Eileene in Fodina Castle uses attacks that inflict Shock and grant Berserk on herself. Meanwhile, Fodina Rook and Chancellor can also inflict Shock and possess Damage Resistance, making this stage difficult to clear without the right team setup.

Fodina Castle Best Heroes

Shock Immunity

Only One
Chloe

Chloe is the only hero with Shock Immunity, making her a key hero for surviving in Fodina Castle until the final turn. Chloe also provides an All Attack Boost, Debuff Removal, and a chance to inflict Unable to Recover.

Magic Attacks on 3-4 Enemies

At Least One
Ruri	Miho	Sera	Ariel
Karma	Rin	Vanessa	Cleo

All enemies in Fodina Castle have Damage Resistance against Physical attacks, single-target skills, and 5-target skills, so focus on using magic attacks that hit 3–4 enemies. Ruri is the top recommendation, but if you don't have her, it's best to enhance the Sera instead.

Buff & Debuffs

Versatile Support Heroes
Biscuit	Lina	Miho	Vanessa
Yeonhee	Ace	Ariel	Noho

When you enter the third round, use buffs and debuffs to increase your attacker's damage. It's recommended to apply buffs and debuffs with longer durations first.

Buff Duration Reduction

At Least One
Miho	Rin	Sera

When Rook uses a skill, he grants Damage Immunity to the enemy. You won't be able to deal any damage at all, preventing you from increasing your score, so remove it immediately by shortening it with Buff Duration Reduction.

Team Formation Examples

Front Row	Front Row	Front Row	Front Row	Back Row

Fodina Castle Tips & Strategy

Form Teams Effective Against Eileene

The key to victory is bringing heroes with Magic Attacks with 3-Enemy Target skills, Shock Immunity and Debuffer/Buff Duration Reduction to counter Eileene, so adjust your lineup accordingly.

Use Protective Formation

Protective Formation is the recommended setup for Fodina Castle. 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 investment 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.

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 'Barrier', then use priority skills manually to gain the upper hand.

Enhance Your Hero

Enhance your heroes' skills, ultimate, and power-up to +5. Prioritizing tanks and healers to boost their effectiveness and utility. Skill & Ultimate Enhancement materials can be obtained from Story Event rewards, the Shop, and the Infinite Tower.

How to Get the Highest Score

Use Magic Heroes with 3-Target Skills

All enemies in Fodina Castle have Physical Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance buffs. To increase damage output and achieve a high score, use Magic-type heroes with Triple-Target Attack skills.

Sustain is Optional

The core mechanic of Castle Rush is to maximize total damage within the turn limit, as scores are based on the cumulative damage dealt before the final turn. If your team can endure without heavy support, focus on offense and buff duration reduction/debuff instead to maximize score.

Tips!	If your team struggles, bring a healer, buff remover, or crowd control to survive until the final turn.
