I went to the end to fight the ender dragon. All enchanted diamond everything. Potions and lots of golden apples. Destroyed all the crystals. Had done damage to the ender dragon already about 2/3 his health when all of a sudden I’m knocked into the air by nothing and taking damaging non stop until I die, about 2 seconds in real time. I went back over ten times to collect my things and keep trying and it happened every single time. There was multiple times I was instantly killed before I could even touch the Ender dragon. Now I’ve lost all my things and there’s no possible way for me to beat the dragon.
