I want to try to speedrun reach height limit set seed pre 1.18 like kobra and Khalooody did, but i can't figure out which version i should use to get the set loot in the ruined portal chest. Can anyone help me with that?

Well it says they both ran in a 1.16 version, I’m not sure which exactly, my best advice is to just try different versions until you find it. Maybe look at some different 1.17 versions. Sorry I’m not much help
