  • Gain 1 Guardian artifact (selected from unlocked, eligible candidates)
Why this choice
Add 15 defense for melee survivability and gain 1 Guardian artifact to help form combos. 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. Defense
  2. Normal attack damage and HP absorption
  3. MP regeneration and maximum MP
  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.

8Combo target
  • Cloth Armor

    Increase defense to reduce incoming damage in melee combat.

  • Beast's Heart

    Increase defense and all damage amplification to support both offense and survival. Also gain additional luck.

  • Pan Lid

    Improve MP regeneration and evasion. Landing a physical critical hit also grants the Endure buff, which increases defense.

Bond choices and conditions
Increase defense to support Reassemble's extra damage and survivability. You do not need every recommended item. Reach the target combo with other items in the same category and placement bonuses.
Support

Sturdy

6Combo target
  • Warrior Seal

    Increase physical damage and attack speed to strengthen weapon attacks.

  • Begonia Sachet

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

  • Amulet of Courage

    Gain weapon damage and HP absorption to support damage and recovery during continuous attacks.

Bond choices and conditions

Support

Lake

3Combo target
  • Endoditte’s Paperweight

    Increase both maximum MP and MP regeneration to sustain abilities that consume MP.

  • White Branch

    Increase MP regeneration to help use MP-consuming abilities again.

Bond choices and conditions
Secure enough MP to use Reassemble again. 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

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 → Bone Gearblade → Creaking Spine. Intermediate weapon effect: Special Attack changes to Special Attack: Reassemble. Attack Speed gradually increases on Normal Attack. (Up to 35%, resets when you stop attacking) After the final evolution: The enlarged Reassemble attack adds bonus damage equal to 15 plus 50% of armor. Raise armor for both added damage and survival, and maintain normal attacks during safe windows.

3Combat loop

  1. Secure MP to activate Reassemble and a safe approach route.
  2. Keep using normal attacks with the extended blade during Reassemble.
  3. When an enemy prepares a major counterattack, abandon accumulated attack speed and evade.

Boss fights

Activate Reassemble at the start of an opening after a boss attack and keep attacking from long range. Check MP and patterns before reengaging immediately after it ends.

Without the core items

Without Beast's Heart, build armor with Cloth Armor and Pan Lid, and sustain normal attacks with Warrior Seal.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • Even with more armor, stopping attacks may reset Bone Gearblade's accumulated attack speed.
  • Lizard Plate Armor penalizes movement and attack speed, so avoid excessive defensive investment.

Needs further verification

  • Current translations give both 25 and 30 for Reassemble's MP cost, so no specific value is stated.
