Minecraft wiki entry for Defeating_a_bastion_remnant, associated text: Regardless of what part of the bastion you're trying to explore, it's a good idea to start exploring from the top and work your way down. Piglins won't hesitate to take fall damage to get to you, which can easily result in you getting ambushed if you start exploring from the bottom. A Piglin Brute landing on top of you is especially deadly, as they can disable your shield, leaving you completely vulnerable to their high damage attacks. Because of this, it is highly recommended to bring at least one Totem of Undying to a bastion remnant.
