SlayMU Online is a brand new international MU Online private server built for players who want a fair, long-lasting and balanced classic experience. We run Season 21 Part 2.3, the newest content available, with EXP rate x2 and Drop rate 10%, and we are a strict NON RESET server, which means your character progression is permanent and every level you gain truly matters. Grand Opening: 2 September 2026 at 12:00 GMT-3 (America/Sao_Paulo).

Because SlayMU is Non Reset, the economy and the ranking are built on real effort instead of endless resets. Leveling is meaningful, items keep their value, and the top of the ladder belongs to the players who actually invest time and skill. The x2 experience rate keeps the classic MU feeling alive: you will fight for every level, hunt in the right maps, build your character carefully and choose your gear with intention. The 10% drop rate keeps hunting rewarding without flooding the server with items.

Features: full Season 21 Part 2.3 content, all classes and their newest evolutions, Master and Majestic progression, complete quest and event system, Castle Siege, Chaos Castle, Blood Castle, Devil Square, Illusion Temple, Duel and PvP arenas, guild wars and regular GM events with real rewards. Anti-cheat protection and active moderation keep the field level for everyone, and the server runs on stable, low-latency hosting with 24/7 uptime.

SlayMU is free to play with no pay-to-win shop breaking the balance. Our team is active daily, listens to community feedback and posts every update publicly.
