Tips for Clearing Castle Rush Kris (Sunday)
Death Immunity is a Must
The enemy inflicts Death. Without any countermeasures you'll be at a serious disadvantage, so make sure to include a hero with Death Immunity in your team. Xiao is recommended, as she can generate Barriers, heal HP, and boost single-target attack damage.
Use Single-Target Attackers
Every enemy in Hell Castle applies Quintuple-Target Attack Resistance against 5-target attack skills, and attacking either of the two enemies besides Kris shortens Kris's skill cooldown, so attack with single-target skills instead. Shane and Pascal are especially recommended.
Clear Rounds 1-2 Quickly First
Castle Rush consists of 3 rounds, with the boss Kris appearing in Round 3. Since you need to raise your score as much as possible within 70 turns, aim for an early clear in Rounds 1-2 using 3-target attacks such as Biscuit, Miho, and Heavenia.
Use Focus Target or Boost Weakness Hit Chance
When you reach Round 3, apply Focus Target on Kris with Asura so you can attack her directly, or raise your attackers' Weakness Hit Chance with Biscuit.
If you're using Biscuit, it's better to raise the Weakness Hit Chance of your non-attacker heroes through equipment instead.
Boost Damage with Buffs and Debuffs
Next, boost your attackers' damage with Buffs and Debuffs. It's recommended to apply the Buffs/Debuffs with the longest duration first.
Whittle Down Enemy HP with Attackers
Once your setup is ready, use your backline attackers to whittle down enemy HP. Prioritize the skills of Shane and Pascal (with Skill 1 upgraded), and it's better if you're also mindful of increasing your skill cycle rate.
Manage HP with Barriers and Healing
To raise your score, you'll want to prioritize attacking, but it's all for nothing if your heroes get defeated. Make sure to manage HP properly with Barrier and healing skills so no one goes down.
Upgrade and Transcend Your Heroes
Raising your score requires progressing through Upgrades, Transcend, and Ultimate Enhancements. In particular, prioritizing Ultimate Enhancement and Skill Enhancement for your attackers is recommended, as it makes it much easier to boost your score significantly.
Efficient Ways to Train Your Heroes
Recommended Team Examples
Intermediate-to-Advanced Shane Team
Team Comp Formation: Defense
Buff/Debuff
Barrier
Heal
Buff/Debuff
Heal
Debuff
This is an example of a physical-type team with Shane as the main attacker. Her passive and active skills let you stack Defense Reduction and Physical Vulnerability, and by also equipping a Bleed accessory, you can boost your score further through the bonus damage from Xiao's Bleed effect.

| 200%~ | The higher, the better | |
| 40%~50% | 100% with Biscuit's buff | |

| 250%~ | The higher, the better | |
| 40%~50% | 100% with Biscuit's buff | |
| - | Recommended to be 5th in the team |
Since you'll need to target Kris, it's ideal for everyone's Weakness Hit Chance — including from buffs — to be close to 100%.
If Fai's Transcendence count is low, Rare Heroes can easily surpass her in Attack, so make adjustments using Equipment, Dedicated Equipment, and Potential.
| Tips! | To keep the buff effect active for as long as possible, it's recommended to adjust Speed so that Fai acts 4th and Shane acts 5th. |
|---|
Best Equipment & Rings
Best Pets
| Ideal | Alternative | Alternative | Low Rarity |
|---|---|---|---|
 Windy |  Eirin |  Igris |  Sherry |
For pets, Windy, who can apply Boss Vulnerability, is the most recommended. If you don't have her, use Eirin or Igris, a Rare Collaboration pet, as substitutes.
Alternative Heroes
| Main Pick | Alternative Hero | Notes |
|---|---|---|
|  Leo | Death Immunity option (not recommended) |
|  Rachel | Substitute for Physical Vulnerability |
|  Lina | Substitute for Defense Reduction and Healing |
|  Bai Long | Substitute for a Single-Target Physical DPS |
If you don't have or haven't upgraded the recommended heroes, using the above as substitutes is a viable option. To make the most of Shane's Damage Boost that scales with the number of debuffs, prioritize Support heroes that apply debuffs.
Skill Usage Order
By using Biscuit's skill on the 2nd action of Wave 3, you can use Shane's and Fai's skills while keeping the skill effect active. If your heroes start getting knocked out late in the battle, changing the timing of Xiao's Barrier skill is also an option.
Pascal Team for Intermediate to Advanced Players
Team Composition | Formation: Defense
Buff/Debuff
Barrier
Heal
Buff/Debuff
Barrier
This is an example magic team with Pascal as the main attacker. In the current meta, Shane teams tend to score higher, but if your magic-type heroes are more developed, this team can sometimes score higher instead.

| 300%+ | The Higher, the Better | |
| 40%-50% | 100% with Biscuit's Buff | |
| - | Recommended to Rank 5th in the Team |
Since you need to target Castle Rush Kris, it's ideal that everyone's Weakness Hit Chance (including buffs) is close to 100%. To keep receiving buff effects for as long as possible, it's recommended to adjust Speed so that Xiao Qiao ranks 4th and Pascal ranks 5th.
Recommended Equipment & Rings
Recommended Pet
| Ideal | Alternative | Alternative | Low Rarity |
|---|---|---|---|
| Windy |  Yeonji | Igris |  Note |
For pets, Windy, who can inflict Boss Vulnerability, is the most recommended. If you don't have it, substitute with Yeonji or the collab rare pet Igris.
Alternate Heroes
| Main Pick | Alternate Hero | Notes |
|---|---|---|
| Leo | Death Immunity Option (Not Recommended) |
| Lina | Alternative for Buff/Debuff |
|  Daisy | Alternative for Buff/Barrier |
If you don't have or haven't raised the recommended heroes, it's fine to use the heroes above as substitutes, but your score will likely drop. If you swap out Xiao for Leo, it's better to also bring in someone with a Defense Reduction skill, like Lina.
Skill Usage Order
Weave in Biscuit/Xiao/Xiao Qiao's buffs and debuffs as needed, and use Pascal's skills as efficiently as possible. The above assumes Pascal is at Transcendence 2 or higher with Skill 1's cooldown at 40 seconds; if below Transcendence 2, the order may change.
Early Game Team
| Front | Front | Front | Back | Back |
|---|---|---|---|---|
| Xiao Death Immunity Buff Heal | Asura Focus Target | Yui Healer | Yuri DPS | Xiao Qiao DPS Buff/Debuff |
