Dragon Slayer is a free-to-play quest. This quest is regarded as the most difficult for free-to-play players.

Details

Walkthrough

Talk to the Guildmaster in the Champions' Guild, and ask him for a quest. He will then tell you to visit Oziach, who is located in the north-west corner of Edgeville, very close to the Wilderness. Oziach says that to be able to buy a rune platebody from him, you have to kill the green dragon, Elvarg, located on the desolate island of Crandor.

Return to the Champions' Guild, and talk to the Guildmaster again. He will be shocked and will tell you that you will need to obtain three pieces of the map to get to the island, a boat to reach Crandor, and a shield to protect yourself from the dragon's fire.

Important: You must ask him every question you can; otherwise, you won't be able to progress in the quest.

Ask him where Melzar's piece is to obtain the maze key (must have open inventory slot), and make sure you ask him where the maps are and where to get an anti-dragon shield.

Note: To save time, make sure you talk to the Guildmaster about buying a boat (ask how you can get to Crandor and where to get a ship) before you go see Klarense in Port Sarim later in the quest. This will save you having to walk back to the Guild after collecting the map.

Obtaining the anti-dragon shield

A free Anti-dragon shield may be obtained by speaking to Duke Horacio in Lumbridge. He is located on the 1st2nd floor[?] floor of the castle, in the northern room. Alternately, you may purchase a shield from the Grand exchange very cheaply.

Obtaining the map pieces

These map pieces may be obtained in any order. When you have all three, use any piece on another piece to form the complete Crandor map.

Melzar's map piece

The first piece is found in Melzar's Maze. You will need food if you have a low combat level. Melzar's Maze can be found north-west of Rimmington, south of the Crafting Guild, and west of Port Sarim. (If your house portal is located here, you may wish to teleport to house and exit portal.) To get inside of Melzar's Maze, you must use the key you get from the Guildmaster in the Champions' Guild when you've started the quest. Once inside Melzar's Maze, do the following:

Thalzar's map piece

Items required: An unfired bowl, a wizard's mind bomb, a lobster pot, and silk.

To obtain this piece, you'll need an unfired bowl, created in the Crafting skill, a Wizard's mind bomb, which can be bought in Falador for 3 coins, a lobster pot, which can be bought in Port Sarim for 20 coins, and a piece of silk, which can be bought in Al Kharid or stolen from a silk stall with level 20 Thieving. When you have all these items, talk to the Oracle, who is located on the northern end of Ice Mountain.

Then, when the Oracle is done talking, go into the Dwarven Mine with all those items. Look for a magic door in the northeastern part of the mines. It is just before you see scorpions. When you've found it, you must use all of your items on the door to open it. Open the chest and search for the second map piece.

Note: Placing the wrong items into the door or putting some in, leaving, then coming back, and putting in the rest of the items will not cancel out the items already placed in the door. Be careful not to left click your Wizard's Mind Bomb, as you will consume it rather than use it.

Lozar's map piece

Items required: 10,000 coins or Ranged/Magic combat equipment, an air rune and a law rune (33+ Magic required).

The third and final piece can be obtained by talking to Wormbrain. Not Required: You can make your way to the Goblin Village and talk to the General who will tell you that Wormbrain has been arrested and is located in the jail in Port Sarim. Use one of two different ways to get the map piece from Wormbrain, located in Port Sarim Jail.

You can attack him using Ranged or Magic. Once his health reaches zero, he will say "Ow!" and drop the map part for you to telegrab (if you bought an extra Wizard's Mind Bomb, you can drink it to boost your Magic level +2).

Ranged or Magic. Once his health reaches zero, he will say "Ow!" and drop the map part for you to telegrab (if you bought an extra Wizard's Mind Bomb, you can drink it to boost your Magic level +2). Wormbrain can be attacked and will drop his map piece whether the player has spoken to the Goblin General or not.

Alternatively, you can pay him 10,000 coins in exchange for it.

With all three map pieces, simply use two together, and they will all combine into the treasure map.

Obtaining a boat

Items required: A hammer, the Crandor map, 90 steel nails, 3 planks, and 2,000 coins.

Note: You will need to talk to the Guildmaster about buying a boat before you go see Klarense, but only if you haven't asked him already.

You will need 90 steel nails and three planks. To obtain the steel nails, you can either smith six steel bars into nails (requires level 34 Smithing, which is boostable), or you can buy them from the Sawmill operator north-east of Varrock or from other players. If you are a free to play ironman, the only place to get planks is at the Graveyard of Shadows in level 19 Wilderness. Next, get a hammer and 2,000 coins. Go to Port Sarim and look for Klarense, a sailor. He is located on the second-most southern dock. He will sell you his boat named Lady Lumbridge for 2,000 coins. Pay him the 2,000 coins, and the boat is now yours. Go on the ship and go inside it. Repair the hole in the ship by using the planks with the hole.

Note: If you forgot your hammer, and are on a members' world, you can buy one from a Trader Crewmember on the dock to the south, travel to the Void Knights' Outpost and buy one from the general store, or you can attack the goblins to the west until one is dropped. If you are on a free world you can kill goblins west of Port Sarim until they drop a hammer.

Do this three times, and the hole will be repaired. Next, go to Draynor Village and find Ned, the person who makes ropes for you. Ask him to be the captain and help sail you to Crandor. Make sure you have the Crandor map in your inventory, or you will need to retrieve it from your bank. He will agree and tell you to meet him on your ship.

The fight

Items required: Food, combat equipment and the anti-dragon shield.

Now, it is time to prepare. Equip the Anti-dragon shield, some armour, and a weapon. Elvarg is weak against stab attacks, so consider bringing a sword or dagger instead of a scimitar. Adamant or better is recommended. Elvarg is also weak against Ranged Attack, so Rangers should bring their best crossbow with the best bolts they can use. Elvarg is not immune to poison, so adding weapon poison will make the battle go much smoother, thus a p++ dagger would be superb. The rest of your inventory should be filled with food; lobsters or swordfish should do. Swordfish are preferable to lobsters since they heal more per bite (14 vs 12), but with a combat level of around 40 and appropriate gear, you should be able to easily defeat Elvarg with just lobsters. If your stats are lower, you can buy or cook meat pizzas or anchovy pizzas with level 45 Cooking to bring as they heal more Hitpoints per inventory slot, but require a second bite to consume. A meat pizza heals 8 HP per bite (16 total) while an anchovy pizza heals 9 per bite (18 total).

Go to your ship and sail to the island Crandor. After crashing on the island, make your way through the island to the top, avoiding the monsters there. You'll see stairs behind some lesser demons. Run past them, and enter the hole. You'll be in a cave surrounded by skeletons. Keep walking and you'll see Elvarg behind a door in a room.

Before you enter the room, make sure that your anti-dragon shield is equipped. Also, if you go south a little further past the lesser demons, you should see a wall with an open option. Push it to go through and unlock a shortcut back to Elvarg in the event that you die or teleport away. Now, go in and fight Elvarg.

Battle strategies

Note: You can return and continue the fight if you die, as well as pick up your items. But when returning you can use the amulet of glory to Karamja and go down the volcano to return to Elvarg quickly, If you have opened the secret door before the fight. If not you must refix the boat and return with Ned again.

Consider having Protect from Magic activated, as Elvarg's Fire Blast-like magical attacks hit high. Again, using a stab weapon like a dragon dagger (p++) is a good idea since dragons are weak to stab. If you also use Ranged on the dragon, make sure you are using a one-handed weapon such as a crossbow, unlike a bow, which is two-handed. With a crossbow, you are still able to equip the anti-dragon shield necessary in the quest.

If you are using magical attacks, make sure you are using tier-2 Magic (i.e. Bolt spells such as Wind Bolt, Water Bolt, etc.) or higher and can equip the anti-dragon shield. Also, bring teleportation runes just in case you are about to die.

It is important to note that if you use an anti-dragon shield, as well as a drinking a dose of antifire potion, Elvarg can only hit a maximum of 7 (3 or 4 if combined with Protect from Magic) with her magical attack instead of 11, thus saving you a lot of food.

If you are around 35 Defence, or more, it may be advised to stand next to Elvarg, rather than safespotting, as her mage hits can easily outweigh her melee hits. It is also advised to stand under her while you eat, as it will save food by not getting hit whilst you can't hit.

Lower levels and iron men without antifire potions are advised to use a ring of recoil, as Elvarg's fast hits make it particularly useful in dealing back damage.

Also, Elvarg can be flinched using melee attacks. This is fairly easy for players who know and practiced flinching before, to the point where it takes almost no food to kill her. For players who don't know what flinching is, it is still recommended to take a lot of food, as getting her in the right position is quite tricky. You need to stand in the southeastern corner of her cave, in the square directly next to the top-left corner of the little lava pool, and you need to get Elvarg to stand directly left of the skeleton on the ground to the northwest. If you pull this off, you will notice she does not use melee or magic attacks, while you're standing on the square mentioned above. From there, you simply attack her, and immediately click on the top-left corner of the little lava pool again to walk back to the safe square (as there are often rats occupying the actual square). Wait for her health-bar to disappear and repeat the process. As this can and will still go wrong every now and then, it is still recommended, but not strictly necessary, to bring food and have a decent combat stat (30+).

If you die or teleport away, you will need to repair the boat again, unless you open the shortcut. If you did open the shortcut, you will not be able to travel to Crandor again by boat. You must use the entrance underneath Karamja Volcano.

If you happen to teleport away, Elvarg will not heal if you go back quick enough. So, if you get her down low enough and leave, she will still be injured, making her much easier to kill the second time around.

Finishing up

Once Elvarg is defeated and you have triumphed, you will automatically collect Elvarg's head (make sure you have an empty inventory slot). Either teleport out, or go through the shortcut and past the deadly red spiders, to the south east of the dungeon where the skeletons are, and climb up the hanging rope to arrive on top of Karamja volcano. From here, journey to Edgeville, straight to Oziach with Elvarg's head in order to prove your feat (although the head is not required in order to complete the quest).

Rewards

Trivia

When speaking to Oziach at the start of the quest, he asks you how you found out he sells the rune platebody. If you reply 'I am a master detective,' and have completed the Murder Mystery quest, your character will exclaim that they even solved the Sinclair murder mystery all by themselves.

Murder Mystery quest, your character will exclaim that they even solved the Sinclair murder mystery all by themselves. When speaking to Duke Horacio during The Lost Tribe quest, Sigmund mentions to him that you are the same adventurer who defeated Elvarg.
