How to Clear Nightmare 11-30

This guide covers how to clear Nightmare 11-30 in Seven Knights Re:Birth. Including recommended heroes, enemy info, what equipment to use, what type of immunity, and more.

Overview of Nightmare 11-30

Difficult Without Proper Team Comp

Nightmare 11-30 is difficult to brute force, especially without a balanced team or sufficient gear. Relying solely on high offensive units will not guarantee victory. This stage heavily emphasizes and rewards proper team building, making the right tools and immunities essential for clearing it.

Requires 2 Teams

It’s important to note that Nightmare Mode requires players to set up two separate teams per stage. This means you’ll need to raise more heroes and carefully balance both teams to ensure consistent clears.

Enemy Info

Round 1 and 2
Rook	Rudy	Chancellor	Pepe	Aragon

In Nightmare 11-30, the main threat is Rook who can easily one shot any hero with Skill 1. The rest of the enemy lineup is also quite formidable Rudy, Rook, and Pepe providing the entire team with ample ways to sustain the team through heavy damage.

To clear this stage, it is highly recommended to have sufficient Crowd Control and Debuff Removal to prevent Rudy’s Link and Rook's Barrier from stacking.

Nightmare 11-30 Recommended Heroes

Immunities

Recommended Hero	Details
Evan	Evan grants all allies Stun Immunity and provides a Barrier and Defense Boost to the entire team. It's advisable to have his skills enhanced. Alternatively, if you have two healers, you can swap him out for an additional DPS. Recommended Set: Guardian/Gatekeeper
Sieg	Seig is also a good choice for a Tank and can increase Physical Damage and provides minor party healing and Stun Immunity for defensive and Sustain Utility. Recommended Set: Guardian/Gatekeeper

Crowd Control

Recommended Hero	Details
Yu Shin	Yu Shin is an excellent Crowd Control hero who provides a team-wide Effect Hit Rate boost. He also gains two turns of All Damage Immunity, greatly improving his survivability. His skills can inflict Paralysis on either all enemies or up to three targets. Recommended Set: Gatekeeper/Spellweaver
Mercure	Mercure is a powerful hero with great utility. He can Stun all enemies, inflict Incoming Healing Reduction, and apply Magic Flux when three Magic heroes are in the team. Magic Flux deals 12% of the target’s max HP (up to 90% of the caster’s Attack) and stacks up to seven times. His passive reduces enemy Effect Resistance and limits incoming damage to 40% of his max HP, improving survivability. Recommended Set: Gatekeeper/Spellweaver
Eileene	Eileene is a more offense-oriented Crowd Control hero who provides a team-wide Physical Attack boost, making her a strong pick for physical teams. Recommended Set: Gatekeeper/Spellweaver
Kagura	Kagura is a strong alternative to Eileene for Physical Teams, offering both Critical Damage and Physical Damage boosts from her passive. She can also inflict Petrify preventing the enemy from applying All Damage Immunities. Recommended Set: Gatekeeper/Spellweaver

HP Alteration

Recommended Hero	Details
Freyja	She is a top-tier magic AoE attacker capable of HP Alteration on all enemies, Ignore Defense, Bleed, and Defense Reduction based on the number of buffs removed. Since her Effect Hit Rate UP activates when organized with Magic heroes, she has excellent synergy with Mercure and Juri. Recommended Set: Assassin/Avenger
Platin	While Platin may not provide much in PvE content, he is still a decent choice as a tank when you need extra damage with HP Alteration alongside Buff Removal. Recommended Set: Guardian
Li	Li's Taunt skill grants two hits of Physical Damage Immunity. Additionally, his passive lets him counterattack while healing based on his Max HP, and his HP Alteration skill can set an enemy’s HP to 28%, making him invaluable for tough encounters. Recommended Set: Gatekeeper

Death

Recommended Hero	Details
Kris	Kris is the core of any Death Team, allowing you to clear stages without relying on high damage output. Recommended Set: Gatekeeper/Spellweaver
Knox	Similar to Kris, Knox is used to inflict Death on enemies. His passive increases the Death infliction rate, making him an excellent support hero for Kris in Death Teams. Recommended Set: Gatekeeper/Spellweaver
Aquila	Aquila is the newest addition to the Death Team. She can inflict Death with her Skill 2 and reduce the Death Turn count by 2 with Skill 1, greatly speeding up Death Team clears. She also provides the Link buff for the entire team, significantly boosting overall survivability. Recommended Set: Gatekeeper/Spellweaver

Continuous Healing & Barrier

Recommended Hero	Details
Evan	Evan grants all allies Stun Immunity and provides a Barrier and Defense Boost to the entire team. It's advisable to have his skills enhanced. Alternatively, if you have two healers, you can swap him out for an additional DPS. Recommended Set: Guardian
Yui	Yui is the top recommended support for Adventure stages. She provides continuous healing, greatly boosting team survivability. Enhancing her healing skill for an extra turn is highly recommended. Recommended Set: Paladin/Gatekeeper
Lina	Lina provides a Damage Boost and Continuous Healing. Paired with Yui, they ensure consistent team healing throughout the battle. Lina doesn't require any Skill Enhancement. Recommended Set: Paladin/Gatekeeper

Damage Dealer (DPS)

Recommended Hero	Details
Teo	Most recommended DPS for this Adventure level. His skills deal high damage to all enemies, and with Immortality and All Damage Nullification, his survivability is high. Two Skill Enhancements are recommended but optional. Recommended Set: Assassin or Avenger (T6)
Kyle	Another top contender for best Physical DPS, Kyle’s skills feature exceptional damage scaling, and his passive deals a percentage of the enemy’s Max HP every two attacks. He performs best when paired with two other Attack Type heroes and gains an additional 27% Crit Rate from his passive, making him very easy to build. Recommended Set: Assassin
Yeonhee	Yeonhee is a Magic Damage hero with a Defense-Ignoring Triple-Target Attack. She is an excellent DPS, capable of inflicting Sleep, and provides Magic Attack Boost to all allies while granting All Damage Nullification to herself. Recommended Set: Assassin
Klahan	Klahan has skills that target all enemies with decent damage. When an enemy's HP drops below 50%, he deals additional piercing damage. He also inflicts Damage Reduction on enemies and grants himself a Physical Attack Boost. Recommended Set: Assassin
Freyja	She is a top-tier magic AoE attacker capable of HP Alteration on all enemies, Ignore Defense, Bleed, and Defense Reduction based on the number of buffs removed. Since her Effect Hit Rate UP activates when organized with Magic heroes, she has excellent synergy with Mercure and Juri. Recommended Set: Assassin/Avenger

Sub-DPS & Utility

Recommended Hero	Details
Melia	Melia is an exceptional premium pick for Magic Teams, as she can provide a barrier for the entire team with a full lineup of Magic heroes. She also has great survivability and deals respectable fixed damage while increasing enemies’ cooldowns. Recommended Set: Guardian/Gatekeeper
Elysia	Elysia is an AoE hero with exceptional support capabilities, including Defense Reduction, Silence, Buff Duration Reduction, Debuff Removal, and Increased Missed Chance. She can be used to counter Status Ailments and Crits. Recommended Set: Gatekeeper
Biscuit	Biscuit provides excellent utility with her Defense Debuff, Buff Removal, and Weakness Hit Chance Boost, making her a strong addition to almost any team. Recommended Set: Vanguard/Gatekeeper
Ace	Ace's skills are highly valuable in Nightmare 11-30. He inflicts Defense Reduction, Physical Vulnerability, Buff Duration Reduction, and Reduced Incoming Healing, creating opportunities for your team to deal higher damage and complete the run faster. Recommended Set: Vanguard/Gatekeeper
Rachel	She grants all allies a Weakness Hit Chance Boost and inflicts Defense Reduction and Physical Vulnerability on 3 targets. While one of her skills targets only a single enemy, her self-revive greatly enhances her survivability. Recommended Set: Vanguard/Gatekeeper

Nightmare 11-30 Team Formation Example

Depends on Your Roster

As Nightmare requires two teams to clear, the best heroes to bring for each team will vary. However, the Freyja Burst and Death teams stand out among the rest.

With Freyja teams excel in damage and Crowd Control while Death teams focus on survivability and clearing enemies through the Death debuff.

Freyja Burst Teams
(Recommended for Round 1)

Front	Front	Front	Front	Back
Vanessa Crowd Control Magic Vulnerability (T6) Flex Slot	Mercure Magic Flux Crowd Control Flex Slot	Kyrielle Damage Buffer	Freyja HP Alteration Damage Dealer	Yeonhee Damage Dealer

This is a strong team for 11-30 Wave 1. Mercure or Vanessa provides initial Crowd Control to stun enemies, followed by Freyja’s HP Alteration to set up a quick wipe. The team is fairly flexible, as any hero with a full-team AoE Crowd Control skill can replace Mercure or Vanessa.

Magic Team

Front	Front	Front	Front	Back
Lina Elysia Healer Buff Duration Reduction Debuff Removal Flex Slot	Mercure Magic Flux Flex Slot	Vanessa Biscuit Chloe Debuffer/Immunity (Flex Slot)	Yu Shin Rin Freyja HP Alteration Flex Slot	Yeonhee Freyja Damage Dealer

For Magic teams, Mercure is highly recommended for his Magic Flux effect, which can easily carry your team through early Nightmare stages. Note that Mercure requires three Magic-type allies to activate Magic Flux..

Physical Team

Front	Front	Front	Front	Back
Evan Sieg Tank Physical Buffer (Sieg) Stun Immunity	Yui Lina Healer	Eileene Kagura Crowd Control/Buffer	Biscuit Ace Debuffer (Flex Slot)	Teo Kyle Damage Dealer

For Physical-centric teams, Kyle, Teo,or Klahan are recommended as primary damage dealers due to their high damage output. Kagura and Eileene complement them well by providing strong damage buffs and applying Crowd Control effects to enemies.

Death Team
(Recommended for Round 2)

Front	Front	Front	Front	Back
Rudy Platin Tank	Yui Alice Lina Healer	Evan Sieg Stun Immunity	Knox Aquila Inflict Death Death Support	Kris Inflict Death

When using a Death Team, prioritize survivability over damage. The Death debuff will automatically defeat enemies after 3 turns or once they reach 2 stacks, making endurance the key to victory.

While Knox and Aquila can be used together, it’s generally better to choose one. Knox boosts Death Effect success rates for consistency, while Aquila enhances survivability with Link and shortens Death Turn count for faster clears.

Tips!	It is recommended to forgo Buff Removal in 11-30 Nightmare when using a Death Team, as neither Link nor Barriers affect the Death status effect.

Strategy & Tips

Bait Healing Skills

In Nightmare 11-30, using HP Alteration as an opening skill will trigger Pepe to heal the team. If you lack sufficient follow up damage, it is best to bait Pepe’s healing or crowd control the enemy team before using Freyja’s HP Alteration.

Tips!	Alternatively, if you have enough follow up damage after Pepe’s healing, you can bait the heal with HP Alteration and quickly burst the remaining health.

Buff Removal or Duration Reduction

For Wave 2 of 11-30, having Buff Duration Reduction or Buff Removal is crucial to prevent the enemy team from stalling with Link and Barrier Effects Effect.

Crowd Control is Effective

Enemies in both Wave 1 and Wave 2 of 11-30 have 35% Effect Resistance, making it essential for your Crowd Control and Death heroes to have sufficient Effect Hit Rate to land their debuffs.

HP Alteration

Inflicting HP Alteration is an effective way to deal damage, as it sets enemies' HP to a fixed threshold, ignoring both their HP and defense. Platin stands out as a strong option for this role, serving as both a tank and a source of HP Alteration. This effect also ignores All Damage Immunity, allowing you to use this effect while the buff is active.

Freyja Excels in 11-30

Freyja’s HP Alteration skill targets all enemies on the field, making it highly effective in either wave and allowing you to quickly burst them down.

Death Teams

If you have Kris, running a Death Team is a strong alternative. This setup lets you bypass enemy mechanics and stats entirely by instantly defeating them after 3 turns or once 2 stacks of Death are applied.

Enhance Hero Skills

Enhance your heroes' skills, prioritizing tanks and healers to boost their effectiveness and utility. Skill Enhancement materials can be obtained from Story Event rewards, the Shop, and the Infinite Tower.

Use Protective Formation

Protective Formation is the recommended setup for Nightmare 11-30. At Level 20, it boosts Back Row heroes' Attack by 26% and grants Front Row supports and healers a 6.5% Defense increase. Other formations can also work but require more investments into your characters and gear.

Tips!	Make sure to enhance the formation level for increased back row and front row effect. The higher the Formation level, the better.

Ultimate Enhance Your Team

If you have an Ultimate Enhancement Material, Leah, or spare Fusion fodder, it’s worth investing in adding a weapon slot to your strongest 6★ Legendary DPS or an armor slot to other team members. Nightmare 11-30 is extremely difficult without Ultimate Enhancements, so make sure your core heroes are at least fully enhanced to maximize their survivability and damage output.

Ruby Farm for Fusion Fodder

Once 14-1 or Nightmare 1-1 becomes available, players should begin Ruby Farming to gather enough fodder for fully Ultimate Enhancing their team. This greatly improves survivability and makes clearing stages much easier.

Use Skill Queue

Auto Skills offer convenience, but they don't always select the optimal skills in critical situations. It's best to use the Skill Queue to start with a buff, then monitor combat and manually activate skills as needed.

Tips!	Strategically, queue buffs first, such as 'Shield', then use priority skills manually to gain the upper hand.

Unlock Hero Potential

To clear high-difficulty Power Up Dungeons, increasing Hero Potential is essential. If you are struggling to clear, try increasing the Hero Potential of your party members.
