Kotama and Academy Citadel: The Decomposer Moveset

With how defensive and offensive The Decomposer is, studying its moveset will give you a much-required leverage for victory.

Normal Attacks

Attack Name	Effect	How to Counter
Crab Smash	The Decomposer jumps high and drops down, sending ground waves to each side.	As The Decomposer jumps, run away from the middle to the corners. Wait for it to come down, and jump over the ground waves to avoid all damage. Instead of jumping, you can also use the Traction Rings in the arena.
Spitting Fire	The Decomposer spits fire from its mouth, covering the middle area of the arena.	You can either parry the fire or use the Traction Rings to get away. The fire stays on the ground for a few seconds.

Claw Attacks

Attack Name	Effect	How to Counter
Cross Pinches	The Decomposer’s arms produce a spark before crossing both arms in the arena’s middle to catch Kotama.	The key to avoid Cross Pinches is to stay away from the middle area. Once you see the sparks on both arms, jump away if you’re far from the Traction Rings.
Arm Smash	The boss raises one of its arms and smashes it on the ground, executing a devastating attack. Its direction depends on your location; far left means The Decomposer will raise its left arm	Don’t risk your health by moving in the opposite direction. Simply, run into the corner and get ready to parry the incoming Arm Smash.
Claw Swipe	Readying its arm, The Decomposer executes a swipe attack with one of the claws. It depends on the direction of Kotama.	Your cue to parry the Claw Swipe is a silver sparkle on the claw’s top. Parrying is your only option as the attack covers a huge area and leaves no space for dodging.
Claw Drag	Similar to the Claw Swipe, the boss buries one of its claws into the ground and drags it across the arena to Kotama’s location.	Jumping isn’t an option. As the claw approaches, use the Traction Ring in either direction to successfully avoid it.

Second Phase

Fiery Combo

Once the boss’s health falls below 50 percent, a warning sign will appear as it executes a full-combo attack.

Keep Kotama in the air by double jumping and using the Traction Rings on both sides. While the boss executes its combo, be cautious of the fireballs dropping from the sky.

How to Beat The Decomposer in Kotama and Academy Citadel

Once you reach the deepest layers of the Biology Academy, you will find the Decomposer boss in the far right area. Enter the arena, and the boss will jump down from the platform behind.

The battle begins with the Decomposer covering its face to increase defense. Start hitting its claws to cover them in Chronoshell. Ensure the distance between you and the boss is moderate to stay safe from its attacks.

If the Decomposer jumps to hit the Crab Smash, go below a Traction Ring and use it as you see the boss coming down. Drop and start hitting its claws; the early chronoshell will provide you with an advantage.

Don’t forget to explode the Chronoshell on the claws after they’re highlighted in purple. The explosion deals devastating damage to an enemy and heals Kotama.

Keep hitting and parrying the boss. Be ready to use the Traction Rings in both directions to dodge the Fiery Combo after The Decomposer’s health goes below 50 percent.

Additionally, dodge the falling fireballs to avoid significant damage. In the second phase, the moveset remains the same, but all the attacks are enhanced with fire damage; a small area of the arena will be covered in fire with each attack.

The Decomposer Rewards

Beating The Decomposer doesn’t really reward Kotama with anything significant other than three Temporalis. Later, Linne arrives at the arena and gives Kotama the Linne Keepsake.

Lastly, keepsakes are story items, which will be used in the later parts of the story; there are a total of four keepsakes.
