Prized Isshin Blade

Temporary quest-form sword with a periodic area hit and self-healing effect.

Introduced in v2.8

Prized Isshin Blade is a temporary four-star sword form with 42.401 Base ATK and an ATK secondary stat. Consider it during the story encounter where the form is available if you want its attack-triggered area damage and HP restoration. A Normal, Charged, or Plunging Attack that hits an opponent releases an Accursed Spirit, but the effect can trigger only once every 8 seconds and the wielder’s damage is decreased by 50%.

Prized Isshin Blade GUIDE

Understand Prized Isshin Blade

Useful when…

  • Using the periodic area hit and self-healing effect during the story encounter where this temporary form is available.
  • Distinguishing this healing form from the related form whose listed effect omits HP restoration.

What triggers the effect?

The wielder must hit an opponent with a Normal, Charged, or Plunging Attack. The resulting Accursed Spirit deals area damage equal to 180% of ATK and restores HP equal to 100% of ATK. The effect can trigger once every 8 seconds, so the listed damage and healing are periodic rather than benefits on every attack.

What limits its damage role?

The weapon decreases the wielder’s damage by 50%. Its triggered area hit does not cancel that stated penalty. The healing can support the wielder’s survival in the encounter, but it is tied to the same limited trigger and does not provide continuous recovery.

What should you know about investment?

This is a temporary story-quest form with 42.401 Base ATK and an ATK secondary stat. Quest weapon forms do not inherit ordinary leveling, so standard weapon-level investment is not the way to improve this form. Its listed effect also requires a qualifying attack to hit an opponent before it can activate.

How does the related form differ?

Another Prized Isshin Blade form shares the listed trigger, 180% ATK area damage, 8-second limit, and 50% damage decrease, but its effect description does not mention restoring HP. Do not assume that healing applies to that form based only on the shared name.

Limitations and tradeoffs

  • The effect combines periodic area damage with HP restoration, but the wielder suffers a 50% damage decrease.
  • It is a temporary quest form rather than a normally levelable long-term weapon.

Common mistakes to avoid

  • Expecting the effect to trigger more often than once every 8 seconds.
  • Ignoring the 50% wielder damage decrease when judging its attack value.
  • Assuming a related form with the same name also restores HP.

Effects and reference details

Refinement effects

R1 When a Normal, Charged, or Plunging Attack hits an opponent, it will release an Accursed Spirit, dealing AoE DMG equal to 180% of ATK and restoring 100% of ATK as HP. This effect can be triggered once every 8s. The DMG done by this weapon's wielder is decreased by 50%.
