Acheron Guardian

Six nights a week, three cursed obelisks rise in Acheron and Debenter. Defeat the guardians and destroy the obelisks.

Acheron Guardian arrived on October 8, 2026, from MU Season 12.

When#

At 11 pm (Brasília time) on Sunday, Monday, Tuesday, Thursday, Friday and Saturday. It lasts 30 minutes.

Where#

Three cursed obelisks, each of a random element:

• Alkmaar, in Acheron (89, 41).
• Ubaid, in Acheron (188, 101).
• Debenter (162, 54).

How it works#

1. Five guardians appear around each obelisk: the cursed elementals of Acheron (Undine, Salamander, Sylphid, Gnome and Hellraiser).
2. Once they are dead, 1 minute later the five from Debenter arrive (Sellihoden, Ukanva, Silla, Normus and Muff).
3. While any guardian is alive, the obelisk takes no damage. Once the second wave is dead, it becomes vulnerable.
4. Destroy the obelisk. Destroying all three before the 30 minutes are up ends the event.

Rewards#

Each obelisk is a medium boss: whoever dealt the most damage gets the owner prize, and whoever helped with at least 10% of the damage gets the participation prize. The guardians give their own experience and drops.
