Tips for Clearing Blizzard Castle (Saturday) Spike

Freeze Immunity Is a Must

Freeze Immunity Hero List
Lania	Feng Yan

The enemy will inflict Freeze. Without a countermeasure, you'll be at a serious disadvantage, so make sure to include a hero with Freeze Immunity. Since magic damage doesn't land well here, Feng Yan is a better choice than Lania.

Use Physical Attacks That Hit 3-4 Targets

At Least 1 of the Following
Ryan	Sunran	Taka	Bi Dam
Rachel	Kyle	Feng Yan	Jin

All enemies in Blizzard Castle reduce incoming damage from magic attacks, single-target skills, and 5-target skills, so attack with physical attacks that hit 3-4 targets. Ryan, Sunran, and Taka are best, but if you don't have them, it's better to raise the Rare hero Feng Yan instead.

Tips!	Keep in mind that Rachel's Skill 1 remains a single-target attack until Transcendence 6.

First, Clear Rounds 1-2 Quickly

Castle Rush is played over 3 rounds, and the boss Spike appears in the 3rd round. Since you need to raise your score as much as possible within 70 turns, clear Rounds 1-2 quickly using your attackers' attacks.

Boost Damage With Buffs and Debuffs

Examples of Buff/Debuff Heroes
Biscuit	Lina	Rachel	May
Ace

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

Use Buff Removal After Chancellor's Skill

Any 1 of the Following
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 Spike is buffed, an ice effect appears around him. This is a visual cue that the buff is still active.

Whittle Down HP With Attackers

Once buffs and debuffs are set up, use your back-row attackers to whittle down the enemies' HP. Even if you used their skills in Rounds 1-2, they'll likely be ready to use again by the time you've finished setting up.

Progress Enhancement, Evolution, and Other Training

Progressing through Enhancement, Evolution, and Ultimate Enhancement is important for raising your score. In particular, prioritizing your attackers' Ultimate Enhancement and Skill Enhancement is best, since it makes it much easier to boost your score.

Spike's HP is high at 60,000, making it easy to take advantage of HP-proportional attacks, so if Sunran is at Transcendence 6, this party will help you rack up a higher score. If she's below Transcendence 6, use the Taka party instead.

Target Stats

Hero	Target Stats	Notes
	100%	Best to lean toward durability since she's a Magic-type hero
	80%+	Increases the infliction rate of status ailment rings
	Needs Adjustment	Keep lower than Sunran and Ryan
	80%+	For boosting your score
	200%+	The higher, the better
	50%+	70%+ with Rachel's buff
	Needs Adjustment	Keep lower than Sunran and Ryan
	80%+	For boosting your score
	200%+	The higher, the better
	60-80%	80-100% with her Passive Skill
	5000+	1st-2nd highest in the party
	80%+	The higher, the less your score varies
	200%+	The higher, the better
	0%	Weakness Hit Chance reaches 100% at T6
	-	4th-highest in the party
	4500+	1st-2nd highest in the party
	80%+	The higher, the less your score varies
	200%+	The higher, the better
	20-40%	81-100% with Biscuit/Rachel's buffs
	-	5th-highest in the party

Setting the turn order so Sunran goes 4th and Ryan goes 5th improves the timing of Sunran's Awakening Skill activation, letting her attack while Biscuit's buff is still active.

If any hero besides Feng Yan keeps getting knocked out, try raising their Defense or HP through Potential or gear.

Best Equipment & Rings

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

Since Biscuit is a Spellweaver, equipping a status ailment ring is recommended for her. Also, since Feng Yan tends to get knocked out easily, giving her a Ring of Authority can provide some peace of mind.

Tips!

Refining into a Ring of Authority is just an ideal goal. Since it has low versatility and becomes hard to use elsewhere, you don't need to force yourself to refine it.

Best Pets

Ideal	Alt.	Alt.	Low Rarity
Windy	Eirin	Igris	Sherry

For pets, Windy, who can inflict Boss Vulnerability, is the best pick. If you don't own her, Eirin or the rare Collaboration pet Igris can be used as a substitute.

Alternative Heroes

Main Pick	Alternative Heroes	Notes
	Lania	Alt for Freeze Immunity
	Eileene	Alt for Buff/Debuff
	Taka	Alt for 3rd Physical Attacker
	Kyle	Alt for 4th Physical Attacker

If Sunran is below Transcendence 6, swapping her out for Taka or Eileene may boost your score in some cases. Lania also works fine for Freeze Immunity, but if you want to push your score even higher, use the physical hero Feng Yan instead.

Sunran's Demon Face gains +3 stacks with each wave, so you can clear Wave 2 via the automatic skill activation at 6 stacks.

Delaying Ryan's Skill 2, which normally triggers between turns 40 and 50, to turn 48 lets you absorb Spike's skill with Damage Immunity instead, raising your survival rate.

Depending on how each hero is built, using Eileene instead of Sunran may boost your score in some cases. If so, Biscuit takes over the Buff Removal role. Try both comps and use whichever gives you the higher score.

Target Stats

Hero	Target Stats	Notes
	100%	As a magic-type hero, a bulkier build is best.

	20%～40%	81-100% with Biscuit/Rachel's buffs.
	-	Keep 3rd-4th within the party.

Setting Ryan and Rachel's turn order to 3rd-4th lets them attack without Biscuit's buff expiring.

If any hero other than Feng Yan is getting knocked out, try boosting Defense or HP through Potential or equipment.

Best Equipment & Rings

Hero	Equipment	Ring (Craft)
Biscuit
Feng Yan
Rachel
Eileene
Ryan

Biscuit is best equipped with the Spellweaver set and a Status Ailment ring. Feng Yan also tends to get knocked out easily, so equipping the Ring of Authority provides some extra peace of mind.

Tips!	Refining the Ring of Authority is only ideal, not mandatory. It has limited versatility and becomes hard to use for other setups, so you don't have to force yourself to refine it.

Best Pets

Ideal	Alt.	Alt.	Low Rarity
Windy	Eirin	Igris	Sherry

For pets, Windy, who can inflict Boss Vulnerability, is the best pick. If you don't own her, Eirin or the rare Collaboration pet Igris can be used as a substitute.

Alternative Heroes

Main Pick	Alternative Heroes	Notes
	Lania	Alt for Freeze Immunity
	Sunran	Alt for Buff/Debuff
	Taka	Extra Attacker
	Kyle	Extra Attacker

If Sunran is Transcendence 6 or above, swapping Eileene out for Sunran may boost your score in some cases. Lania also works fine for Freeze Immunity, but if you want to push your score even higher, use the physical hero Feng Yan instead.

Early on, prioritize stacking Eileene's Defense Reduction; once it's fully stacked, prioritize using Rachel's and Ryan's skills. Don't forget to use Biscuit's Buff Removal when Spike shows the ice animation cue.

This is an example physical party built around two attackers, Taka and Ryan. If Sunran is below Transcendence 6, this comp is also worth considering.

	200%～	The higher, the better.
	20%～40%	81-100% with Biscuit/Rachel's buffs.

For everyone except Biscuit, boost Crit Rate, Crit Damage, and Weakness Hit Chance.

Since Biscuit is a magic-type hero, she doesn't deal much damage, so it's best to boost her durability and Effect Hit Rate.

Best Equipment & Rings

Hero	Equipment	Ring (Craft)

Since Biscuit is a Spellweaver, equipping a status ailment ring is best. Also, since Feng Yan is easily knocked out, equipping the Ring of Authority will give you peace of mind.

Tips!	Refining the Ring of Authority is only ideal - it has low versatility and becomes harder to use elsewhere, so you don't need to force yourself to refine it.

Best Pets

Ideal	Alt.	Alt.	Low Rarity

For pets, Windy, who can inflict Boss Vulnerability, is the best choice. If you don't have her, use Yeonji or the collaboration rare pet Igris as a substitute.

	Lania	Freeze Immunity Alternative
	Eileene	Buff/Debuff Alternative
	Sunran	Alt. 4-Physical-Attacker Team
	Kyle	Alt. 4-Physical-Attacker Team

There are cases where swapping in Sunran will increase your score if she's Transcendence 6 or higher. Lania works fine for Freeze Immunity, but if you want to push your score even higher, use the physical hero Feng Yan instead.

To keep your attackers from getting knocked out, deal damage while making the most of Taka's on-skill-use Damage Nullification and Ryan's Physical Attack Reduction.

When ice effects appear around Spike, don't forget to use Biscuit's Buff Removal.
