Event Overview:

Time Clear: 70 seconds

Bring MS/Flight and Null Gravity Barrier Monsters

There are a ton of Mines and Gravity Barriers in this dungeon. Monsters with both MS/Flight and NGB are needed to have a stable clear.

Mob Clearing Bumps and SS

You will need to clear as many mobs on your first turn of every boss stage to mitigate damage. Bring monsters with Homing Piercers or Rebound Lasers.

1st Stage! Clear Revivers ASAP

Progression Order
1. Defeat the revivers
2. Defeat the bomb mobs
3. Defeat the remaining mobs

The bomb mobs will deal about 60000 damage to your monsters within 9 turns. Clear the revivers first and then the bomb mobs. Revivers do revive each other.

Invade! Mob over Mini Boss!

Mini Boss HP: 2.0 million

Progression Order
1. Defeat the mobs
2. Defeat the mini boss

The mini boss will summon more mobs for 2 straight turns. Make sure you clear them once the mini boss summons it. Also the rebound laser (bottom left CD) will deal a lot of damage so make sure you don't clump up your monsters.

Progression Order
1. Defeat the bomb mobs
2. Defeat the gasmask mobs
3. Defeat Astaroth

Just like the first stage, the bomb mobs will deal a giant explosion after 9 turns. Astaroth doesn't do that much damage so she can be left for last. Make sure you clear as many mobs in one turn before the ATK Down.

2nd Stage! Mob Clear!

Astaroth's HP: 1.4 million

Progression Order
1. Defeat the snake mobs
2. Defeat Astaroth

Snake's poison deals about 4000 per turn. Make sure you clear them or else you have to depend on heart items showing while you wait out the ATK Down.

3rd Stage! Clear the Smydras!

Astaroth's HP: 2.1 million

Progression Order
1. Defeat the Red Smydras
2. Defeat Astaroth

The Red Smydra's lasers are fixed. The left ones will shoot directly right and the bottom ones will shoot upwards. Avoid the lasers while taking them down.

4th Boss Stage! Defeat the Mech Birds!

Astaroth's HP: 2.1 million

Progression Order
1. Defeat the mech birds
2. Defeat Astaroth

The mech birds will do a lot of damage. The two on the bottom side will only shoot horizontally so if none of your monsters are there, you can leave them.
