The Ashblazing Grand Duke

Follow-up attack damage relic set

Introduced in v1.5

The Ashblazing Grand Duke boosts Follow-Up ATK damage with two pieces. With four pieces, each damage instance from a Follow-Up ATK grants the wearer 6% ATK, up to 8 stacks, for 3 turns; the stacks are removed the next time the wearer uses a Follow-Up ATK. Consider it for a wearer whose damage comes from Follow-Up ATKs, while accounting for the reset when those attacks recur.

Understand The Ashblazing Grand Duke

Useful when…

  • Increasing a wearer's Follow-Up ATK damage.
  • Building ATK stacks from multi-hit Follow-Up ATKs, while planning around the reset on the next Follow-Up ATK.

How do its effects work?

Two pieces increase damage dealt by Follow-Up ATKs by 20%. With four pieces, using a Follow-Up ATK increases the wearer's ATK by 6% for each time that attack deals damage. The effect can stack up to 8 times and lasts 3 turns; the next time the wearer uses a Follow-Up ATK, the effect is removed.

Who benefits from four pieces?

The set is most relevant when a wearer's damage includes Follow-Up ATKs: the two-piece effect directly buffs that attack type, and each damage instance from a Follow-Up ATK can add an ATK stack. A Follow-Up ATK with several damage instances can therefore build stacks more quickly, subject to the 8-stack cap. By comparison, As Navigator Isee Sees It buffs Skill and Ultimate damage through stacks gained on combat entry or Skill use; that is a different attack profile, not an automatic substitute.

What limits the stacks?

Do not treat the ATK stacks as permanent: they last 3 turns and are removed the next time the wearer uses a Follow-Up ATK. The set information does not promise a fixed stack count from each attack; stack gain depends on how many times that Follow-Up ATK deals damage.

Limitations and tradeoffs

  • The two-piece bonus applies specifically to Follow-Up ATK damage.
  • The four-piece ATK stacks are removed at the next Follow-Up ATK and expire after 3 turns.

Common mistakes to avoid

  • Assuming every Follow-Up ATK adds the same number of stacks regardless of its damage instances.
  • Ignoring that the next Follow-Up ATK removes the accumulated ATK effect.
