Tips for Beating Friday Castle Rush Jave

Burn Immunity and Stun Immunity are a Must

Burn Immunity Hero List
Ariel	Yui	Ryan

Stun Immunity Hero List
Evan	Sieg

The enemies inflict Dragonflame and Stun, so be sure to include heroes with Burn Immunity and Stun Immunity in your team. Ryan, who can reduce cooldowns, and Sieg, who can boost Physical Attack, are recommended, but if they're not trained yet, Evan or Yui can be used as substitutes.

Use Physical Attacks Targeting 3-4 Enemies

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

All enemies in Ancient Dragon's Castle have Magic Attack Resistance, Single-Target Attack Resistance, and Quintuple-Target Attack Resistance, so attack with physical attacks that target 3-4 enemies. Taka, Ryan, and Sunran are especially recommended, but if you don't have them, it's better to train the Rare hero Feng Yan instead.

Tips!	Keep in mind 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 Jave appearing in Round 3. Since you need to maximize your score within 70 turns, use your Main DPS and Sub-DPS to clear Rounds 1-2 quickly.

Prioritize Blind, Barriers, DPS Debuffs, and More

Any 1 of the Following
Ryan	Rachel	Evan	May

Once you reach Round 3, use Ryan or May's Blind, Evan's Barrier generation, and Rachel's DPS Debuff as countermeasures against Jave's critical attacks. Ideally, enhance Ryan's Skill 1 to give him Physical Attack Reduction.

Tips!	Train Rachel to 6th Transcendence, where Skill 1 becomes a 3-target attack, so that her DPS Debuff lands on Jave.

Increase Damage with Buffs and Debuffs

Buff/Debuff Hero Examples
Biscuit	Lina	Rachel	May
Ace

Next, use buffs and debuffs to increase your attackers' damage. It's recommended to apply the buffs/debuffs with the longest duration first.

Wear Down Enemy HP with Your Attackers

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

Advance Enhancement, Evolution, and Other Upgrades

To increase your score, training such as Enhancement, Evolution, and Ultimate Enhancement is important. In particular, it's recommended to prioritize Ultimate Enhancement and Skill Enhancement for your attackers, as this makes it much easier to boost your score.

Best Team Examples

Intermediate-to-Advanced Taka Team

Team Comp Formation: Balanced

Biscuit

Taka

Sieg

Ryan

Rachel

Buff/Debuff

Main DPS

Buff
Stun Immunity

Main DPS
Burn Immunity
Blind

Sub-DPS
Debuff

This is a physical team example that attacks with Taka and Ryan as its two attackers. If your Taka is more built up than your Sunran, this build is recommended.

Tips!	Jave has lower Max HP compared to Dellons and Spike, so Sunran's HP-based attack is a bit less effective here.

Target Stats

Hero	Target Stats	Notes
	100%	Recommended to build tanky since she's a Magic-type hero
	80%~	Increases status effect ring application rate
	Needs adjustment	Lower than Taka and Ryan
	80%~	For score boost
	200%~	The higher, the better
	50%~	70%+ with Rachel's buff
	Needs adjustment	Lower than Taka and Ryan
	80%~	For clearing Wave 2 and boosting score
	200%~	For clearing Wave 2 and boosting score
	60%~80%	80-100% with passive
	4500~	Should be 1st-2nd highest in the party
	80%~	The higher, the less score variance
	200%~	The higher, the better
	20%	81% with Biscuit/Rachel's buffs
	-	Should be 5th in the party
	4500~	Should be 1st-2nd highest in the party
	80%~	The higher, the less score variance
	200%~	The higher, the better
	20%	81% with Biscuit/Rachel's buffs
	-	Should be 4th in the party

It's recommended to lower attackers' Speed so they can receive buffs for longer, but if Ryan is 5th, his cooldown reduction won't line up properly, so make Ryan 4th and Taka 5th.

Tips!	If your attackers are getting knocked out, raising DEF or HP through Hero Potential or equipment is also an option.

Best Equipment & Rings

Hero	Equipment	Ring (Refine)
Biscuit
Sieg
Rachel
Taka
Ryan

Biscuit is a Spellweaver, so a status ailment ring is recommended for her. The others should use Avenger gear, but that makes them easier to take down, so at least equip Sieg with a Ring of Authority. Depending on the situation, a Ring of Authority can also be an option for the other heroes.

Recommended Pets

Ideal	Alternative	Alternative	Low Rarity
Windy	Eirin	Igris	Sherry

For pets, Windy, who can inflict Boss Vulnerability, is the most recommended. If you don't have her, use Eirin or the collab rare pet Igris as a substitute.

Alternative Heroes

Main	Alternative Hero	Notes
	Yui	Early-game Burn Immunity
	Evan	Early-game Stun Immunity
	Feng Yan	Early-game 3-Target Physical Attacker
	Sunran	Alternative 3-Target Physical Attacker

If Sunran is more developed than Taka, swapping her in may increase your score. If Ryan or Sieg aren't developed yet, it's fine to swap in Yui or Evan, who are used in the Power Up Dungeon and Raids.

To make the most of the Damage Immunity granted when Taka uses her skill, the trick is to alternate skill usage between Taka and Ryan as much as possible.

If your attackers end up getting defeated late in the battle, adjusting the timing of Ryan's Physical Attack Reduction skill is also an option.

Intermediate to Advanced Sunran Team

Team Composition (Formation: Balanced)

Biscuit

Sunran

Sieg

Ryan

Rachel

Buff/Debuff

Main DPS

Buff
Stun Immunity

Main DPS
Burn Immunity
Blind

Sub-DPS
Debuff

This is an example Physical team that attacks with Sunran and Ryan as its two attackers. If Sunran is more developed than Taka, this composition is recommended instead.

Tips!

Compared to Dellons and Spike, Jave has lower max HP, which makes Sunran's HP-based attack somewhat less effective. Depending on your investment, Taka may score higher instead.

Target Stats

Hero	Target Stats	Notes
	100%	Recommended to lean tanky, since she's a Magic-type hero
	80%+	Boosts status ailment ring proc rate
	Needs adjustment	Lower than Taka and Ryan
	80%+	For score boost
	200%+	The higher, the better
	50%+	70%+ with Rachel's buff
	Needs adjustment	Lower than Taka and Ryan
	80%+	For clearing Wave 2 and boosting score
	200%+	For clearing Wave 2 and boosting score
	60-80%	80-100% with passive
	5000+	1st-2nd highest in the team
	80%+	The higher, the less score variance
	200%+	The higher, the better
	0%	At T6, Weakness Hit Chance reaches 100%
	-	5th (lowest) in the team
	4500+	1st-2nd highest in the team
	80%+	The higher, the less score variance
	200%+	The higher, the better
	20%	81% with Biscuit/Rachel buffs
	-	4th in the team

For attackers, it's recommended to lower Speed so they can receive buffs for longer, but making Ryan 5th will throw off the CD Reduction timing, so set Ryan to 4th and Sunran to 5th.

Tips!

If your attackers keep getting defeated, raising their DEF or HP with Potential or equipment is also an option.

Recommended Equipment & Rings

Hero	Equipment	Ring (Refine)
Biscuit
Sieg
Rachel
Sunran
Ryan

Biscuit is a Spellweaver, so a status ailment ring is recommended for her equipment. The others are recommended to use Avenger gear, but that makes them easier to take down, so at the very least, Sieg should equip a Ring of Authority. Depending on the situation, a Ring of Authority may also be an option for other characters.

Recommended Pets

Ideal	Alternate	Alternate	Low Rarity
Windy	Eirin	Igris	Sherry

For pets, Windy, who can inflict Boss Vulnerability, is the most recommended. If you don't have her, use Eirin or the collab Rare pet Igris as a substitute.

Alternate Characters

Main Pick	Alternate	Notes
	Yui	Early-game Burn Immunity
	Evan	Early-game Stun Immunity
	Feng Yan	Early-game 3-target Physical Attacker
	Taka	Alternate 3-target Physical Attacker

If Taka is more developed than Sunran, swapping her in may increase your score in some cases. If Ryan or Sieg aren't developed, it's fine to swap in Yui or Evan, who you'd use for Power Up Dungeons or raids.

Sunran's Demon Face stacks +3 times as each WAVE progresses, so you can clear WAVE 2 using the skill's automatic activation at 6 stacks. Sunran's Awakening Skill targets all enemies and doesn't deal much damage, so avoid using it.

Tips!	This skill order focuses on keeping Ryan alive, since he acts fourth in the turn order and has no Revive skill.
