MU Online Season 21 Part 2-3: CryWolf & Classes Renewal
The newest MU Online update has landed, and it is a big one. Season 21 Part 2-3 (CryWolf & Classes Renewal) brings a fresh endgame map, two Elite Zones packed with beefed-up monsters, a new guardian, top-tier Crusader gear, a higher level cap and full reworks for three classes. Here is everything inside the patch, in plain words.
What Is Raklion of Oblivion?
Raklion of Oblivion — some patch notes call it Forgotten Raklion — is a new hunting map built on top of the classic Raklion you may remember. Think of it as Raklion’s evil twin: darker, tuned for high-level characters, filled with brand-new monsters and guarded by a new boss. If your character has outgrown the usual endgame spots, this is where your grind moves next.
On top of the new map, the update adds two Elite Zones: the Forgotten Raklion Elite Zone and the Aquilas Temple Elite Zone. Elite Zones are special areas where the monsters are much stronger than normal — but the rewards scale up to match. They are aimed straight at endgame grinders who want harder fights and better drops in the same session. Check the events page to see what else is running while you farm.
The 8th Guardian: Rhino
Guardians are the mount-style companions that ride into battle with you, and MU Online Season 21 Part 2-3 adds the eighth one: the Rhino. There is also a Rhino (Rare) version for players chasing the upgraded tier. A new guardian means a new power step for every build, so expect Rhino hunting to be a big deal in the first weeks of the patch.
New Gear: Crusader Legendaries and 9th Mastery Earrings
🛡️ Crusader 2nd Legendary Equipment
The Crusader — the newest of the 16 classes — gets its second wave of legendary items: new Sets, Hammers and Shields made only for this class. If you main Crusader, this is your next gear goal after your current setup is done.
💠 9th Mastery Earrings
A whole new earring tier arrives, headlined by the new Earring of Compassion. Earrings are late-game accessory slots, so a fresh tier means every endgame character has something new to hunt, not just Crusaders.
Level Cap Raised to 1800
The maximum level climbs to 1800, and the Season reward track was updated so the road up actually pays out along the way. In short: even if you were parked at max level before this patch, you now have a real reason to log in and grind again. New players can start that climb today — create an account and grab the client from the download page.
Which Classes Changed in Season 21 Part 2-3?
Three classes got a full “Character Renewal”, which means their skills and damage math were rebuilt, not just number-tweaked:
- Elf: rebuilt around the new Combat Power stat — her kit now scales through it.
- Magic Gladiator: two-handed weapon builds got a real buff, so big-sword MG is back on the menu.
- Illusion Knight: also reworked around Combat Power, changing how the class deals damage.
- Smaller touches: Lemuria Mage’s shield mastery and Gun Crusher’s wizardry damage formula were adjusted too.
Combat Power is the headline system here: a new power stat paired with class-based attack types called Gale, Chaos and Illusion. Under the hood, the skill math for these classes now lives in FormulaData.xml instead of Lua scripts — a detail server admins care about more than players do, but the upside for you is skill damage that behaves the same way every single time. Our guides section will break down the new builds as the meta settles.
CryWolf Renewal and the System Changes
The update is literally named after it: the classic CryWolf fortress-defense event has been reworked, so the old wolf-side-versus-invaders fight is worth queueing for again. Alongside it come some quality-of-life changes that affect everyone:
- Simpler item requirements: the Strength/Agility needed to wear an item no longer rises as you upgrade it — a +15 piece asks for the same stats as its +0 version.
- Socket rates adjusted: socket item enhancement chances in the Chaos Combination system were rebalanced.
- Boss Battle Together: the monsters in this group boss event were retuned with fresh attributes.
- Plus: the usual batch of smaller fixes, performance work and general polish.
