Hysteria SMP is a 1.21 survival server optimized for newer versions, with support for clients up to 1.21.11 and Bedrock players too. Come and join in the mass hysteria, claim your own land, and share it with your friends instead of worrying about griefing everywhere.
There's plenty to keep you busy beyond basic survival: custom items like obsidian tools, custom hats and cosmetics, MCMMO, daily quests, login rewards, playtime rewards, loot crates and keys, grave heads, and an auction house for trading. You can also link up with in-game chat and take part in daily Ender Dragon events.
If you want a laid-back SMP with economy, claims, and a bunch of little extras to work toward, Hysteria is set up for that. Friendly staff, grief prevention, and crossplay support make it easy to jump in and play with friends, whether you're on Java or Bedrock.
