For some reason not enough people use ender chests and it doesnt make sense to me. Like bro u have 27 fully safe shulker boxes in there that u cant lose. I for one have 1 firework shulker, 1 armor shulker, 1 gear shulker, 1 food shulker, 1 stick and coal block shulker cuz i need torches in the most random times and sticks are useful. And then everything else is just junk i place in there. Like i have a storage system where i just pull out all 22 junk shulkers and completely empty them and then im free to have 22×27 deportable slots that i cant lose. I also used to fly in the nether with iron armor and elytra. If i find a bastion i pul out my ender chest and get my gear if i die cuz i cant fly in the nether i only lost 1 diamond-netherite pick and an elytra
Mumbo knows about ender chests. He just doesn’t care. His play style isn’t really one that requires him to have access to all his stuff anywhere on the server.
