You will want full enchanted diamond armor, along with enchanted diamond tools and a sword. You should also bring along a bow, arrows, blocks, golden apples (enchanted if possible) or potions of fire resistance, an elytra, fireworks, a hopper to loot chests, one piece of gold armor, a lava bucket, food, and multiple shulker boxes. Having a good shield and regenerative items are always a good idea for this situation. [1] X Research source
Make sure to equip your gold armor, as this will prevent Piglins from attacking you. [2] X Research source
Bastion Remnants can spawn in the Crimson Forest, Nether Wastes (the only biome pre-1. 17 Nether), Soul Sand Valley, and the Warped Forest.
You can always loot the chests without a hopper, but beware of any Piglins that may backstab you.
Enchanted Golden Apples also work, and will also provide you with Regeneration, Resistance, and Absorption along with the five minutes of Fire Resistance
