Data Bank

Introduced in v1.0

Data Bank increases the wearer’s Ultimate damage by 28%–56%, depending on superimposition. Its effect names Ultimate damage, not the wearer’s other attacks.

Data Bank GUIDE

Understand Data Bank

Useful when…

  • Increase damage from the wearer’s Ultimate.
  • Use when Ultimate damage is the specific attack type to improve.

What damage does it improve?

The Ultimate damage bonus is 28% at S1 and rises to 56% at S5. The description specifically names Ultimate damage; it does not state a bonus for the wearer’s other attacks.

How can you invest in it?

Promotion advances Data Bank through stages 0–6. Superimposition advances from S1 to S5, with the listed steps consuming one S1 Data Bank copy each. Superimposition increases the Ultimate damage bonus.

How do the listed Erudition effects compare?

A Dream Scented in Wheat increases CRIT Rate and boosts Ultimate and Follow-Up Attack damage. After the Charmony Fall increases Break Effect and grants Speed for two turns after the wearer uses an Ultimate. A Star That Lights the Night has an Assist Skill condition: using it restores Energy and grants Sail stacks that increase Assist Skill damage; at three stacks, each Sail stack also increases Ultimate damage. These are distinct effect packages tied to their named stats or mechanics.

Limitations and tradeoffs

  • The damage increase applies to Ultimate damage only as stated.
  • It has no stated team effect or bonus for other attack types.

Common mistakes to avoid

  • Applying the Ultimate bonus to Follow-Up Attacks or Skill damage.
  • Ignoring the Assist Skill condition when assessing A Star That Lights the Night.
