Deep nightmare - Seven Knights Idle Adventure

Deep Nightmare is a game mode where you must face bosses, one boss per level, with three different teams.
To pass the stage, you must defeat the boss with each of your teams.

How to unlock it

You unlock Deep Nightmare once you have completed level 30 of Nightmare mode.

Information

The Nightmare shard bonuses are also active in this game mode.
There is no access limit in this mode; you can restart a battle an infinite number of times.

Tips

You must defeat the boss with each of your teams, so you need to build 3 balanced teams.

Note that the further you progress, the more the boss will have dodge and critical resistance.

Each of your teams must have the core buffs and debuffs:

In addition, it is important to have one hero per team who boosts damage against bosses in Nightmare mode:

• Velika (+50% damage nightmare Boss)
• Medea (+50% damage nightmare Boss)
• Alcyion (+50% damage nightmare Boss)
• High Lord Sun Wukong (+70% damage nightmare Boss)

Some bosses have a healing buff, so it's also important to choose a hero who can remove buffs from bosses.
Equip each team with one or more heroes with attacks that hit multiple times, as some bosses have a veil buff (20 attacks canceled).

Raise your Nightmare Shard level (or rather, wait for it to rise).

Solve the critical hit resistance problem.

At first, critical hit resistance will not pose any problems, but it will quickly prove to be a real challenge.

This type of game mode is why it's useful to have heroes with critical hit potential rolls.

Since the release of the Awakening heroes, add a hero with a 36% critical hit rate buff, such as Awakening Rachel.

Wait for level X of Nightmare mode to get a critical hit rate increase to X% for all of your heroes.

The hardest part is often applying the first decrease critical hit rate resistance debuff.
This is because at the start of the battle, your heroes are not buffed and may miss their critical hits and therefore fail to apply their buffs.
(Of course, this is in cases where the hero's buffs are applied via critical hits.)

Use aura

The solution is to use a hero with an aura that increases the crit rate.
This will increase the crit hit rate for all heroes without having to touch the boss, so more chances to apply decrease critical hit resistance.
Vicky is the only hero with this ability.

Use active skill

An another solution is to use a hero with a decrease crit rate resistance debuff on their active skill.
Even if it is 20% (instead of 24%), this will allow you to rely solely on your accuracy to apply the debuff.
In the case of a reduction to only 20%, it is still important to have a second hero at 24%.

Michaela and Taka have this ability.
