3 things to understand first
- Focus on Kira and leave Matthias to the NPCs.
- Do not equip Defense s on targets of unopposed attacks left to assistance.
- After defeating Kira, keep checking s and tattoos; avoid unnecessary attacks.
GUIDEKeys to the fight
Turn numbers indicate a typical sequence. HP loss and Stagger can change the order, so also check the names of the skills the enemy is using.
Find a response based on how you lost
- Allies die when attacking Matthias
- His ordinary and its Great Brother tattoo reuse are dangerous. Have Sinners attack only Kira and leave damage against Matthias to the NPCs.
- Assistance fails to activate and Sinners take heavy damage
- Ezra and Vespa's intercepts unopposed attacks against allies with no Defense s equipped. Do not clash with an attack left to them or equip Defense s in any other slot of its target. Also check that the NPC has equipped.
- Kira's opening attack consumes an Ampule
- Losing to “” is especially dangerous. Win the opening clash with a strong regular skill or . Moses's makes clashes easier from Turn 2 onward.
Before deployment
Bring healing to protect the three required Sinners and the NPCs
- Recommended Lv. 60. Level Yi Sang, Don Quixote, and Hong Lu. Each has two slots, so divide attacks against Kira and healing duties.
- Moses, Ezra, and Vespa fight alongside you. You lose if any NPC dies, so do not spend all shared Ampules on Sinners.
- Kira is vulnerable to Pierce. Consider affinity, but also save a way to beat the opening “”.
Opening
Defeat Kira without attacking Matthias
- All three Sinners focus on Kira. Spare attacks against Matthias trigger his ordinary ; use spare actions for healing or necessary defense instead.
- Stop the opening “” with a strong skill. Watch for reuse at 4 or more and for additional damage.
- applies 3 to Kira on Turn 2. Check the effect and remaining duration, then use improved clash predictions to and defeat her.
When Matthias targets a Sinner
Maintain the conditions for NPC assistance
- Check that Ezra or Vespa has equipped. Do not assign a Sinner to clash with an attack left to them; keep it unopposed.
- Do not equip Defense s on the targeted Sinner. Defense in another slot of the same Sinner also breaks the condition, so use attacks against Kira or healing instead.
- Even if a Sinner is predicted to win, taking over the clash changes assistance and management. Generally leave it to the NPCs and focus on Kira.
Automatic follow-up attacks
Do not count event attacks as extra selectable skills
- Don Quixote performs an automatic follow-up on Turn 2, and Yi Sang on Turn 5. These are separate from skills selected from your hand; there is no need to prepare resources as for an ordinary use.
- Don Quixote's automatic follow-up does not trigger Matthias's . This does not mean regular attacks are safe too.
After Kira is incapacitated
Wait for the NPCs to finish without adding Counters
- Once Kira is defeated, everyone does not need to attack Matthias. Hold attacks unless he has no and can be attacked safely. Having no tattoos does not remove the itself.
- On turns when NPCs use , do not cancel their assistance by equipping Defense s. Check targets and available assistance, then choose healing or withholding attacks as appropriate.
- The battle ends through an event below a certain HP threshold. ing Moses for three turns in 9-44 is not this battle's ending condition.
NOTESUnique effects and cautions
Easy-to-miss details
- Matthias uses an ordinary . Avoid triggering it by withholding attacks; it cannot be stopped through a clash win.
- Additional attacks against Matthias add tattoos based on all skills that hit, including NPC skills. This does not mean three Sinner attacks are safe.
- Do not equip Defense s on targets left to . Check support conditions every turn even after Kira is defeated.
- s, support, and ending conditions differ from the 9-44 rematch. Do not apply its final escort procedure here.
When taking lethal damage while another ally is alive, clear and fully restore HP. Every ally's remaining Ampule count decreases by 1 simultaneously.
Check the remaining count shared by NPCs and Sinners on screen. These are not separate revival counts per character.
Ezra and Vespa intercept unopposed attacks against allies with no Defense s equipped.
Do not assign clashes to attacks left to assistance, or equip Defense s on the targeted Sinner. Check whether the NPC is using assistance that turn too.
Maximum 10. Per stack: +1, −2, damage +5%. At maximum, damage taken +20%. Consumed by specific skills.
Careless Sinner attacks against Matthias trigger more dangerous skills.
Maximum 2; expires at Turn End. Blunt and Envy damage +10%. Enables additional effects on s and other skills.
While active, hold back attacks against Matthias and leave him to the NPCs.
Maximum 3; expires at Turn End. Blunt and Envy damage +5%. Enables effects such as reuse.
While focusing on Kira, maintain HP on Sinners exposed to s.
Maximum 10. Base Power +1 per 2 stacks; Slash and Blunt damage +5% per stack. Lose 1 after taking damage from skills twice.
Do not add Sinner attacks solely to lower this value; consider the resulting s first.
Maximum 10. Base Power +1 per 2 stacks; Slash and Blunt damage +8% per stack. Lose 1 after taking damage from skills twice.
Keep winning clashes and focusing on Kira to prevent her reuse condition from being met.
Activates at 3 or more . s that inflict also inflict .
Win clashes to stop the attacks and prepare healing for both and damage.
When either Middle enemy lands a skill hit, heal 7 SP once per skill.
Hits also help maintain enemy SP. Sinners should win against Kira while the NPCs handle Matthias.
Moses's support against Kira: 3 from Turn 2 for five turns.
Do not permanently subtract it from enemy base values. Check the active effect and its remaining duration.
PARTYRecommended teams and preparation
What to prepare first
- Recommended Lv. 60. Yi Sang, Don Quixote, and Hong Lu are the three required Sinners. Prepare a strong opening clash and HP/SP recovery.
- Pierce damage is effective against Kira. Maintain NPC assistance rather than forcing extra damage against the Nursefather.
Clashes and focused damage against Kira
Reduce enemy actions while the NPCs handle the Nursefather.
HP and SP recovery
Recover damage from s and ordinary s.
Maintain NPC assistance
Preserve the conditions: an unopposed attack and no Defense s equipped on its target.
One ally can fill several roles. First choose a main fighter who can win Clashes, then assign responsibilities for dangerous attacks and special mechanics.
STATUSBasic stats
Stats for 9-38. Deployment limit: 3 Sinners. Only Yi Sang, Don Quixote, and Hong Lu deploy; each has two skill slots. Enemy tables show base values, with NPC debuffs handled separately. Matthias triggers the ending event below a certain HP threshold, whose exact value is unconfirmed. Do not apply 9-44's final escort conditions or 701 HP threshold here. Check the initial shared Ampule count on screen.
