Check Enemy Information

You can check the enemy's strengths, weaknesses, and lineup in 'Enemy Information'. Use this to plan which Heroes to bring so you can counter both the targets and the boss effectively. A good strategy is to build teams that exploit elemental advantages, bring debuff removals to stay safe, and include damage dealers.
Power Up your Heroes, Equipment & Formation
After selecting the right Heroes for a specific Castle, make sure to Power Up them and enhance the Formation you plan to use. Proper preparation ensures your team can deal maximum damage and earn the highest points for your guild.

Recommended Heroes for Castle Rush
Guardian's Castle
Rudy uses attacks that inflict Stun and grant Barriers to himself, preventing damage from being scored. Bring a hero with Stun Immunity and another who can remove buffs to bypass his Barriers. All enemies in Rudy's Castle Rush have Physical Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance, so using Magic Triple-Target attackers is recommended
Recommended Hero | Details |
---|---|
![]() | A Magic hero with a skill barrage that strikes three enemies twice. Thanks to her Magic Damage Boost, her damage steadily increases during combat and spikes further when hitting weaknesses, making her an ideal DPS for this castle. |
![]() | Since Rudy inflicts Stun, it's best to bring a hero with Stun Immunity, such as Evan. In addition to protecting allies from Stun, Evan also provides a Barrier and Defense Boost to the entire team. |
![]() | Rudy frequently maintains his Barrier, which can prevent your attacks from dealing damage. Joker can counter this with his magic attack skill that strikes three enemies and has a 100% chance to remove 2 buffs from each target. |
Fodina Castle
Eileene inflicts Shock and grants All Damage Immunity to all allies whenever Rook uses a skill. Bring a hero with Shock Immunity and another who can reduce buff duration to remove her Damage Immunity buffs. All enemies have Physical Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance, so using Magic Triple-Target attackers is recommended.
Recommended Hero | Details |
---|---|
![]() | She is a Magic Hero with Reduced Buff Duration. Her skill also targets 4 enemies, so its damage is not reduced. She is suitable because Skill Enhancement and Transcend are not required. |
![]() | A Magic Hero with Reduced Buff Duration. Skill Enhancement and Transcend are not required, but since her skill is a 5-enemy AoE attack, it won't deal damage. She is suitable enough to be considered for those who find it troublesome to raise Sera. |
![]() | She has Reduced Buff Duration, but it's a Transcend effect, so she can't be used unless she's raised. On top of being a Physical Hero, her skill targets a Single Enemy, making it a game of luck, so she is not highly recommended. |
![]() | He has Reduced Buff Duration, but since his attacks are 5-enemy AoE and Physical damage, almost no damage gets through, making him unsuitable. |
Immortal Castle
Rachel inflicts Burn, All Attack Reduction, and Defense Reduction, making extended battles highly demanding. To mitigate these effects, include a hero with Burn Immunity and another with debuff removal. Additionally, a hero with continuous healing is recommended to offset Burn damage over time.
Recommended Hero | Details |
---|---|
![]() | Miho applies Magic Vulnerability and Buff Reduction to enemies, boosting team DPS. She also provides Life Drain, which is especially useful against Burn-inflicting enemies. |
![]() | 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. |
![]() | Lucy has a skill that heals all allies and removes 2 debuffs. However, since her healing scales with Defense, the healing output may be lower. |
![]() | Yui is the top recommended support for Immortal Castle. She provides Burn Immunity and two turns of continuous healing, greatly increasing team survivability. |
Death Castle
Dellons specializes in high-damage Single-Target attacks and inflicts Silence. When one of your allies is defeated, he gains a Damage Nullification buff. Use a hero with Silence Immunity to block his disabling attacks, and bring defense-type heroes to withstand his powerful single-target damage. For scoring, rely on Physical Triple-Target heroes.
Recommended Hero | Details |
---|---|
![]() | A Physical attacker who inflicts Attack Reduction, Damage Reduction, and Defense Reduction on enemies. With added Physical Vulnerability and Weakness Chance Boost, she not only deals strong Physical damage herself but also enables the team to hit much harder. |
![]() | Bi Dam is the most recommended DPS for Death Castle. He applies Bleed and can detonate it for burst damage. Even if Dellons applies Silence, Bleed continues to deal damage over time, ensuring consistent DPS output. |
![]() | For Silence Immunity, Cleo is an excellent choice. Like Jin, she provides Silence Immunity to all allies for two turns. Additionally, her Poison skills inflict damage over time, offering both utility and sustained DPS. |
![]() | Optionally, you can include Li in your team. As a defense-type hero, he can taunt enemies, redirecting attacks toward himself and keeping your DPS and Support heroes safe from Dellons' high-damage strikes. |
Ancient Dragon's Castle
For Jave, he inflicts Stun and Dragonflame, with Counterattacks gaining +100% Crit Rate and +500% Crit Damage. Bring heroes with Stun and Burn Immunity, plus one who can inflict Blind to block critical counterattacks. With all enemies having Magic Resistance and Attack Resistances, Physical Triple-Target attackers are recommended.
Recommended Hero | Details |
---|---|
![]() | For Stun Immunity, use Sieg, who provides minor healing and a Physical Attack Boost to back-row allies. You can also use Evan, who grants Stun Immunity and a Barrier to all allies. |
![]() | Ariel not only has a chance to inflict Blind on enemies but also provides Burn Immunity to all allies, making her essential against Jave. Since her damage is low and she relies on Magic attacks, pair her with a strong Physical DPS. |
![]() | If your team has a strong healer but lacks utility, use May. Her skill can inflict Blind on Jave, with a chance to apply Burn, Poison, and Bleed, while also granting a Physical Damage Boost to all allies. |
![]() | Bi Dam works great as Physical attacker thanks to his self Physical Damage Boost. Alternatively, you can use Feng Yan and Taka. |
Blizzard Castle
Spike inflicts Freeze and gains Force of Blizzard and Blizzard's Breath buffs whenever Chancellor uses a skill. Bring a hero with Freeze Immunity and one who can remove buffs. With all enemies having Magic Resistance and Attack Resistances, Physical Triple-Target attackers are recommended.
Recommended Hero | Details |
---|---|
![]() | Feng Yan is the better choice, as he performs a Physical attack and grants All Damage Immunity to himself. In comparison, Lania is a Magic attacker, and since all enemies have Magic Resistance, she is less effective in this field. |
![]() | Soi grants Damage Boost and Inflict Buf removal which is useful against Spike's Blizzard's breath. Alternatively, you can use Joker or Noho, but they use magic attacks. |
![]() | When facing Spike, a Physical Triple-Target attacker is essential. Taka is an excellent choice, boasting two raw Physical Damage skills and additional Crit Damage. Pair him with a decent support for survivability. |
Hell Castle
For Kris, he inflicts Death, and when Rook and Chancellor are hit, his skill cooldowns are reduced. Bring a hero with Death Immunity and one who can Focus Target Kris when his stamina is low to prevent cooldown reductions. All enemies have Quintuple-Target Attack Resistance, so using heroes with Single-Target Attack skills is recommended.
Recommended Hero | Details |
---|---|
![]() | Leo is a must-have for Hell Castle, as he is currently the only hero who grants Death Immunity to all allies. |
![]() | Asura is also essential. Since Kris's skill cooldowns are reduced whenever Rook and Chancellor are hit, use 'Focus Target' to concentrate all attacks on Kris and prevent this. |
![]() | Single-Target Attack heroes are most effective against Kris. Pascal is a strong choice, dealing heavy damage with self-buffs that reset skills and a Defense-Ignoring ability. Alternatively, you can use Jupy or Shane. |
