Scheduled Team vs Team battles: register at the Battle Statue in Lorencia, get split into blue and red teams and fight 10 minutes in the arena. Most kills wins, both teams get Zen.

15 scheduled world bosses across four difficulty tiers, aimed at different reset brackets, each with its own hand-picked drop table.

Declare war on a rival guild for a scored match on a normal map, or settle it with a Battle Soccer game on the soccer field.

Trade the Rena you collect from monsters with the Golden Archer in Lorencia for Zen and item rewards.

Every class has its full master skill tree up to Master Level 200 — including the Fist Master tree and the raven strengtheners — validated against the client.

The Dark Raven and the Dark Horse level up to +50 with you — the raven fights on its own attack attributes, the horse strengthens its Dark Lord — and both keep working while you level offline.

Search for open parties and join them without an invite, within a character-level gap of 150.

The MU Reforge launcher compares your client against the hosted manifest and downloads only what changed, verified with SHA-256 so an interrupted update never breaks your client.

A live countdown to every event and invasion, split into Events and Invasions tabs, with anything currently running marked ACTIVE. Hotkey H.
