01 · SETUP

Starting setup

Availability depends on your unlocks

Recommended character

Wizard Bunny

Use 15% ice damage amplification and the starting Ice Bolt spellbook. Physical damage amplification decreases by 20%, so do not rely solely on physical hits. The penalty to the physical damage portion remains after evolution.

Fruit skewer 6 total

  • Wind Spirit Fruit(Wind Song)×2
  • Peanut(Sturdy)×1

Wishing fountain Fountain usage 8 of 9

  • Charm of IntelligenceCapacity 3
  • Sword Training ManualCapacity 5
Why this choice
Prepare Charm of Intelligence and Sword Training Manual at the Wishing Fountain. This uses 8/9 capacity, and the items must be unlocked first. Then collect items in the same categories to complete the target combos.

Talents 50 points

  • Willpower20
  • Swiftness20
  • Wrath10
Why this choice
Willpower 20 adds 15 maximum HP and 25 maximum MP and provides 9 Wishing Fountain capacity. Swiftness 20 adds 20% attack speed, 8 evasion, and 1 dash charge. It also increases dash recovery speed and final weapon damage. At level 20, dash invincibility lasts 0.1 seconds longer, with an additional final weapon damage bonus. Wrath 10 adds 10% critical chance and 20% critical damage. Damage dealt to bosses and minibosses also increases by 10%. Uses 50 points in total.

Recommended miracle

Snowfield Sentinel

  • Ice damage +9
  • Movement speed +10%
  • Gain 1 Glacier artifact (selected from unlocked, eligible candidates)
Why this choice
Add 9 ice damage and 10% movement speed to support ice attacks and spacing. Also gain 1 Glacier 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. Ice damage
  2. Attack speed and melee attack range
  3. Normal attack damage
  4. Core artifact levels and defensive stats

02 · SYNERGY

Target bonds and core items

Prioritize the items below when available. Reaching the target combo requires additional items of the same category and their placement; leveling an item alone does not increase the combo count.

Primary

Glacier

8Combo target
  • Charm of Intelligence

    Increase ice damage to strengthen ice attacks and artifacts that scale with ice damage.

  • Fluffy Fur Gloves

    Increase the ice damage taken by enemies with Frostbite. Apply Frostbite first to benefit from the effect.

  • Feet of the Ice Gull

    Applying Frostbite grants Frozen Touch, increasing ice damage. Keep applying Frostbite to maintain the buff.

Bond choices and conditions
Increase ice damage to strengthen the cold added to weapon hits. You do not need every recommended item. Reach the target combo with other items in the same category and placement bonuses.
Support

Wind Song

6Combo target
  • Sword Training Manual

    Increase attack speed to chain weapon attacks more quickly.

  • Wanderer's Necklace

    Increase attack speed and your highest elemental damage. Support your main element while repeating attacks.

  • Wind Sheet Music

    Expand melee attack range to make attacking from a distance easier. This item does not increase attack speed.

Bond choices and conditions
Support attack speed and melee range to continue combos from a safe distance. You do not need every recommended item. Reach the target combo with other items in the same category and placement bonuses.
Support

Sturdy

4Combo target
  • Begonia Sachet

    Increase normal attack damage. Use it with weapon effects that benefit from normal attack bonuses.

  • Eternal Winter

    Normal attack hits have a chance to deal an additional hit based on physical and ice damage. This hit also counts as normal attack damage.

Bond choices and conditions
Combine normal-attack damage with Eternal Winter's additional hits. You do not need every recommended item. Reach the target combo with other items in the same category and placement bonuses.

03 · HOW TO PLAY

Playing this build

1Early preparation

While using Steel Greatsword, combine the starting Ice Bolt grimoire with weapon attacks. Physical damage amplification is reduced by 20%, so use magic to supplement your damage. Charge Whirlwind from a safe position before enemies close in. Use the items prepared at the Wishing Fountain; the final weapon's unique effect becomes available after evolution.

2Upgrades and transition

Steel Greatsword → Frostbound Greatsword → Eternal Frost Greatsword. Intermediate weapon effect: When performing a Weapon Attack, deal additional damage to the target equal to 30% of Cold Damage. After the final evolution: The extra ice damage on weapon attacks increases to 55% of your ice elemental damage. Use the wider reach and faster basic chain to keep your distance while repeatedly dealing extra ice damage.

3Combat loop

  1. Land wide normal-attack chains from outside enemy reach.
  2. Keep dealing extra ice damage to enemies with Frostbite stacks.
  3. If enemies close in, move and reestablish the edge of your range.

Boss fights

Use the fast chain without pressing too close. The character's physical damage reduction remains after evolution, so use both extra ice damage and the starting spell.

Without the core items

Without Eternal Winter, use Charm of Intelligence and Sword Training Manual to strengthen the weapon's own extra cold damage.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • 55% is the coefficient for extra ice damage, not a multiplier for the weapon's entire damage.
  • Do not extend the normal attack range and combo improvements to all aspects of special attacks.

Needs further verification

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