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