Sky Empires is an RPG SkyBlock server where you build your own empire in the sky and work your way up through classes, combat, and progression. Pick from 5 classes, Warrior, Mage, Archer, Rogue, or Tank, and use them to fit your playstyle as you explore, fight, and grow your island.
There's plenty to do besides the usual SkyBlock grind too. You'll find clan systems, Island Wars, a dungeon with 4 powerful bosses, a PvP arena with rewards, plus a market, bank, and casino for the economy side of things. Custom weapons, armor sets, professions, and seasons with rewards help keep it moving, and Bedrock support is included as well.
If you like SkyBlock with more RPG flavor, this one leans into both PvE and PvP without losing the economy and island-building part. Cracked is allowed, and the server is running on 1.21.4.
