Seven Knights Re:BIRTH: Dellons Castle Rush Team and Stat Tuning

To direct Biscuit's offensive buffs onto Ryan and Rachel during Castle Rush against Dellons, you must tune your party's Attack stats before battle. Ryan must have the highest Attack on the team, Rachel must have the second highest, and Eileene must stay below Rachel. If Rachel's Attack is too low to surpass Eileene naturally, equip Eileene with a damage reduction gear piece to suppress her offensive stat.

Attack Stat Hierarchy and Biscuit's Buff Targeting

Biscuit targets the allies with the highest Attack values when applying offensive enhancements. If support heroes carry higher Attack totals than your damage dealers, Biscuit wastes buffs on the wrong units, lowering your team's damage against Dellons.

Organize your party's gear and growth so that the Attack stats strictly follow this order:

Hero	Attack Target Hierarchy	Team Function	Equipment Focus
Ryan	Highest Attack	Primary single-target damage dealer	Attack, Critical Rate, Critical Damage
Rachel	Second-highest Attack	Secondary damage dealer, defense and damage debuffs	Attack, Speed, Debuff Accuracy
Eileene	Below Rachel	Passive physical attack buffer, secondary damage	Damage Reduction, HP, Defense
Biscuit	Lowest offensive priority	Dedicated offensive buffer	Speed, Skill Cooldown, Survivability

Ryan serves as the primary offensive carry, while Rachel applies defense reduction and damage output reduction to weaken Dellons. Biscuit's buffs must land on both to ensure Ryan maximizes damage during vulnerability windows and Rachel contributes steady secondary output.

Why Eileene Requires Damage Reduction Gear

Eileene provides a strong passive Attack boost to the party, but her base stats and offensive scaling often push her Attack higher than Rachel's. When Eileene's Attack exceeds Rachel's, Biscuit buffs Eileene instead of Rachel, breaking your offensive setup.

To fix this stat conflict, replace an offensive armor or accessory slot on Eileene with a dedicated damage reduction item:

Lowers Offensive Growth: Removing an Attack piece from Eileene keeps her flat Attack total safely under Rachel's value without disabling her passive team buff.
Improves Frontline Durability: Dellons hits harder as the battle extends. Adding damage reduction helps Eileene absorb incoming strikes and stay alive deeper into the fight.

While this adjustment reduces Eileene's personal damage output, preserving Biscuit's buffs on Rachel yields higher overall team damage.

Skill Order and Turn Sequence

Once your stats are aligned, execute the encounter with the following rotation:

Activate Biscuit's buffs: Biscuit should act early to apply targeted offensive enhancements to Ryan and Rachel.
Apply Rachel's debuffs: Cast Rachel's defense-reduction and damage-reduction skills immediately after receiving Biscuit's buffs to weaken Dellons' damage and armor.
Attack with Ryan: Trigger Ryan's high-damage single-target skills while Dellons is debuffed and Ryan has active offensive buffs.
Reapply debuffs if cleared: If Dellons strips buffs or reaches a new phase, re-establish Rachel's debuffs before spending Ryan's main cooldowns.

Stat Verification Checklist

Before starting a Dellons Castle Rush run, confirm these details on your team management screen:

Open the hero stat sheets and verify that raw Attack values follow the sequence: Ryan > Rachel > Eileene.
Check Eileene's equipment slots to confirm she has at least one damage reduction piece equipped.
Confirm Rachel has adequate speed or accuracy so her debuffs apply reliably before Ryan attacks.
