I found a casual SMP called Jujutsu Origins and it is just normal survival Minecraft but with the ORCA Jujutsu Craft mod on.
It is made for people who want cursed techniques and progression without hardcore roleplay. You can build your base grind your abilities and explore like usual.
PvP is optional so you can fight if you want but it is not about nonstop wars. The server feels small and chill and mostly about hanging out and having fun.
