I found LegionCraft and it is a OneBlock server that is all about grinding and getting stronger.
It says there is no pay to win so you win by skill and time played.
The big thing here is the bosses. You fight them and try to get rare key drops. Those keys can open crates and the crates give powerful gear and big rewards.
It also has a custom OneBlock world where you expand as you grind. It supports crossplay and there is a Bedrock port too.
I found this SMP where the story starts after a whole world gets destroyed and you get thrown into a new universe. It feels like survival but the war still follows you so it stays tense.
It is borderline anarchy so almost anything goes but hacks are not allowed. The big twist is a 3 lives system and if you lose all three you are done.
When you first join you get power gems to start off. There is also a shop system you can use with the shop command.
The world has custom structures and massive dungeons to explore. You can run into custom bosses and stronger mobs too. There are custom items and progression so you can keep grinding.
Build height goes up to Y 2034 so you can build super high if you want. More big updates are supposed to come later.
This is a Bedrock survival server built around a Wither Storm event. The world is meant to feel dangerous and you are here to survive the chaos.
The server uses the Decayed Reality V2.11 mod. Wither Storm destruction is expected so your base might not stay safe forever.
There is a simple rule set. No griefing bases and you need to listen to the owner. The main goal is to have fun and survive.
