Event Overview:

Stack Fire Monsters

With all the wood-element attacks, stack fire-element to reduce damage taken.

Bring All the NDW

Often damage-walls will cover all four sides. Along with conveyors sending your monsters toward the walls, bring all NDW monsters to protect yourself.

Focus on Mobs

Siren's frequent attacks won't do as much damage as the mobs'; focus on them first, but watch out for her R-Laser (5) and Meteor (11).

1st Stage! Use the Conveyors!

Progression Order
1. Defeat the mech birds
2. Use the conveyors to defeat the other mobs

First you clear the highest damaging mobs which are the mech birds. Next you can use the conveyors to quickly dispatch the other mobs.

2nd Stage! Ride the Conveyors Towards Siren!

Progression Order
1. Defeat the top left mech birds by pinching
2. Defeat the remaining mobs
3. Use the conveyors to defeat Siren

Just like the first stage, clear the mech birds because they deal the most damage. You can ride the conveyors when they point towards Siren to deal great damage to her.

3rd Stage! Aim for the Right Side of Siren!

Progression Order
1. Defeat the mech birds
2. Defeat the remaining mobs
3. Defeat Siren by bouncing the right side of her

There is a tight space for you to bounce your monsters on the right side of Siren. After you clear the mobs, aim your monsters to that part of the map.

1st Boss Stage! Clear the Mobs First!

Siren's HP: 2.1 million

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

Just like any previous stage, clear the mech birds first. Make sure you don't stack your monsters for Siren's rebound laser. The laser bounces more than normal enemies' with the same amount of power. There is a chance of taking 30000 damage from it if you are not careful.

2nd Boss Stage! Be Careful of the Conveyors!

Siren's HP: 2.3 million

Progression Order
1. Attack Siren by bouncing between her and the mobs
2. Defeat Siren
3. Defeat the remaining mobs

As long as you don't get slowed down by the conveyors, you can defeat her with relative ease. Make sure you aim for the spaces between Siren and the mobs.

3rd Boss Stage! Be Careful of the Conveyor When You SS!

Siren's HP: 4.7 million

Progression Order
1. Use your SS to defeat mobs and to deal damage to Siren
2. Defeat Siren

There is a slow conveyor. She has high HP so make sure you save your strike shots for the last bar only. Make sure you don't step on it when you are using your strike shots or else you won't dish out the optimal damage.
