Dragon’s Lair B10/B12, commonly called DB10/DB12, is the pinnacle of the Dragon’s Lair dungeons in Summoners War. It is one of the next objectives to complete after Giant’s Keep (GB12) and Trial of Ascension Normal (ToAN).

Nestled within the Cairos Dungeons, DB12 is renowned for offering you a chance to obtain some of the game’s most sought-after rune sets, particularly coveting Violent runes. These runes are pivotal in boosting a monster’s potential, granting them a 22% chance to take an additional turn, which can be a game-changer in both PvE and PvP scenarios.

DB12 is characterized by its formidable fire-element Dragon boss, accompanied by two crystal towers that give the Dragon immunity and continuously damage your team, respectively. The boss possesses daunting abilities, including a skill that strips and debuffs your monsters, demanding strategic planning and robust team composition for success.

Success in DB12 is contingent on several factors. A balance between damage output, control, and survivability is vital. Since the Dragon can cleanse itself of debuffs, monsters that can strip or block buffs, like Belladeon or Chilling, become essential in the higher-level dungeon. Furthermore, given the increased difficulty from its predecessor, DB10, you need monsters with high-quality runes, sufficient speed, and resilience to endure the Dragon’s powerful onslaughts.

Key Takeaways for DB10 and DB12

  • Team Composition: Building a stable team is vital. A typical DB12 team will have a combination of cleansers, healers, damage dealers, and units that can control or strip buffs. 
  • Verdehile (Fire Vampire) is almost universally recommended as the leader for his turn-cycling capability.
  • Strategies and Tactics: Focus on survivability first. Dragon’s Lair enemies hit hard, so you’ll need adequate HP and defense stats. 
  • Crowd control (CC) and buff stripping are essential. The Dragon boss gains immunity and can bolster its strength, making the battle tougher. 
  • DoT (Damage over Time) units, such as the Water Homunculus or Spectra, are highly valuable. The boss has a large HP pool, and DoTs effectively chip away at it.
  • Target Priority: There’s an ongoing debate over targeting the boss directly versus taking out the towers first. The safest approach for newer teams is often to eliminate the right tower (which applies immunity) before focusing on the boss.
  • Rune Quality and Set Prioritization: Violent runes are king in DB12 for many units, allowing them more turns and greater flexibility. Accuracy is critical for units that need to strip buffs or apply debuffs. Aim for at least 65% accuracy for consistent results.
  • Common Pitfalls: Not investing in skilling up key monsters can result in reduced success rates. Underestimating the importance of speed tuning. Ensure that your cleanser goes before your damage dealers, for instance.

Advanced Tips: Some players use speed teams that aim to clear the dungeon in under a minute. This often involves serious damage, AoE nukers, and superb rune quality. Some dot teams rely heavily on stacking damage-over-time debuffs to burn through the boss’s HP.

Why Should You Farm Dragon’s Lair?

summoners-war-dragons-lair-unit-selection

Dragon’s Lair, specifically the DB12 floor, is a pivotal dungeon in Summoners War that every serious player should aim to conquer and farm consistently. Here are the primary reasons why:

  1. High-Quality Rune Drops:
    • Dragon’s Lair is the exclusive source of the Violent rune set, one of the game’s most versatile and widely used rune sets. Violent runes allow monsters to take additional turns, offering a dynamic advantage in both PvP and PvE scenarios.
    • The dungeon also drops Guard, Focus, Endure, Shield, Revenge, and Will rune sets, all of which have unique applications across various teams and content.
  2. Skill-Up Material:
    • The dungeon occasionally drops summoning pieces for 4-star monsters, which can be used either to acquire new units or provide skill-ups for existing ones.
  3. Late-Game Preparation:
    • Farming Dragon’s Lair prepares players for late-game content. The experience and the rune quality will be beneficial when branching out to other challenging content like Necropolis B12 (NB12) or the higher levels of the Trial of Ascension Hard (ToAH).

Ideal Team Composition for DB10 Starter Team

A reliable starter team provides a foundation for farming the dungeon, securing essential runes, and paving the way to DB12. Here’s an ideal team composition for a DB10 starter team:

Below, we have included a table of all the runes you require for your starter team.

Verdehile (Fire Vampire)

summoners-war-verdehile
  • Role: Leader, Turn Booster
  • Rune Recommendations:
    • Primary: Swift/Blade or Violent/Blade
    • Stats Focus: Speed, Critical Rate (aim for 100%), HP
    • Slot 2/4/6: SPD / CR or HP% / HP%

Verdehile’s leader skill increases the speed of all allies in the Cairos Dungeon by 28%, which helps your team cycle turns faster. His first skill grants him another turn 20% of the time when he lands a critical hit, and his passive ensures that the attack bar of all allies is increased by 20% if he lands a critical hit. This makes him an excellent turn cycler.

Belladeon (Light Inugami)

summoners-war-belladeon
  • Role: Healer, Defense Breaker, Buff Stripper
  • Rune Recommendations:
    • Primary: Swift/Energy or Violent/Energy
    • Stats Focus: Speed, HP, Accuracy (for reliable debuff application)
    • Slot 2/4/6: SPD / HP% / HP% or ACC

Bella provides a defense break on skill 1, a group heal with an attack bar boost on skill 2, and a buff strip on skill 3. This makes Bella an invaluable support unit, ensuring your team stays alive while also stripping the immunity buff from the dragon.

Sigmarus (Water Phoenix) or Veromos (Dark Ifrit)

summoners-war-sigmarus
  • Role: Damage Dealer (Sigmarus) / Cleanser (Veromos)
  • Rune Recommendations:
    • Primary: Fatal/Blade or Violent/Blade
    • Stats Focus: Attack, Critical Rate, Critical Damage, HP
    • Slot 2/4/6: ATK% or SPD / CR or CD% / ATK% or HP%

Sigmarus offers AoE damage and HP%-based attacks, making the runs faster. Veromos, on the other hand, can cleanse harmful effects from your team, which helps you survive against the continuous damage crystals and the dragon’s debuffs.

Spectra (Fire Griffon)

summoners-war-spectra
  • Role: Speed Debuffer, Special Assault Damage
  • Rune Recommendations:
    • Primary: Swift/Energy or Swift/Focus
    • Stats Focus: Speed, HP, Accuracy (for reliable debuff application)
    • Slot 2/4/6: SPD / CR or HP% / HP% or ACC

Spectra’s skill 2, “Special Assault,” deals damage based on the enemy’s max HP, making it effective against the high HP dragon. Moreover, his AoE slow and attack bar reduction can be a game-changer, slowing down the towers and the dragon.

Megan (Water Mystic Witch)

summoners-war-megan
  • Role: Attack and Defense Buffer, Buff Stripper
  • Rune Recommendations:
    • Primary: Swift/Energy or Swift/Focus
    • Stats Focus: Speed, HP, Accuracy (for buff stripping and applying debuffs)
    • Slot 2/4/6: SPD / HP% / HP% or ACC

Megan provides an attack and defense buff, which is crucial for both survivability and increasing your team’s damage output. Her skill 2 can also strip the immunity buff from the dragon.

Dragon’s Abilities and Countering Them

In Summoners War, the Dragon in Dragon’s Lair DB10 & DB12 has several unique abilities that can challenge unprepared players. Let’s explore these abilities and their counter-strategies.

Dragon’s Abilities:

  1. Dragon’s Breath: Inflicts damage on an enemy and puts the enemy to sleep for 1 turn with a 15% chance.
  2. Dragon’s Roar: Removes all beneficial effects on all enemies, inflicting damage and weakening their Defense for 3 turns.
  3. Immunity Passive (Right Crystal): Grants immunity to the Dragon, preventing any debuffs.
  4. Continuous Damage (Left Crystal): The left tower applies a continuous damage debuff for 3 turns.

Countering the Dragon’s Abilities:

  1. Dragon’s Breath:
    • Counter: Having units that can cleanse or provide immunity can be helpful. Units like Veromos can cleanse sleep, ensuring the team can function without disruptions.
  2. Dragon’s Roar:
    • Counter: Maintaining a solid defense by strengthening your monsters’ defense stats or using monsters that can provide a defense buff is essential. Belladeon, with its heal and defense buff, is a great option. Ensure your monsters have high resistance to mitigate the chance of getting a defense break.
  3. Immunity Passive (Right Crystal):
    • Counter: A buff stripper is crucial. Belladeon, with its Seize skill, can remove the Dragon’s immunity, allowing your team to apply debuffs. Another approach is to defeat the right crystal first, removing the source of immunity. However, this strategy can be riskier as it extends the battle duration.
  4. Continuous Damage (Left Crystal):
    • Counter: A cleanser like Veromos is pivotal for DB10 runs as it frequently removes continuous damage effects. An immunity provider like Delphoi or Woosa can also prevent these harmful effects from being applied in the first place. Alternatively, a direct focus on the Dragon, with a team built to nuke or deal substantial damage, can end the battle quickly before continuous damage becomes a significant threat.

In conclusion, building a team that can cleanse, provide immunity, strip buffs, and deal substantial damage is vital for success in DB10. It’s always essential to be adaptive and ensure your team’s synergy aligns with countering the Dragon’s abilities effectively.

Having the right runes with the proper stats is more critical than having high-grade runes. For instance, a 5-star rune with perfect stats can be more beneficial than a 6-star rune with subpar stats.

Advanced Units for DB10 And DB12

Once you’ve built a reliable team and consistently clear DB10, you can look into advanced strategies to speed up your runs and increase efficiency. Also, these units will help you clear DB12 once you have acquired better runes from DB10 and other game sources. You must replace your starter units!

While your starter team serves you well in their early DB10 conquests, faster options are available as you progress.

The quickest and most successful DB12 teams will require that the boss takes minimal turns throughout the dungeon run.

Here is a list of the best options (table of runes listed below):

Loren (Light Cow Girl)

  • Role: Debuffer, control, and defense breaker.
  • Essential Runes: Violent/Revenge (SPD/HP%/HP%) or Swift/Broken (SPD/HP%/HP%).

With her consistent defense breaks, attack bar reduction, and healing block, Loren is a control powerhouse that ensures the enemy has minimal chances to strike back.

Veromos (Dark Ifrit)

summoners-war-veromos-dark-ifrit
  • Role: Cleanser and crowd control.
  • Essential Runes: Violent/Energy (SPD/HP%/HP%) or Swift/Energy.

Veromos purges harmful effects from allies with his passive and brings stuns to the table with his second skill, providing both utility and control.

Kro (Dark Inugami)

summoners-war-kro
  • Role: Damage dealer and brander.
  • Essential Runes: Violent/Revenge (SPD/CRIT Dmg%/ATk%) or Rage/Blade.

Kro shines with his ability to inflict massive damage, especially when the enemy has multiple debuffs. His branding also boosts the damage potential of the entire team.

Lyn (Light Amazon)

summoners-war-lyn-light-amazon
  • Role: Damage dealer based on enemy’s max HP.
  • Essential Runes: Rage/Blade (SPD/CRIT Dmg%/ATk%) or Fatal/Blade.

Lyn’s skills scale with the enemy’s max HP, making her a deadly adversary against bosses. She’s a go-to choice for speed teams aiming to nuke down high-HP targets.

Sabrina (Water Boomerang Warrior)

summoners-war-sabrina
  • Role: Damage dealer and defense breaker.
  • Essential Runes: Violent/Revenge (SPD/CRIT Dmg%/ATk%) or Fatal/Blade.

Sabrina synergizes exceptionally well with other Chakram Dancers, especially Talia. She provides consistent defense breaks, passive damage reduction, and high single-target nukes.

Artifacts

Artifacts can further boost your monsters’ performance in DB12. Put complete focus on adding additional substats that will boost the damage of your units.
