Upcoming Class Reworks for MU Online Season 21
- According to information provided by IGCN, MU Online Season 22 is already running in a fairly complete state.
- Some of the class changes introduced in Season 22 will be brought to MU Online Season 21 in an upcoming update, which is expected within the next few weeks. These changes will be similar to those in Season 22, although they will be somewhat limited compared to the full Season 22 implementation.
- Once MU Online Season 22 is fully completed and stable, LifeMU plans to proceed with the Season 22 update across all servers.
What’s New in Season 22 Part 1-1?
- The biggest change is the rework of three classes: Dark Knight, Rage Fighter, and Slayer. IGCN has made significant changes to their skill systems, including skill damage, Mana/AG consumption, skill range, elemental values, and the 4th Skill Tree.
- Dark Knight: A new Rage Attack Power system has been introduced. Several Death Stab Master Skills are replaced by Fire Blow enhancements.
- Rage Fighter: New Attack Power types have been introduced: Melee, Area, and Divine.
- Slayer: A new Darkness Attack Power system has been introduced.
- Dark Knight and Slayer skills no longer rely on the previous Skill Attack Power (%) bonus.
- Mastery and Legendary weapons receive increased Damage and Combat Power.
- The maximum Attack Speed limit has been reduced.
- Several general DMG formulas have been adjusted based on the new version.
In addition, Season 22 introduces a reworked monster movement system, making the actual positions of monsters more accurately match what players see on their screens. Monster chasing and pathfinding have also been improved.
The Hunting Record now displays Base EXP and Bonus EXP separately alongside Total EXP. Quests have been expanded up to Level 1800, and MU Helper now supports the new hunting area entrances in Aquila’s Temple.
Additional information may be added and updated until the maintenance is completed.
