What Is & How to Unlock Castle Rush?
Castle Rush is a Guild Battle Event
Castle Rush is a guild battle event where you face Seven Knights and earn points. Rewards are distributed daily at 5 PM (PST) based on Guild Rank, determined by the total points earned by all members. Guild members who don't participate will not receive rewards.
Daily Battles Against Seven Knights
| Recommend | Monday | Tuesday | Wednesday |
|---|---|---|---|
| Magic Attack Attacks 3–4 Enemies | Rudy Guardian's Castle | Eileene Fodina Castle | Rachel Immortal Castle |
| Recommend | Thursday | Friday | Saturday |
| Physical Attack Attacks 3–4 Enemies | Dellons Death Castle | Jave Ancient Dragon's Castle | Spike Blizzard Castle |
| Recommend | Sunday | ||
| Physical/Magic Single-target Attack | Kris Hell Castle |
Castle Rush consists of 3 rounds that change daily, with a different Seven Knight as the final boss. After each battle, you earn points that can be exchanged for rewards.
Train Attackers With 3–4 Target Attacks
Except for Kris on Sundays, enemies have Damage Resistance to Physical/Magic, single-target, and 5-enemy attacks. Multi-target attacks are preferred, but since 5-enemy attacks are ineffective, focus on training attackers that hit 3–4 enemies.
 Tips! | With a 70-turn limit, firepower matters more than durability. You can also view each Castle Rush’s details anytime via 'Strategy' next to 'Enter.' |
|---|
Challenge 5 Times Daily
You can challenge Castle Rush up to 5 times per day. Rewards are given the next day based on your total accumulated points.
Unlocked Castle Rush at Guild Lv. 5
You can unlock Castle Rush by reaching Guild Level 5. To do this, you need to first join a guild or create your own.

Form Teams Effective Against The Boss
When preparing for Castle Rush, it's important to form teams that are effective against the boss of the day. Bring heroes with skills that counter the boss's abilities, such as debuff removals, defense reduction, or strong single-target damage, so adjust your lineup accordingly.
| Guardian's Castle | |
|---|---|
| Boss & Mechanics | Boss Rudy uses attacks that inflict Stun and grant Barriers. |
| Strategy | Bring a hero with Stun Immunity and a hero who can remove buffs, as damage to Barriers does not earn points. |
| Enemy Resistances | All enemies in Rudy's Castle Rush have Physical Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance. |
| Recommended Heroes | Use Magic damage heroes with Triple-Target Attack skills to maximize points and clear waves efficiently. |
| Fodina Castle | |
|---|---|
| Boss & Mechanics | Boss Eileene uses attacks that inflict Shock and grants All Damage Immunity to all allies whenever Rook uses a skill. |
| Strategy | Bring a hero with Shock Immunity and a hero who can reduce buff duration to remove the Damage Immunity buffs. |
| Enemy Resistances | All enemies in Eileene's Castle Rush have Physical Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance. |
| Recommended Heroes | Use Magic damage heroes with Triple-Target Attack skills to maximize points and efficiently clear waves. |
| Immortal Castle | |
|---|---|
| Boss & Mechanics | Boss Rachel uses attacks that inflict Burn, All Attack Reduction, and Defense Reduction. |
| Strategy | Bring a hero with Burn Immunity and a hero who can remove debuffs, as reduced Attack lowers the points you earn. |
| Enemy Resistances | All enemies in Rachel's Castle Rush have Physical Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance. |
| Recommended Heroes | Use Magic damage heroes with Triple-Target Attack skills to maximize points and clear waves efficiently. |
| Death Castle | |
|---|---|
| Boss & Mechanics | Boss Dellons uses high-damage Single-Target Attacks and inflicts Silence. Defeating one of your allies grants him a Damage Nullification buff. |
| Strategy | Bring a hero with Silence Immunity to block his high-damage attacks, and include defense-type heroes to minimize damage taken. |
| Enemy Resistances | All enemies in Dellons' Castle Rush have Magic Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance. |
| Recommended Heroes | Use Physical damage heroes with Triple-Target Attack skills to maximize points and clear waves efficiently. |
| Ancient Dragon's Castle | |
|---|---|
| Boss & Mechanics | Boss Jave uses attacks that inflict Stun and Dragonflame, and his Counterattacks gain +100% Crit Rate and +500% Crit Damage. |
| Strategy | Bring heroes with Stun Immunity and Burn Immunity, and a hero who can inflict Blind to prevent Jave's counterattacks from landing critical hits. |
| Enemy Resistances | All enemies in Jave's Castle Rush have Magic Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance. |
| Recommended Heroes | Use Physical damage heroes with Triple-Target Attack skills to maximize points and clear waves efficiently. |
| Blizzard Castle | |
|---|---|
| Boss & Mechanics | Boss Spike inflicts Freeze and gains the Force of Blizzard and Blizzard's Breath buffs whenever Chancellor uses a skill. |
| Strategy | Use a hero with Freeze Immunity and a hero who can remove buffs to cancel Spike's enhanced skills and reduce damage. |
| Enemy Resistances | All enemies in Spike's Castle Rush have Magic Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance. |
| Recommended Heroes | To maximize points, use Physical damage heroes with Triple-Target Attack skills. |
| Hell Castle | |
|---|---|
| Boss & Mechanics | Boss Kris uses attacks that inflict Death, and when Rook and Chancellor are hit, Kris's skill cooldowns are reduced. |
| Strategy | Bring a hero with Death Immunity and a hero who can Focus Target Kris when he has lower stamina, preventing Rook and Chancellor from granting cooldown reductions. |
| Enemy Resistances | All enemies in Kris's Castle Rush have Quintuple-Target Attack Resistance. |
| Recommended Heroes | Use heroes with Single-Target Attack skills to maximize points and efficiently defeat enemies. |

Recommended Heroes for Castle Rush
Castle Rush Hero Chart
*All heroes in the same tier share the same priority.
The heroes recommended for Castle Rush are listed above. It's generally best to raise SS and S-tier heroes, but if you don't have them, A-tier or lower heroes can serve as substitutes.
| ▼Status Effect Immunity | ▼3-4 Enemies Attackers | ▼Single-Target Attackers |
| ▼Versatile Supporters | ▼Other Key Heroes |
Status Effect Immunity Heroes
Start by raising one hero for each status effect immunity required in Castle Rush. Most of these heroes also overlap with those used in Power-Up Dungeons, though you'll need a separate hero specifically for Silence Immunity.
Silence Immunity
Silence Immunity is required for the Dellons battle on Thursday. Since magic damage is less effective against him, it's better to raise Jin instead of Cleo.
Stun Immunity
Stun Immunity is required for the Rudy battle on Monday and the Jave battle on Friday. Early on, the versatile Evan is sufficient, but Sieg is the ideal choice for increasing firepower.
Shock Immunity
| Only One | |||
|---|---|---|---|
Shock Immunity is required for the Eileene battle on Tuesday. Since Chloe is currently the only hero with this ability, make sure to raise her.
Burn Immunity
Burn Immunity is required for the Rachel battle on Wednesday and the Jave battle on Friday. Early on, Yui works well since she can also heal, but Ariel is the ideal choice for increasing firepower.
Freeze Immunity
Freeze Immunity is required for the Spike battle on Saturday. Since magic damage is less effective against him, it's better to raise Feng Yan instead of Lania.
Death Immunity
| Only One | |||
|---|---|---|---|
Death Immunity is required for the Kris battle on Sunday. Since Leo is currently the only hero with this ability, make sure to raise him.
3-4 Enemies Attackers
In many Castle Rush battles, attacks that hit 3–4 enemies are effective, while 5-enemy attacks are resisted. Make sure to raise at least one Physical and one Magic attacker with 3–4 target attacks.
Monday-Wednesday: Magic Attacks on 3-4 Enemies
Ruri
Miho
Sera
Ariel
Karma
Rin
Vanessa
CleoWith both skills dealing high-damage 3-enemy attacks, Ruri is the top recommended Magic attacker. On the other hand, Miho can serve as both an attacker and a supporter. Among Rare heroes, Sera is particularly recommended, but a well-raised Legendary hero can be used instead.
Thursday-Saturday: Physical Attacks on 3-4 Enemies
Taka
Feng Yan
Jin
Bi Dam
Rachel
KyleWith both skills dealing high-damage 3-enemy attacks, Taka is recommended for maximizing your score. If you don't have him, it's a good idea to prioritize raising the Rare hero Feng Yan.
| Tips! | Note that Rachel's first skill is a single-target attack until she reaches 6-star Transcendence. |
|---|
Single-Target Attackers
Pascal
Shane
Sieg
YuriOnly in the Kris battle on Sunday is there a risk when attacking targets other than the boss, making single-target attackers necessary. However, since Pascal and Shane, who are also useful in Raids, can be used, the Kris battle is easier to tackle than battles on other days.
| Tips! | Sieg has two single-target attacks, and his firepower boost and healing are also useful. He is valuable in the Rudy and Jave battles for his Stun Immunity, so raising him is highly recommended if you want to maximize your Castle Rush score. |
|---|
Versatile Supporters
Lina
Vanessa
Ace
Yui
EvanBiscuit and Lina are highly versatile supporters who can be used in any Castle Rush. If you don't have them, use Vanessa or Ace for Defense debuffs, and Yui or Evan for healing and durability.
Other Key Heroes per Castle
Recommended Heroes to Use
| Mon, Sat, Sun | Tue, Wed | Thu, Fri |
|---|---|---|
 BiscuitBuff Removal Weakness Hit Chance↑ |  MihoBuff Duration Reduction Debuff Removal |  RachelDamage Debuff |
Different mechanics need to be countered each day from Monday to Sunday, but raising Biscuit, Miho, and Rachel lets you handle all Castle Rush challenges. Ideally, you'll want to use these three, but until they're raised, use the other heroes mentioned below.
Buff Removal
Noho
Joker
Soi
KyleBuff Removal is effective in the Rudy battle on Monday and the Spike battle on Saturday. The heroes listed above are recommended for their multi-target attacks and strong support abilities, but Biscuit, who greatly boosts firepower, is the ideal choice.
Buff Duration Reduction
Rin
SeraIn the Eileene battle on Tuesday, Buff Duration Reduction is effective for removing her Damage Immunity. Raise at least one of the heroes above with a 3–4 enemy attack, though Miho, who can serve as both a supporter and sub-attacker, is the recommended choice.
Debuff Removal
Lucy
ChloeIn the Rachel battle on Wednesday, use Debuff Removal to counter Attack and Defense reductions. Early on, Lucy or Chloe, also useful in Raids and Power-Up Dungeons, are good options. Ultimately, Miho is recommended, as she can remove debuffs from the back row at 2-star Transcendence.
Taunt or Attack Debuff
LiIn the Dellons battle on Thursday, to avoid being defeated by his high-damage single-target skill, it's recommended to use Li, who has both Taunt and Physical Damage Immunity. As your party grows stronger, you can also survive using Rachel's Attack Debuff.
| Tips! | Increase Rachel's Weakness Hit Chance or raise her to 6-star Transcendence, where her first skill hits 3 enemies, to ensure her All Attack Reduction affects Dellons. |
|---|
Blind or Attack Debuff
MayThe Jave battle on Friday features powerful Critical Attacks, so it's recommended to use May, who can inflict Blind to cause him to Miss. As in the Dellons' battle, a stronger party can also survive using Rachel's Attack Debuff.
| Tips! | Increase Rachel's Weakness Hit Chance or raise her to 6-star Transcendence, where her first skill hits 3 enemies, to ensure her All Attack Reduction affects Dellons. |
|---|
Focus Target or Weakness Hit Chance Boost
AsuraIn the Kris battle on Sunday, damaging anyone other than Kris reduces his skill cooldowns. You can either use Asura to apply Focus Target to Kris or accept some Cooldown Reduction and focus on boosting your score by increasing your attackers' Weakness Hit Chance with Biscuit.
| Tips! | When using Biscuit, it's ideal for your attacker's Weakness Hit Chance to be around 50%. Additionally, the higher the Weakness Hit Chance of your other party members, the more you can reduce the risk of Cooldown Reduction. |
