Minecraft Living Ep 183 (Wither Skull Farming)

This is my main survival world (started as Hardcore). Going to be trying to get all the major achievements with killing the Ender Dragon last. So what the main goals are: diamond armor enchanted, elytra, full beacon, discover every biome, complete a raid, empty a bastion, empty a woodland mansion and ocean temple, full enchanted netherite, full enchanted trident (both types), and of course, kill the Ender Dragon. To do my goal, I will need to die at least once. The plan is to get the elytra and put it in an ender chest, then return to the overworld without killing the dragon. Currently: just trying to get wither skulls... and not having luck ;(
