Deep in the Abyss

The Burn in Hell quest is one of the hardest quests in RuneScape. It can be started by talking to Dethzorian the Berserker in the Abyssal Crevasse, in Level 80 Wilderness.

After talking to Dethzorian, he will tell you to go to the Portal to Hell in the Zamorakian Dungeon. This will take you to the 1st floor of Hell. In order to get into Hell, you must have full loyalty to Zamorak (can be earned by choosing Zamorak in the Gods Quest.), have done Dragon Slayer, and have a Combat level of at least 100.

Here, you will find Level 49 Hellish Souls. These creatures are not very tough, but do drop keys, which can be used on various door in the area, to get to the 2nd floor, just below floor 1 (marked in Roman Numerals on the main Quest Page). Here, you fill find Hellspirits, all level 70. These sometimes drop Hellspirit Shards, which sell fro 100-500K Hell Tokens each (Hell Tokens can be used to buy full Dethzorian armour, for 500M Hell Tokens). After a few kills, a Hellish Orb should drop. Use this on the portal, and it should turn from Purple to Red and Black. Enter the Portal to get to the 3rd floor of hell. This level is one of the hardest. You will find a group of level 126 Hell Masters, the Torture Masters of the Underworld.

From here, you need to kill them until they drop an orb, which has the same purpose as the orb in Floor 2. (these monsters, on occasion, drop Large Hellspirit Shards, worth about 1M Hell Tokens each). From here, you will be teleported to floor 6. This is the hardest yet. These are the level 726 Corporal Beasts. These drop Hellspirit shards worth 10M each, and also Dragon Plate Armour pieces. After you get the Hellspirit Key, use it on the door, and you will spawn in a room with a level 1000 Helldragon. This beast can hit up to 9000, so you better have at least Vorneshurn armour on.

After killing it, you should then be rewarded with a Dragon Kiteshield, worth 9 Billion gp.
