Special boss invasions
Five classic bosses return as an invasion, in multiple copies with guaranteed jewel drops.
Updated:
Five classic bosses return as their own invasion: several copies of the same boss, all on the map where that boss normally lives.
| Invasion | Boss | Count | Map |
|---|---|---|---|
| Gorgon Invasion | Gorgon | 10 | Dungeon |
| Ice Queen Invasion | Ice Queen | 10 | Devias |
| Balrog Invasion | Balrog | 10 | Lost Tower (floor 7) |
| Hydra Invasion | Hydra | 10 | Atlans |
| Zaikan Invasion | Zaikan | 3 | Tarkan |
When they happen
A special invasion starts every hour, at :45, rotating through the five in order: Gorgon, Ice Queen, Balrog, Hydra, Zaikan. Each specific one comes back roughly every 5 hours, about four times a day. Every invasion lasts 30 minutes. Killing invasion monsters also earns you Game Points (see the MU Item Shop).
What they drop
Each of these bosses drops guaranteed jewels on death:
| Boss | Guaranteed jewels |
|---|---|
| Ice Queen | 1 (Bless or Soul) |
| Gorgon | 2 (Bless or Soul) |
| Balrog | 3 (Bless or Soul) |
| Hydra | 5 (Bless, Soul, Life, or Chaos) |
| Zaikan | no jewels (drops a Heart of Dark Lord, which opens into either Loch’s Feather or Crest of Monarch, 50/50) |
These bosses are a little easier than other end-game challenges, meant to be worth hunting for their guaranteed jewels.
Tracking the invasion
Just like the Golden Invasion, a bar near the top of the screen shows how many of the boss are still alive on your map while the invasion is running.
