Prized Isshin Blade

Temporary quest-form sword with a periodic area hit attached to ordinary attacks.

Introduced in v2.8

The Prized Isshin Blade releases an Accursed Spirit when a Normal, Charged, or Plunging Attack hits, dealing area damage equal to 180% of ATK once every 8 seconds. Its wielder’s damage is decreased by 50%, so consider it when the periodic area effect is useful and the wielder’s damage is not the priority. This is a temporary story-quest form.

Understand Prized Isshin Blade

Useful when…

  • Triggering its periodic area damage while landing Normal, Charged, or Plunging Attacks.
  • Using a temporary quest weapon form without treating it as a normally leveled sword.

What triggers the effect?

A hit from a Normal, Charged, or Plunging Attack releases an Accursed Spirit that deals area damage equal to 180% of ATK. The effect can trigger once every 8 seconds. The weapon also decreases the wielder’s damage by 50%, which is a substantial drawback if that character is expected to deal damage.

When is it practical to use?

The effect is tied to attack hits, so a wielder using one of the listed attack types can trigger it. Its area damage may be useful when opponents are grouped, but the trigger still has an 8-second limit. Treat the blade as a temporary story-quest form rather than ordinary equipment progression; quest weapon forms do not inherit ordinary leveling.

What is the main tradeoff?

The periodic 180%-of-ATK area hit comes with a 50% decrease to the wielder’s damage. Consider whether that cost outweighs the effect in the situation at hand; the supplied weapon details do not specify a way to remove the decrease or improve the trigger interval.

How does its related form differ?

A related Prized Isshin Blade form has the same listed trigger, area damage, cooldown, and 50% damage decrease, plus an effect that restores HP equal to 100% of ATK. That healing is not listed for this form, so do not assume this blade restores HP.

Limitations and tradeoffs

  • Adds a 180%-of-ATK area hit on a qualifying attack hit, limited to once every 8 seconds.
  • Decreases the wielder’s damage by 50%.
  • The compared form includes an ATK-scaled HP restoration effect that this form lacks.

Common mistakes to avoid

  • Assuming every attack type triggers the effect; only Normal, Charged, or Plunging Attack hits are specified.
  • Expecting the Accursed Spirit to trigger more than once every 8 seconds.
  • Assuming this form restores HP; the compared form has that additional effect, while this one does not.
  • Treating the temporary quest form as a normally leveled sword.
