I found a server called Peaceful Craft and it is made to be chill and easy to join. You do not need any mods to get in so it feels simple.
The server has keep inventory on so dying is not a big deal. PvP is turned off so players are not fighting all the time.
It also has a claim system so you can protect your builds. The server opens at 7:00 pm on Thursday the 19th est time and it says it has lots of unique features.
Peaceful Craft No Mods Needed
GG.MINEWIND.NET New Server IPCobbleSMP Fresh Cobblemon Survival Server
CobbleSMP is a brand new SMP that uses the Cobblemon mod. It makes survival feel like Minecraft with Pokemon running around so you can play and explore.
It is Java only and you need the Cobblemon mod to join. The server is hosted on Aternos so it is not online 24 7.
There is no claiming so you have to respect other players builds. Do not grief because if you grief you get banned.GG.MINEWIND.NET New Server IP
