm the floor traps or you can pick up the plank that spawns in the dungeon)


 * You will not need to do much from the Underground pass quest again. You do need to go through the dungeon, including shooting the rope to get through the bridge and going through the obstacles. You do not need to collect or kill anything. Do not talk to the paladins or they will attack you. See the separate guide for instructions about how to get through the pass.
 * To get to the Well of voyage, go to the chamber where Iban was. (Bug: From the outside it looks like he's still there, but he's not.) Once there, you can talk to Koftik to get a bowl of Stew and two loaves of Bread, if you need them after the traps.
 * Climb down the Well of Voyage. The cave has an altar and a Summoning Obelisk. The cave exit is at the western end.



This is the whole map of Tirannwn with a useful legend and track. You should refer to the map above for reference to prevent getting lost.

In Isafdar

 * Go out the cave. You'll meet with Idris on your way westward, but Morvran and Essylt will quickly shoot him down. They will tell you to talk to Lord Iorwerth, who can be found at the camp in the north west corner of the forest.
 * Make your way to the elf camp in the north-western corner of the forest, remembering that you can not yet pass through dense forests. Lord Iorwerth will tell you to talk to his Tracker after you tell him that King Lathas sent you.
 * On the way, you will encounter four different obstacles:

Dense forest
You need level 56 Agility to navigate through dense forest. You cannot get through until later in the quest when an Elf Tracker teaches you how. Dense forest cannot be failed and it acts as a shortcut inside the forest. It's also the only way to reach some areas. On the way into Tyras's camp, you need to boost your Agility level if it is not 56, but you won't on the way out. You only need the boost for the first of the 3 dense forests. For example, you boost to 56 and get through the first dense forest. Then your Agility goes down to 55. You can still go through the second and third dense forests.

Leaf trap
Leaf traps look just like trees from above. You will see some leaves on the ground. If you step on them, you'll fall into a pit and lose 150 life points. The trap has two sides: your side and the other side. Click "jump over" on the same side of the trap that you are. Still, You may fail.

Tripwire
You will see two rocks very close together. There are also four miniature crossbows pointing at them. Move your cursor between the rocks to find a tripwire, then step over. If you trigger the trap, you'll be hit double 50s and get a ~20-damage poison condition.

Stick trap
You'll see some sticks on the ground in a formation similar to a hurdle. These are stick traps. Right-click "pass" on them. You will almost always fail. If you do, you'll lose 80 points.

Finding the tracker



 * Go south-east of the camp until you find an Elf Tracker. He is due east of Tyras Camp in the map. He won't believe you since you're a human, so return to Lord Iorwerth to get a crystal pendant. Put it on and talk to the Tracker again. He will tell you to find the Tyras Camp.

Finding Tyras' camp

 * Check the footprints to the west leading into dense forest. You are told that you see no way past, so go back to the Elf Tracker, and he tells you what you need to know to pass. You can now climb through if you have level 56 agility.
 * When you emerge from the dense forest, a level 110 Tyras Guard, equipped with a steel halberd, attacks you. He has a very high defence and life points and can hit a maximum of 150. He is somewhat easy to defeat with Protect from Melee and a decent weapon or magic. Be aware that there are not many "safe spots," and his halberd can reach over most of them. There is a ranging or magic safe spot behind the mushrooms to the west, giving two spaces between you and the guard. It is also possible to get outside of his wander radius and safespot him from there.
 * After you've killed him, continue on to the Tyras Camp. Talk to General Hining. Be sure to grab a barrel while you are in Tyras Camp. It is possible to charter a ship from Port Tyras, just south west of the Tyras Camp, even if the player doesn't want to talk to Hining. It is wise to charter a ship now and then come back immediately, especially if the player has less than 56 Agility.

Back to the elves



 * Go back to Lord Iorwerth. He gives you the Big Book O' Bangs. Read it. You need to make an explosive compound. Grab the Empty pot from his tent, if you need one.
 * Making the naphtha can be prone to error. Each time you start the process, you need a barrel of coal-tar. Wear gloves when you collect the components or you will take damage. A Regen bracelet prevents damage as well. Other bracelets may also prevent damage. A Combat bracelet, though, does not.
 * Go south of the Elf Tracker until you find a poison waste swamp. Use the barrel on the poison waste to get a Barrel of coal-tar.
 * Break off a chunk of sulphur, which surrounds the area.
 * (There is a glitch when you try to get the tar with the barrel sometimes. Just drop the barrel and pick it up again and it should work.)

Making the explosive in Rimmington
This part has a video for it can cause confusion, Click Here to View it


 * Teleport out of the elf kingdom or take the charter ship out of Port Tyras. Chartering a ship from Port Tyras allows you to charter a ship to Port Tyras to return, avoiding the agility obstacles in the dungeon when you have a heavy bomb in your pack.
 * Withdraw about 10 or so coal from the bank
 * Go to the Chemist's House near Rimmington and talk to the Chemist with the Big book of bangs in your inventory.
 * Use the barrel of coal-tar with the Fractionalizing still.
 * To operate the still
 * Click the right side of the valve to the right twice, so the tar should be flowing at maximum. You should see the 'pressure' indicator on the left go up.
 * When the pressure indicator reaches the green region, click the right side of the valve on the left once to let out pressure. This should stall the indicator on the left.
 * Start adding coal. This raises the indicator on the right. If it's below the green region, add more coal. If it's above, don't add coal until it gets lower.
 * The bar on the bottom should start turning green. When it's full, you can stop adding coal and close the window on the top right to get your barrel of naphtha.


 * Take an empty pot with you. While wearing gloves, use a bar of limestone on any furnace( note: super heat will not work). Quicklime should be formed. If you heat the limestone without wearing gloves, it could damage you up to 80 life points. Lunar gloves will not protect you from damage.
 * Use pestle and mortar on the quicklime to get a Pot of quicklime. Add the pot of quicklime to the naphtha.
 * Grind the sulphur with your pestle and mortar to make Ground sulphur. Add the ground sulphur to the barrel, making the Barrel bomb.
 * Use a strip of cloth on the bomb. If you didn't weave your four balls of wool yet, go to the loom at the Falador farming patch and do so.

Return to Tyras Camp


Remember to take a tinderbox! Using Barbarian Firemaking does not work. If you forget a tinderbox, the Quartermaster at the Tyras Camp sells one.


 * Now that you have the barrel bomb, return to the elven kingdom. If you go through the Underground Pass, remember to bring a spade, ropes, a bow, arrows, and a plank. If you used the charter ship out of Port Tyras, you can just use a ship to get there again for (at most) 3200 coins.
 * If you still need a cooked rabbit, kill one in the area in which the Elf tracker is found. Cook it on a fire in the Elven Camp or light one on the ground.
 * Go to the catapult outside the Tyras Camp. Give the cooked rabbit to the non-armoured Tyras guard near the catapult to distract him.
 * Use the barrel bomb on the front of the catapult. You do not need to light it first, but you do need a tinderbox in inventory. A cutscene plays showing the destruction of Tyras' tent and an unidentified body (presumably Tyras) within.
 * Go back to Lord Iorwerth. He gives you a letter to take to King Lathas, then gives you access to the overland pass of Arandar. Make sure you have the letter before leaving or you will not have the use of the overland route.

Return in triumph?



 * Take the overpass or teleport away, then go to Ardougne Castle. On the way, an elf named Arianwyn will break the magic seal on the letter and tell the player to read it. In the letter, Lord Iorwerth told King Lathas that Tyras was killed and that some dark lord could be resurrected to take over Camelot. Arianwyn further revealed the "path" being connected to Zamorak's realm, and recruits the player to their side instead. Even so, Arianwyn tells you to talk to Lathas first for your reward.

Reward

 * 3 quest points
 * 13750 Agility experience
 * 15000 coins
 * Access to the elven kingdom and the overpass of Arandar
 * Access to Port Tyras by Charter ship
 * Access/ability to wield the Dragon halberd with 60 Attack and 30 Strength.

Trivia



 * The name of the author of the Big Book O' Bangs is "Mel Achy", an anagram of "Alchemy".
 * Since 1 July 2008, after the Runescape HD Graphics Update, some players have had trouble with the Fractionalizing Still at the Rimmington Chemist. Whenever these players attempt to distill the Barrel of Coal-tar, turning valves and adding coal, no progress is made whatsoever. Jagex has yet to fix this bug. Anyone with this problem cannot complete Regicide. However, some players have been able to distill their tar without any problems. Some who couldn't distill their tar while playing in HD were able to do it by playing in the old detail modes.
 * The substance in the barrel bomb has a real life parallel, Greek Fire, which ignites on contact with water and is very hard to put out once it begins to burn.
 * Naphtha was used in Mongol Siege Warfare in the time of Genghis Khan. It is thrown by a catapult and it catches fire when airborne.
 * After completion, reading the quest journal will reveal nothing but simply stating that the player has done the job, similar to Underground Pass
 * Hostile Spawn, a game on Funorb, has a similarly-named level.
 * There is a glitch where 4 Arianwyns may spawn for one single player. It is unknown whether this has been fixed or not.
 * The quest description mentions the word serene. This is a reference to the Elf Goddess, Seren.
 * Even if you are in a non-member's world, you can still receive the king's message after completion of Underground Pass.
 * There is a glitch where even after regicide is started, when outside Iban's throne room it appears that he is still there, and appears to be fighting someonne, you see him yelling what he does when you fight him and see the spell happening, but upon entering the room, however, it changes to the well of voyage being restored. This has yet to be fixed.
 * Players unlock 10 music tracks throughout the quest, which is the most for any quest.
 * Regicide is the act of killing a monarch, which is done in the quest.
 * If you speak to a Tyras Guard at Port Tyras, their face will be hidden from their helmet. However, talking to a guard at the camp, you can partially see the guard's face.
 * When crossing the leaves, you can get glitched and stuck into the ground.
 * If you try to talk to Arianwyn again after the conversation you will get the message "Nothing interesting happens."
