This is (hopefully) an exhaustive list of optimal spawns for all categories of Minecraft speedrunning, in the mc, mcce and mc_juice boards, with currently 51 categories supported.
The list is made for the setspawn mod (only available for 1.15.2, 1.16.1, 1.16.5 and 1.17.1 at the time of writing), and has the goal of making this mod's usage seamless.
It must be pasted in the config folder of your minecraft instance.
If spawns are not working or not optimal, or if you'd like another seed to be added, just create a new issue or DM me on Discord (Baryllium#3810).
