01 · SETUP

Starting setup

Availability depends on your unlocks

Recommended character

Armored Bunny

Defense +10 strengthens both normal attack damage and survival. Maximum HP decreases by 15, so secure the HP increase from Willpower and a way to recover health.

Fruit skewer 6 total

  • Guardian Fruit(Guardian)×3
  • Peanut(Sturdy)×2
  • Wind Spirit Fruit(Wind Song)×1

Wishing fountain Fountain usage 9 of 9

  • Lizard Plate ArmorCapacity 5
  • Warrior SealCapacity 4
Why this choice
Use Lizard Plate Armor to increase defense and Warrior Seal to supplement physical damage and attack speed. Account for the plate armor's speed penalty and choose safe opportunities to attack. Fountain usage is 9/9, and the items must be unlocked to bring them in.

Talents 50 points

  • Willpower20
  • Endure20
  • Swiftness10
Why this choice
Willpower 20 provides 9 fountain capacity. Endure 20 provides 20 defense and one revival for survival; Swiftness 10 supports offense and escape through attack speed, dash recovery, and final weapon damage.

Recommended miracle

Attendant

  • Defense +15
  • Gain 1 Guardian artifact (selected from unlocked, eligible candidates)
Why this choice
Add 15 defense to improve survival and normal attack damage that scales with defense.

Stat priorities

  2. Physical damage
  3. Normal attack damage
  4. Attack speed

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

Guardian

8Combo target
  • Cloth Armor

    Gain defense without detrimental side effects.

  • Lizard Plate Armor

    Greatly increase defense. Movement speed, attack speed, and spellbook acceleration decrease, so compensate for missing stats with other equipment.

  • Beast's Heart

    Increase both defense and all damage amplification.

Bond choices and conditions
Raise Defense to scale your main attack and improve survival.
Support

Sturdy

4Combo target
  • Warrior Seal

    Improve physical damage and attack speed.

  • Begonia Sachet

    Increase normal attack damage.

  • Silver Plate

    Strengthen normal attacks and special attacks when needed.

Bond choices and conditions
Avoid stacking Defense alone while neglecting base physical damage and basic attack bonuses.
Support

Wind Song

4Combo target
  • Sword Training Manual

    Directly increase attack speed.

  • Golden Cloak

    Secure dash charges and attack speed.

Bond choices and conditions
Offset the attack speed loss from heavy defensive equipment.

03 · HOW TO PLAY

Playing this build

1Early preparation

At the Blade stage, survive with defensive equipment; defense does not convert to normal attack damage yet. Block dangerous attacks with sheathed defense.

2Upgrades and transition

From Armor-Bender onward, every 2 defense increases normal attack damage by 1%. After evolving into Breakplate Blade, gain Hardening every 0.8 seconds while drawn; sheathing at maximum stacks transforms normal attacks.

3Combat loop

  1. Keep moving and using normal attacks while drawn to stack Hardening to maximum.
  2. When Hardening reaches maximum, sheathe at a safe moment to enhance normal attacks.
  3. After using the transformed normal attack, build Hardening again while drawn. Prioritize dashing or defense against dangerous patterns.

Boss fights

Stay drawn to build Hardening while avoiding the boss's patterns. When Hardening reaches maximum, sheathe and use the transformed normal attack during the boss's opening.

Without the core items

Without plate armor, substitute Cloth Armor or Broken Mirror for defense. If attack speed becomes too low, secure Sword Training Manual instead of adding more defensive equipment.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • Hardening builds while drawn, and sheathing at maximum stacks transforms normal attacks. Remaining drawn continuously misses this enhanced attack.
  • The damage bonus proportional to defense applies to normal attacks. Special attacks and magic do not receive the same bonus.
  • Be careful: the Berserker miracle's 15 defense reduction lowers both survival and normal attack damage.

Needs further verification

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