You can pick one:
21 Day Horde - Base mod, plus your blood Moon horde comes every 21 days, instead of 7.
7 Day Horde Streamer Edition = No bad language, no strippers, regular blood moon
21 Day Horde Streamer Edition = No bad language, no strippers, blood moon every 21 days
Ignore the others, unless you want the on the official DONA server, in which you'd want to use Dawn of the new Apocalypse.
