Currently, there is no special Deltarune discord server, so the discord button links to the Undertale Speedrunning Discord, where part of the server is set aside for Deltarune runs.

Also, the leaderboard can possibly be subject to big changes in the next couple of weeks based on the runs and then eventually when the full game releases most things will be completely different.

hey this may not have anything to do with /\ but i need help and i don`t want to post on the front. how do i set up my obs to capture Deltarune because it is just not showing up

So, when these leaderboards change, will the chapters of Deltarune be IL (Individual Level) runs? Just curious.
