Tips for Clearing Saturday Castle Rush Spike

Freeze Immunity is a Must

List of Freeze Immunity Heroes
Lania	Feng Yan

The enemy inflicts Freeze. Without countermeasures, you'll be at a serious disadvantage, so make sure to include a hero with Freeze Immunity in your team. Magic damage doesn't land well here, so Feng Yan is a better pick than Lania.

Use Physical Attacks that Hit 3-4 Targets

Include at Least One
Ryan	Sunran	Taka	Bi Dam
Rachel	Kyle	Feng Yan	Jin

All enemies in Blizzard Castle reduce Magic Attacks, Single-Target Skills, and 5-Target Skills, so attack with physical attacks that hit 3-4 targets. Ryan, Sunran, and Taka are recommended, but if you don't have them, it's better to raise the Rare hero Feng Yan.

Tips!	Note that Rachel's Skill 1 remains a single-target attack until she reaches 6th Transcendence.

Clear Rounds 1-2 Quickly First

Castle Rush has 3 rounds, with the boss Spike appearing in Round 3. Since you need to maximize your score within 70 turns, clear Rounds 1-2 quickly using your attackers' attacks.

Boost Damage with Buffs and Debuffs

Example Buff/Debuff Heroes
Biscuit	Lina	Rachel	May
Ace

Once you reach Round 3, boost your attackers' damage with buffs and debuffs. It's best to apply buffs/debuffs with the longest duration first.

Use Buff Removal After Chancellor's Skill

Choose One
Biscuit	Soi	Kyle	Vanessa
Joker	Noho

When Chancellor uses his skill, Spike's skill gains 100% Crit Rate + 500% Crit Damage. Use Buff Removal early, before Spike gets to use his skill.

Tips!	When the buff is applied, an icy visual effect appears around Spike. This is a sign that the buff is still active.

Whittle Down HP with Your Attackers

Once buffs and debuffs are set up, whittle down the enemy's HP with the attackers in your back row. Even if you used their skills in Rounds 1-2, in most cases their skills will be ready to use again by the time you've set the stage.

Progress Enhancement, Evolution, and Other Upgrades

To boost your score, upgrading through Enhancement, Evolution, and Ultimate Enhancement is important. In particular, prioritizing Ultimate Enhancement and Skill Enhancement for your attackers is recommended, as it makes it much easier to raise your score.

Recommended Team Examples

Intermediate-to-Advanced Sunran Team

Team Formation: Balanced Formation

Biscuit

Sunran

Feng Yan

Ryan

Rachel

Buff/Debuff

Main DPS

Freeze Immunity

Main DPS

Sub-DPS
Buff/Debuff

Spike's HP is high at 60,000, making it easy to take advantage of HP-scaling attacks, so if Sunran is at 6th Transcendence, this team will raise your score more easily. If she's below 6th Transcendence, use the Taka team instead.

Target Stats

Hero	Target Stats	Notes
	100%	Recommended to build for survivability since it's a Magic-type hero
	80%+	Increases proc rate of status effect rings
	Needs Adjustment	Keep lower than Sunran and Ryan
	80%+	For score boost
	200%+	Higher is better
	50%+	70%+ with Rachel's buff
	Needs Adjustment	Keep lower than Sunran and Ryan
	80%+	For score boost
	200%+	Higher is better
	60-80%	80-100% with passive
	5000+	1st-2nd highest in the team
	80%+	Higher reduces score variance
	200%+	Higher is better
	0%	100% Weakness Hit Chance at 6th Transcendence
	-	4th highest in the team
	4500+	1st-2nd highest in the team
	80%+	Higher reduces score variance
	200%+	Higher is better
	20-40%	81-100% with Biscuit/Rachel's buffs
	-	5th highest in the team

Setting the turn order so Sunran goes 4th and Ryan goes 5th improves the timing of Sunran's Awakening Skill activation, letting you attack without Biscuit's buff running out.

If any hero besides Feng Yan gets killed, try raising Defense or HP through Potential or Equipment.

Recommended Equipment & Rings

Hero	Equipment	Ring (Refine)
Biscuit
Feng Yan
Rachel
Sunran
Ryan

Biscuit uses the Spellweaver set, so equipping status effect rings is recommended. Also, since Feng Yan tends to get killed easily, equipping the Ring of Authority provides some peace of mind.

Tips!	Refining the Ring of Authority is just the ideal, though. It has low versatility and becomes hard to use elsewhere, so it's fine not to force the refine.

Recommended Pets

Ideal	Alternative	Alternative	Low Rarity
Windy	Eirin	Igris	Sherry

Windy, who can inflict Boss Vulnerability, is the best pet to use. If you don't have it, use Eirin or the collab Rare pet Igris as a substitute.

Alternative Heroes

Main Pick	Alternative Hero	Notes
	Lania	Freeze Immunity alternative
	Taka	Alternative 3-target physical attacker
	Kyle	Alternative 4-target physical attacker

If Sunran is below 6th Transcendence, swapping her for Taka may increase your score. Lania works fine for Freeze Immunity, but if you want to squeeze out even more score, use the physical-type Feng Yan instead.

Sunran's Demon Face stacks +3 more each time the Wave advances, so you can clear Wave 2 once the auto-triggered skill activates at 6 stacks.

By delaying Ryan's Skill 2 (originally used around turns 40-50) to turn 48, you can block Spike's skill with Damage Immunity, increasing your survival rate.

Intermediate-to-Advanced Taka Team

Team Formation: Balanced Formation

Biscuit

Taka

Feng Yan

Ryan

Freeze Immunity

This is an example physical team that attacks with two attackers, Taka and Ryan. If Sunran is below 6th Transcendence, this team composition is recommended.

Raise Crit Rate, Crit Damage, and Weakness Hit Chance for everyone except Biscuit.

Biscuit is a Magic-type hero and her damage doesn't land well, so it's recommended to raise her survivability and Effect Hit Rate instead.

To keep your attackers from being killed as much as possible, deal damage while making use of Taka's on-skill-activation Damage Immunity and Ryan's Physical Attack Reduction.

When the icy visual effect appears around Spike, don't forget to use Biscuit's Buff Removal.
