Asta
Situational—Asta’s team SPD Ultimate still enables Break/FUA. Ultimate “Astral Blessing” is the named payoff ability for this rotation. Best with Himeko / Firefly / Rappa. Charges from hitting Fire-weak or frequent Basics. Skip when Ruan Mei/Robin cover your SPD/Break amp.
Asta is a 4★ Fire Harmony Support. Skill “Meteor Storm” is the primary in-combat spend. Ultimate “Astral Blessing” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Astral Blessing” Increases SPD of all allies by 57 for 2 turn(s)—time it for the carry’s damage window instead of casting on cooldown out of habit.
- Skill “Meteor Storm” dumps a large single-target multiplier into one elite—this is the spend that keeps the rotation honest.
- Talent “Astrometry” implants element Weakness so Break stays online off-element—miss the stack conditions and the burst window feels empty.
- Asta can implant or force Fire-relevant Weakness from the kit itself—Break and Toughness routes stay online even when the MoC line-up did not list Fire.
Weaknesses
- Buff windows on “Astral Blessing” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
- Asta’s Skill is often the expensive part of the rotation; SP-negative teams force Basic ATKs and you lose the advance/amp that made the unit worth playing.
- As a 4★ Harmony unit, Asta is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
- Spamming “Meteor Storm” every turn without watching Skill Points strands the rest of the team—Asta is often the SP sink.
Trace Priority
Meteor Storm carries most of the kit’s damage or utility—level this first.
Astral Blessing supports the main rotation—raise after the top priority traces.
Astrometry supports the main rotation—raise after the top priority traces.
Spectrum Beam is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
Increases the wearer's Energy Regeneration Rate by 0.1% and regenerates 1 Skill Point when the wearer uses their Ultimate on an ally. This effect can be triggered once after every 2 uses of the wearer's Ultimate. When the wearer uses their Skill, the next ally taking action (except the wearer) deals 0.3% more DMG for 1 turn(s).
Why it works —Strong Harmony option for Asta; use while farming or if signature is unavailable.
5★ · Path cone
Increases the wearer's CRIT DMG by 0.32%. At the start of the battle, the wearer gains Mask, lasting for 3 turn(s). While the wearer has Mask, the wearer's teammates have their CRIT Rate increased by 0.1% and their CRIT DMG increased by 0.28%. For every 1 Skill Point the wearer recovers (including Skill Points that exceed the limit), they gain 1 stack of Radiant Flame. And when the wearer has 4 stacks of Radiant Flame, all the stacks are removed, and they gain Mask, lasting for 4 turn(s).
Why it works —Flexible alternative on the same path—equip if you already own it at higher superimposition.
4★ · Path cone
At the start of the battle and whenever the wearer's turn begins, one of the following effects is applied randomly: All allies' ATK increases by 0.1%, all allies' CRIT DMG increases by 0.12%, or all allies' Energy Regeneration Rate increases by 0.06%. The applied effect cannot be identical to the last effect applied, and will replace the previous effect. The applied effect will be removed when the wearer has been knocked down. Effects of the same type cannot be stacked.
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
When the wearer uses their Skill, the next ally taking action (except the wearer) deals 0.16% increased DMG for 1 turn(s).
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Asta enabling Hook. Hook, Firefly, Huohuo complete the dot shell.
Hook is the damage seat in this shell — build the supports around their rotation, not the reverse.
Enabler / amp piece this page is built around — keep their buffs or debuffs online every cycle.
Firefly is the damage seat in this shell — build the supports around their rotation, not the reverse.
Huohuo covers healing (and often Energy / cleanse) so the carry can stay on-curve.

Eidolons
When using Skill, deals DMG for 1 extra time to a random enemy.
Is it worth getting?
Small 4★ bump: When using Skill, deals DMG for 1 extra time to a random enemy. Take dupes when they appear on rate-up; never the reason you pull the banner.
After using her Ultimate, Asta's Charging stacks will not be reduced in the next turn.
Is it worth getting?
Kit add-on: After using her Ultimate, Asta's Charging stacks will not be reduced in the next turn. Evaluate against your supports—pull only if that specific clause solves a problem you actually hit.
Skill Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15.
Is it worth getting?
Skill + Talent levels only (+2). Free if you roll into it; never spend currency aiming for E3.
Asta's Energy Regeneration Rate increases by 15% when she has 2 or more Charging stacks.
Is it worth getting?
Side-grade: Asta's Energy Regeneration Rate increases by 15% when she has 2 or more Charging stacks. Happy if it drops; not a planned stopping point.
Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Is it worth getting?
Ultimate + Basic ATK levels only (+2). Skip as a goal—grab it if you overshoot toward E6, never hard-pity for it.

Is it worth getting?
Whale ceiling: Lowers a stack / resource requirement for the main payoff. Only chase if Asta is your dedicated Harmony main and E0–E2 already feel finished.
