Asta is a Fire-element character who follows the Path of Harmony. She offers up to a 70% ATK boost through her Charging stacks and grants a massive +50 SPD to the entire team with her Ultimate. While she’s easy to use, her Skill needs to hit multiple different enemies to fully stack her Charging, making it somewhat inconsistent.
Despite the randomness of her Skill’s targeting, Asta is still a highly regarded support—especially for F2P Hypercarry and DoT teams. Her SPD buff is also valuable for units equipped with the Glamoth set, helping them reach the SPD threshold for maximum DMG amplification, even if only for a limited duration.
Best Cavern Relics
(2) Increases SPD by 6%.
(4) When the wearer uses their Ultimate on an ally, SPD for all allies increases by 12% for 1 turn(s). This effect cannot be stacked.
Messenger Traversing Hackerspace is Asta’s best-in-slot Cavern Relic, as it not only boosts her own SPD but also grants a temporary SPD increase to the entire team—enhancing overall turn efficiency and synergy.
Best Planar Ornaments
(2) Increases the wearer's Energy Regeneration Rate by 5%. When the wearer's SPD reaches 120 or higher, the wearer's action is Advanced Forward by 40% immediately upon entering battle.
Sprightly Vonwacq is Asta’s best Planar Ornament set, as it gives her a high chance to act first at the start of battle. This allows her to immediately use her Skill and begin stacking Charging for a team-wide ATK boost. It also helps with her energy regeneration and Ultimate uptime, enabling her to consistently provide up to +60 SPD to the team for 2 turns.
(2) Increases the wearer's Effect RES by 10%. When the wearer's Effect RES is at 30% or higher, all allies' CRIT DMG increases by 10%.
If Asta reaches the required Effect RES threshold, she can grant her team a 10% CRIT DMG boost, further enhancing overall team damage output.
(2) Increases the wearer's Energy Regeneration Rate by 5%. If the wearer is not the first character in the team lineup, then increases the ATK of the first character in the team lineup by 12%.
Lushaka is still a viable set, as it boosts the ATK of the team's main DPS—provided they are placed in the first slot of the team lineup.

info
Since Asta’s ATK and SPD buffs don’t scale with her own stats, it’s more efficient to prioritize relic stats that support her survivability, speed, and Ultimate uptime. Ideally, equipping HP% or DEF% on her body and sphere pieces is recommended, as Harmony characters tend to have slightly higher aggro values—making extra durability especially valuable.
Best Light Cones
SourceStellar Warp, Light Cone Event Warp, Starlight Exchange, Stellar Convergence
Heir
Increases the wearer's Energy Regeneration Rate by 10~18% 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 30~50% more DMG for 1 turn(s).This Light Cone improves Asta’s Ultimate uptime, allowing her to activate it more frequently when needed. The bonus DMG buff to the next ally is easily triggered, as long as the main DPS has the second-highest SPD after Asta—making it a reliable support option in speed-tuned teams.

Cannot Stop It!
When the wearer uses their Ultimate, all allies' actions are Advanced Forward by 16~24%.Dance! Dance! Dance! is extremely valuable in endgame content, especially during critical situations. Its Advance Forward effect gives the entire team a chance to act sooner, potentially turning the tide of battle and preventing unfavorable outcomes.
Secret
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 10~20%, all allies' CRIT DMG increases by 12~24%, or all allies' Energy Regeneration Rate increases by 6~12%. 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.
The chosen buff from the three stat options is applied randomly at the start of combat and cannot be changed unless another character with the same Light Cone is present. The selected buff remains active for the entire duration of the battle.
Flustered
After entering battle, increases all allies' Break DMG dealt by 16~24%. Abilities of the same type cannot stack.This Light Cone is her best option for Break DMG teams, as it provides a Break DMG boost to all allies.
