01 · SETUP

Starting setup

Availability depends on your unlocks

Recommended character

Frog

Use lightning damage amplification +15% and the starting Lightning Arrow spell. Physical damage amplification -20% reduces early weapon damage, so compensate with lightning spells.

  • Plum(Storm Cloud)×3
  • Pineapple(Magitech)×3

Wishing fountain Fountain usage 9 of 9

  • Lightning StoneCapacity 5
  • Sapote FruitCapacity 4
Why this choice
Use Lightning Stone and Sapote Fruit to activate the tier-2 Storm Cloud bond. Lightning Stone strengthens Storm Cloud damage, while Sapote Fruit improves Storm Cloud capacity and MP regeneration. These unlocked items use all 9 points of Wishing Fountain capacity.

Talents 50 points

  • Willpower20
  • Ingenuity20
  • Swiftness10
Why this choice
Willpower 20 increases fountain capacity to 9 and provides 25 maximum MP. Ingenuity 20 expands the bag and available choices, and increases final damage by 7% per active bond category. Swiftness 10 improves attack speed, dash charges, and dash recovery.

03 · HOW TO PLAY

Playing this build

1Early preparation

At the base Colossal Crossbow stage, compensate for reduced physical damage with Lightning Arrow and Storm Cloud. Before Cloud Gatherer, regular arrows cannot charge Storm Cloud.

2Upgrades and transition

Obtain lightning arrows through Unstable Lightning Mark. After Cloud Gatherer, hitting with those lightning arrows grants Storm Cloud charge.

3Combat loop

  1. Confirm Storm Cloud is active, then fire normal shots so lightning arrows hit enemies.
  2. Spend your magazine while staying close enough for cloud strikes to reach enemies.
  3. After reloading and evading, land hits again to reduce the time the cloud is empty.

Boss fights

Keep landing lightning arrows on the boss while avoiding hits. If cloud charge is full, prioritize actual cloud damage over adding more charge gain.

Without the core items

If you cannot bring Lightning Stone, activate the tier 2 Storm Cloud bond with Sapote Fruit and Stone Flower first. The two items cost 7 fountain capacity in total, fitting within the capacity of 9 from Willpower 20.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • If the Storm Cloud bond is inactive, the charge effect alone will not create a cloud.
  • Do not assume the starting Lightning Arrow Grimoire and the weapon's lightning arrows share the same charging trigger.

Needs further verification

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