Do you remember. The 21st night of September?

This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

Affinity (Affinity) skill to “batch Stack” together, and the more you accumulate, the more damage dealt and movement speed are increased, the core of an element build. When one Affinity fills, all unlocked Affinity also fill simultaneously, so the Stack ramp‑up is fast. A class MOD for Amon who want to fight with elements as the axis.

🧩 Source of the red text Earth, Wind & Fire’s famous song “September” is quoted from its opening lyric “Do you remember the 21st night of September?” (verified on Songfacts). The element (element) = a selection tied to the flamboyance of funk/soul, and the direct semantic link to the ability itself is weak, making it a “famous phrase quote” type of red text.

What kind of class MOD? (Beginner’s perspective)

Unique Effects (Mechanics)

The exclusive status +N% is a level‑dependent reference value (added 2026-08-06) The +N% below originates from Lootlemon / MentalMars. In‑game, the exclusive status values change with level (only the status type is fixed, not the numbers).

  • Measured: duration/damage types are Lv45 = +41% / Lv47 = +43%. Other MODs / other VH have the same values at the same Lv (not dependent on individual rolls or prefixes) = provisional formula value% = Lv − 4
  • With this formula, the Web’s +45% is written as a fixed value equivalent to Lv49
  • ⚠️ Whether other series numbers such as +23% / +60% follow this formula is (unverified) (CD speed series may be Lv‑independent with +23% at Lv45/47)

Elementalist: When any Affinity Skill gains a Stack, all unlocked Affinity Skills also gain a Stack. Based on the total Stack of all Affinity, movement speed increase + damage dealt +2%/Stack. Exclusive status +45% Skill Damage.
