Minecraft wiki entry for Ancient_Debris, associated text: This method utilizes the fact that beds, when used in alternate dimensions, explode with a larger blast radius than TNT. It is easy to do, as you don't need to mine a lot. You will, though, use up many beds, requiring reliable wool and wood resources. Furthermore, given the extremely large amount of damage bed explosions deal and the presence of underground lava pools, it may be advisable to bring Totems of Undying, Armor enchanted with Blast Protection and Potions of Fire Resistance to protect yourself. However, these are not required.
