Firebomb's Lair

Firebomb's Lair is a hard dungeon but very short. It is required for the Herobrine's House questline. At the enterance, there is a giant room with the Enderdragon spawner. The enderdragon is named Firebomb. Firebomb can destroy the entire floor in that room, so it is reccomended you bring a bow with you and do not fight him near the enterance.
