01 · SETUP

Starting setup

Availability depends on your unlocks

Recommended character

White Rabbit

Special attack damage +12% and maximum MP +8 strengthen special attacks. Evasion decreases by 15, so do not rely on evasion rolls to survive.

Fruit skewer 6 total

  • Watermelon(Lake)×3
  • Peanut(Sturdy)×3

Wishing fountain Fountain usage 8 of 9

  • Brass Mirror FragmentCapacity 5
  • Endoditte’s PaperweightCapacity 3
Why this choice
Use Brass Mirror Fragment to reduce special-attack MP costs and Endoditte’s Paperweight to increase maximum MP and MP regeneration. With one item from each of two different categories, no bond is active at the start. This uses 8/9 Wishing Fountain capacity and requires the items to be unlocked.

Talents 50 points

  • Willpower20
  • Wisdom20
  • Wrath10
Why this choice
Willpower 20 increases fountain capacity to 9 and provides 25 maximum MP. Wisdom 20 improves MP regeneration and absorption and provides 1 free reroll for each item reward. Wrath 10 increases critical chance, critical damage, and damage against bosses.

Recommended miracle

Angler

  • Damage of MP-consuming abilities +15%
  • Maximum MP +15
  • Gain 1 Lake artifact (selected from unlocked, eligible candidates)
Why this choice

  3. Maximum MP and physical damage

03 · HOW TO PLAY

Playing this build

1Early preparation

With Colossal Crossbow, use the 10 MP enhanced arrow only when needed and conserve resources with normal firing.

2Upgrades and transition

Use the wide, powerful enhanced arrows of Enhanced Special Bolts. After obtaining Rapid-Fire Device, first prepare enough MP to cast repeatedly within 2 seconds.

3Combat loop

  1. Secure MP before the boss or enemy group becomes exposed.
  2. Fire enhanced arrows at intervals of 2 seconds or less to build the consecutive bonus.
  3. Stop rapid firing if you need to evade or run low on MP. Mix in normal firing to restore MP and find the next attack opportunity.

Boss fights

Concentrate special attacks during recovery windows with little movement. Break the chain without hesitation if maintaining the bonus would mean taking a hit.

Without the core items

Without Stone Spindle Whorl, secure MP with Endoditte’s Paperweight and Water Bag. Supplement special attack damage with Shield Training Manual or Silver Plate.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • The chain requires intervals within 2 seconds; the first shot after a long pause does not receive the maximum bonus.
  • Do not count Academy's reduced Grimoire MP costs as a reduction to crossbow special attack costs.

Needs further verification

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