Guardian's Castle Tips & Strategy
Form Teams Effective Against Rudy
The key to victory is bringing heroes with Magic Attacks, 3-Enemy Target skills, Stun Immunity and Buff Removal to counter Rudy, 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 Buff Removal. |
| 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. |
Use Protective Formation
Protective Formation is the recommended setup for Guardian's 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 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. |
|---|
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 Guardian's Castle possess 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/debuff instead to maximize score.
| Tips! | If your team struggles, bring a healer, buff remover, or crowd control to survive until the final turn. |
