How to Guard and CounterattackThe Mortal Cycle Walkthrough
The Mortal Cycle Map
The starting point and the entry route into the castle are partially randomized. Regardless of the entry route, aim for the boss Area in the Yotsuyama Castle Tower.
Beware of Places Where Enemies Spawn from the Ground
In places where a purple haze erupts from the ground, Yotsuyama Heavy Sentry will appear. It's recommended to back away and defeat the pursuing Yotsuyama Heavy Sentry first.
Doomed Toll Near the Castle Gate
Yotsuyama General in the Castle
A Riffwraith Appears in Yotsuyama Castle
Enter the castle from the 1st floor and proceed near the stairs, and a Riffwraith will appear. You can proceed without defeating it, but it's very troublesome as it will continue to attack from a long distance.
The Riffwraith's Attack has Unlimited Range
The Riffwraith's attack seems to have no range limit, and it will continue to attack even if you move away after it appears. Be careful, as its attacks can reach even outside of Yotsuyama Castle.
It uses two main types of attacks: a green reinforcement call and attacks that make the ground glow.
Beware of Reinforcements When It Glows Green
When the screen glows green, your position seems to be revealed to nearby enemies. If enemies start gathering, it's safer to move to a narrow passage and defeat them one by one.
Retreat When an Effect Appears on the Ground
A red effect is a sign of a Curse attack, and light blue is a time-stop attack. When they appear, retreat outside of the effect.
If the effect is the same as an Oasis, a field that only heals enemies will appear.
How to Proceed in The Mortal Cycle
Flow of The Mortal Cycle
- Defeat the Heavy Sentry and General before the Riffwraith
- Destroy the 3 Amplifier
- Defeat the Riffwraith
- Defeat Berserk Gomamusha
Yotsuyama Generals are placed on the Map, and Riffwraiths also appear inside Yotsuyama Castle. Since they can gather nearby enemies, it's safer to proceed while defeating enemies in your path.
However, the Riffwraith cannot be defeated until you destroy the three "Amplifiers". There is a proper order to defeating them.
Defeat the Heavy Sentry and General Before the Riffwraith
First, defeat the two Yotsuyama Heavy Sentries and the Yotsuyama General. Defeating them first will make it easier to destroy the third Amplifier.
Destroy the Three Amplifiers
At the end of the blue lines extending from the Riffwraith's body are the Amplifiers. If you destroy all three, the Riffwraith's Exoskeleton will break and it will fall to the ground.
First One is on the 2nd Floor of Yotsuyama Castle
The first Amplifier is on the 2nd floor, one floor up the stairs. There are often no enemies on the 2nd floor, so it's recommended to destroy this one first.
Second One is Near Berserk Humanoid
The second one is near two Berserk Humanoids, one floor up. Their Attack is high, so try to defeat the Berserk Humanoids one by one.
If you use Milene's Skill, it's also possible to ignore the Berserk Humanoid, destroy only the Amplifier, and escape.
The Third One is Near the Boss Room in the Tower
The third one is inside the Castle Tower where the boss room is. If you are spotted by a Yotsuyama General, two Heavy Sentries will appear in the passage.
It's dangerous to be cornered by all three, so if you're spotted by the Yotsuyama General, retreat downstairs for a moment.
Defeat the Riffwraith
Once you destroy the three Amplifiers, the Riffwraith will be downed. Riff Type enemies remain downed after their Exoskeleton is destroyed, so there's no need to rush your attack.
Defeat Berserk Gomamusha
Once you've collected 15,000 or more SPLithium, proceed to the boss Area. Berserk Gomamusha is a tough enemy that you fight in three forms, so you'll want to bring as many healing items as possible.

What to Do If You're Stuck
Acquire All Masteries
Berserk Gomamusha is the strongest enemy of Season 4. If you can't win, earn Mastery Points and challenge it after acquiring all Masteries.
If Your Cores Are Underwhelming, Take the Left Route
If the Cores you've obtained by Stratum 4 are underwhelming, you can opt to change your route to Great Scorch in Stratum 5 instead of proceeding to Blazing Trance.
Redo your preparations until you get Dodge Count+, health recovery-related Cores, or powerful Cores with three effects.
Change Your Body
If you can't win, change the Body you are using. For Exploration in Strata 1-6, Milene, Inva, and Timothy are recommended due to their powerful Skills.
If you're struggling with the third form, you can also try using Attacker Bodies like Ten or Pearl, get Cores that increase Attack, and try to overpower it.
