Chaos Ruins - Seven Knights Idle Adventure

In Chaos Ruins, you form two teams of 15 heroes and face off against a boss and his minions.

Your goal is to get the highest score by doing as much damage as possible with your two teams combined.
You earn one entry per day, and an additional entry is available by watching an ad.

How do you unlock the game mode ?

The game mode unlocks after clearing stage 801.

Rewards

This game mode should not be overlooked, as it also brings in a large number of rubies each week.

The higher your score, the more chests you earn to open.
Chests are a huge source of experience and gold, and they also allow you to obtain pet summoning cards.

Each rotation, you will be assigned to a group corresponding to your level and will receive rewards based on your ranking.
You also get rewards based on your Server ranking.

The game mode lasts 7 days.

Group rank rewards

This is the ranking that interests us the most because we can get rubies as rewards.

How does Chaos Ruins work?

In Chaos Ruins, you form two teams of 15 heroes and send them one after the other against the same boss and his minions.
The boss cannot die — the goal is simply to deal as much damage as possible across your two runs combined.
When your first team finishes, the boss fully resets to his initial state before your second team enters. Each run is completely independent.

One important mechanic to keep in mind: the more health the boss will lose, the stronger his stats become.

Buffs

The boss has buffs that boost your heroes damage if the boss suffers a specific dot.
The buffs change with each new rotation.
So it's important to check which dot the boss is vulnerable to at the start of each new rotation.
PS: It is now also essential to have the overload debuff, as a boss buff increases hero damage by 100%.

Example of boss buffs in a rotation

To avoid having to change teams every season, you can build each team with heroes that can apply all 3 debuffs : poison, bleed, and burn.

How to form an effective team.

Each of your formations must have all the basic buffs and at least the dot for which the boss will take more damage.

How to approach your two teams

Since the boss resets between runs, there is no reason to balance your teams equally. You are not trying to be consistent across both runs — you are trying to maximize total damage. Build each team independently around the best damage composition you can field, regardless of overlap between the two rosters.

Also have a hero with concentrated attack, to avoid spreading attacks across minions.
Take advantage of the new hero released Nadan, who has a huge damage buff on this boss.

The two best heroes for applying the debuff concentrated attack are Nadan and Undercover Ruri; they deal more damage than the others.
If you don’t have them, you can always replace them with these heroes, even if they aren’t fully upgraded: Mirage or Aquila.

What about defense?

Chaos Ruins is not a survival challenge. The only defensive requirement is being able to survive your own overload debuff, since each team needs to apply it to boost damage. A single healer per team is enough to handle that — no need to build tanky formations.
Everything else should be focused entirely on damage output.

Teams used

As you can see, my two teams have the three debuffs that can boost my teams' damage.
First of all, this is useful because it means I never have to change teams depending on the damage buff.

But I also play heroes like Juri, who boosts her damage with burn and bleed, or Radius in team 2, who needs burn and poison.
So I combine business with pleasure.

Nadan and Undercover Ruri are also chosen for the concentrated attack debuff.

Not forgetting a hero with overload in each team.

With this team, I've achieved a score of 54,000,000,000 with fame at level 39.

Tips

In my opinion, it is essential to have at least two entry tickets per day for this dungeon in order to progress well.
This dungeon provides you with most of your daily gold.

So if you are a free-to-play player, don't hesitate to watch an ad to get an extra entry.

The XP and gold you will obtain depends on your maximum stage cleared.
The maximum number of chests that can be collected in a run is 1000.

Beginner's tip: Wait until you are stuck in your stage progression before opening the chests.
