you can’t beat the dragon on peaceful at all- going to the End requires blaze powder, which can only be obtained by killing blazes, which won’t spawn in peaceful mode (okay okay TECHNICALLY there’s a very tiny chance for an end portal to spawn already lit, so it’s POSSIBLE to go to the End in peaceful mode, but exceptionally difficult because most worlds won’t even have one of those portals)
i also hate monsters. i’ve only survived this long in hardcore by strip mining and lighting everything up and religiously sleeping if i’m working on a project. i wish i could switch this world to survival bc im really attached to it and make an updated backup world every session in case i die. i guess it’s not really hardcore then but i couldn’t bear to part with it
