What Season 22 brings
Webzen has not published the Season 22 patch notes yet. Their public roadmap currently ends at Season 21-1 Update 3, the Sanctuary of Aquilas elite zone, so anything you read elsewhere about Season 22 classes, maps or item tiers is guesswork for now. We will list the confirmed changes here, and in the news, the moment the official notes are out.
What Season 22 builds on is well documented. If you are coming back to MU Online after a break, the last few seasons changed the endgame a lot:
- Season 21 — the Crusader class, Imperial as the 2nd Legendary item tier, Rakion of Oblivion, level cap 1,800 and required stats no longer rising with upgrade level.
- Season 20 — the Alchemist class and the Temple Guard Legendary tier.
- Season 19 — the 5th class change and the Ability system.
- Season 18 — the Illusion Knight and Artifacts.
Every earlier version is covered in the MU Online season guides, from Season 1 in 2005 onwards.
