Aleph — Review & Analysis

Aleph
Aleph is a 6★ Intellect support/buffer built around the Moxie engine and the team-wide Answer buff. Declaration of Ideals blankets the whole squad with Answer for 3 rounds, while her passive turns her into a Moxie battery (cap +2, +4 each round, 25% refund). Her ultimate Memorizes 2 Incantations to replay value, and her single-target Mental attacks let her double as a sub-DPS.
Strengths
  • Declaration of Ideals grants the whole team Answer for 3 rounds, with extra stacks available via Moxie.
  • Powerful Moxie battery: cap +2, +4 at round start, 25% chance to refund 1 Moxie — fuels the entire team.
  • Ultimate Memorizes 2 Incantations for extra tempo and value; Power Discipline hits up to 400% Mental DMG when leaning sub-DPS.
  • Intellect stands outside the Afflatus counter cycle — it counters nothing, but she gets +8% self DMG on entering combat and Interpretation on enemies.
Weaknesses
  • Intellect stands outside the Afflatus counter cycle — no Afflatus deals bonus DMG to her, and she deals no bonus DMG back either.
  • Heavily reliant on Moxie stacking and Answer/Case synergy; needs the right team to fully shine.
  • Her attacks are single-target only, with no personal AoE nuke, so she can't be a pure carry.
Build Priority

Level Declaration of Ideals (team-wide Answer buff) and her ultimate first, since Aleph's value lies in buffing and replaying Incantations; raise Power Discipline afterward if you want to lean into her sub-DPS side. For Psychubes, she's a buffer/support, so favor survivability and utility options (keep Aleph alive to feed Moxie all fight); only consider ATK/DMG-oriented Psychubes if you build her as a damage dealer.

Teams with Aleph

Impromptu Surge · Impromptu

Barcarola, Aleph and Kiperina all tap into Impromptu — combining it across three kits at once outperforms any single carry doing it alone. Name Day keeps the line-up alive with Heal so that payoff has time to land.

Teams →
Impromptu Eureka Stack · Impromptu

Paper Heron spends her own Eureka to add extra hits and bonus DMG% onto Impromptu Incantation, the shared follow-up counter that Barcarola, Aleph and Kiperina each feed independently through their own kits — stacking all four Impromptu carries at once compounds the same counter instead of splitting the mechanic across two separate teams. Kiperina's Shield and Cleanse cover the survivability a dedicated healer would otherwise provide.

Teams →
Extra Action Chain · ExtraAction

Flutterpage's second Incantation grants herself an actual bonus turn — 【Continuous Action I】 — every time it lands, and 37's passive banks Eureka both from her own casts and whenever any ally takes an extra action, cashing 5 Eureka in for a free 【Supplementary Formula】 follow-up hit. Fatutu's mass dispel and 【Spirit Shell】 stacks keep the front line clean enough to keep re-casting, and Pickles' Ultimate hands the whole team a DMG Dealt +30% buff that cashes in on every extra swing the other two generate.
