01 · SETUP

Starting setup

Recommended character

Otter

Critical chance increases by 9%, strengthening weapon attacks. Movement speed decreases by 8%, so establish a safe attacking position in advance.

Fruit skewer 6 total

Wishing fountain Fountain usage 9 of 9

  • Crown of HumilityCapacity 6
  • Begonia SachetCapacity 3
Why this choice
Prepare Crown of Humility and Begonia Sachet at the Wishing Fountain. This uses 9/9 capacity, and the items must be unlocked first. Then collect items in the same categories to complete the target combos.

Talents 50 points

  • Wrath20
  • Swiftness10
Why this choice
Willpower 20 adds 15 maximum HP and 25 maximum MP and provides 9 Wishing Fountain capacity. Wrath 20 adds 20% critical chance and 20% critical damage. Damage dealt to bosses and minibosses also increases by 10%. Also gain 20 armor penetration. Swiftness 10 adds 10% attack speed, 8 evasion, and 1 dash charge. It also increases dash recovery speed and final weapon damage. Uses 50 points in total.

Recommended miracle

Hunter

  • Critical damage +40%
  • Gain 1 Precision artifact (selected from unlocked, eligible candidates)
Why this choice
Increase critical damage by 40% to strengthen damage when a critical hit occurs. Also gain 1 Precision artifact. The granted item is selected from candidates that meet the unlock and eligibility requirements, so a particular core item is not guaranteed.

Stat priorities

  1. Final chain-hit damage and normal attack damage
  2. Final chain-hit critical chance and critical damage
  3. Attack speed
  4. Core artifact levels and defensive stats

03 · HOW TO PLAY

Playing this build

1Early preparation

With the Steel Greatsword, use normal attack chains at the edge of your reach and Whirlwind charged safely in advance. Look for openings after enemy attacks so you do not get hit while charging. Use the items prepared at the Wishing Fountain; the final weapon's unique effect becomes available after evolution.

2Upgrades and transition

Steel Greatsword → Swarming Shadow → Swift Regret. Intermediate weapon effect: Special Attack: Whirlwind charge time increases by 100%, but Normal Attack Damage increases by 20%. After the final evolution: Repeat the final normal-attack swing twice more for up to three finishing swings. Raise their damage and critical chance, and land the extra swings only when you can finish before the enemy retaliates.

3Combat loop

  1. Start the normal-attack chain at a safe distance.
  2. During long openings, continue through the extra finishing swings.
  3. During short openings, stop the chain and wait for the next opportunity.

Boss fights

Once the boss starts moving, do not force the two extra finishing swings. Focus on long knockdowns and openings after attacks.

Without the core items

Without Crown of Humility, improve the final swings' critical chance and base damage with Golden Crown of Arrogance and Begonia Sachet.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • Extra finishing swings do not mean every normal attack is tripled.
  • Do not keep investing in the intermediate weapon's slowly charged special attack.

Needs further verification

No specific unresolved issues are listed. This does not mean performance has been verified in actual play.
