Enemy Info

Round 1
Rook	Chancellor	Rook
Round 2
Rook	Chancellor	Rook
Round 3
Rook	Spike	Chancellor

In Blizzard Castle, Spike uses both single and multi-target skills that can inflict Freeze and deal devastating CRIT damage to units afflicted by the Blizzard debuff. Meanwhile, Blizzard Castle's Rook and Chancellor can also inflict Freeze and apply the Blizzard debuff, making this stage particularly difficult to clear without a suitable team setup.

Blizzard Castle Best Heroes

Freeze Immunity

Feng Yan	Feng Yan is highly recommended over Lania. A strong F2P Main DPS with Freeze Immunity, he deals high-scaling Physical attacks and grants himself All Damage Immunity. Recommended Set: Assassin/Gatekeeper
Lania	Lania is a viable alternative if you don’t have Feng Yan, but keep in mind that she relies on Magic attacks. While her Freeze skill can be helpful, she contributes little to the overall score. Recommended Set: Paladin/Gatekeeper

Buff Removal

Biscuit	Biscuit provides excellent utility with her Defense Debuff, Buff Removal, and Weakness Hit Chance Boost, making her a strong addition to almost any team. Recommended Set: Gatekeeper
Joker	Aside from Buff Removal, Joker can inflict Stun on an enemy and grant Crit Damage Boost to all allies. Keep in mind he's a Magic attacker and contributes little to the overall score. Recommended Set: Paladin/Gatekeeper
Soi	Soi is a Physical attacker who grants a Damage Boost and inflicts Buff Removal and Bleed, making her effective against Blizzard's breath debuff. Recommended Set: Paladin/Gatekeeper

Continuous Healing

Lina	Lina provides a Damage Boost and Continuous Healing. With Effect Resist Boost, it decreases the chance of being inflicted with Stun. Lina doesn't require any Skill Enhancement. Recommended Set: Paladin/Gatekeeper
Yui	Yui is also the top recommended support for most stages. She provides continuous healing, greatly boosting team survivability. Enhancing her healing skill for an extra turn is highly recommended. Recommended Set: Paladin/Gatekeeper

Damage Dealer (DPS)

Taka	A multi-hit Physical attacker who deals bonus damage to low-HP enemies and increases Physical damage taken by the top three attackers when striking twice. Recommended Set: Assassin
Bi Dam	He applies Bleed and detonates it for burst damage. Even if Spike applies Freeze, Bleed continues to deal damage over time, ensuring consistent DPS output. Recommended Set: Assassin/Vanguard
Feng Yan	F2P players gain more from using Feng Yan. In addition to providing Freeze Immunity, he deals high-scaling Physical damage and grants himself All Damage Immunity. Recommended Set: Assassin

Sub-DPS & Utility

Rachel	A Physical attacker who inflicts debuffs and boosts Physical Vulnerability and Weakness, dealing strong damage while empowering the team. Recommended Set: Bounty Tracker
Ace	He inflicts Defense Reduction, Physical Vulnerability, Buff Duration Reduction, and Reduced Incoming Healing, creating opportunities for your team to deal higher damage. Recommended Set: Vanguard/Gatekeeper

All enemies in Spike's Blizzard Castle have Magic Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance buff. To counter this, Heroes with Physical damage and Triple-Target Attack skills are recommended.

Blizzard Castle Tips & Strategy

Form Teams Effective Against Spike

The key to victory is bringing Physical attackers with 3-Enemy Target skills, along with Freeze Immunity and Buff Removal to counter Spike, so adjust your lineup accordingly.

Use Protective Formation

Protective Formation is the recommended setup for Blizzard 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 Physical Heroes with 3-Target Skills

All enemies in Spike's Blizzard Castle have Magic Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance buff. To increase damage output and achieve a high score, use Physical-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 removal instead to maximize score.

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