Recommended miracle

Angler

Why this choice
Increase the damage of MP-consuming abilities by 15% and maximum MP by 15 to support Whirlwind. Also gain 1 Lake 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. Special attack damage and reduced MP consumption
  2. MP regeneration and maximum MP
  3. Weapon critical chance and critical damage
  4. Core artifact levels and defensive stats

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 → Hypersensitivity → Negligence. Intermediate weapon effect: Special Attack: Whirlwind gains 20% damage and 50% charge speed. After the final evolution, Whirlwind charges instantly, making it easier to use during brief openings. Special attack damage increases by 15%, but its animation speed decreases by 15%. Check both your remaining MP and whether you will have time to dodge after the attack.

3Combat loop

  1. Use Whirlwind once immediately after the enemy's attack ends.
  2. Once the animation ends, move to avoid the next attack.
  3. Use it again at the next opening only if you have enough MP.

Boss fights

You can use Whirlwind during an opening without waiting for a charge. The attack animation still takes time, so leave enough time after it ends to dodge the boss's next attack.

Without the core items

Without Bronze Mirror Fragment, replenish MP with Endoditte’s Paperweight and White Branch, and leave longer intervals between uses.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • Charge time and special attack animation speed are different values.
  • Whirlwind cannot be used without enough MP, so check your remaining MP before repeated uses.

Needs further verification

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