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 Charging, making it somewhat inconsistent.
Despite the randomness of her Skill’s targeting, Asta remains 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.
This is currently her best set for maintaining faster turns, allowing for quicker Charging restocks and more efficient Energy recovery to maximize Ultimate uptime.
Best Planar Ornaments
(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%.
This is her best Planar Ornament set, boosting her resistance to crowd control debuffs while granting Crit DMG to the entire team.
(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.
This set is a good alternative, providing faster Energy restoration and allowing her to take quicker turns at the start of the battle.
(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%.
This is a viable set, especially for boosting the DoT DPS positioned in the team’s first slot.

info
Since Asta’s ATK and SPD buffs don’t scale with her own stats, it’s more efficient to focus on relic stats that enhance her survivability. A minimum of 135 SPD is recommended, with at least 4,000 HP and 1,000 DEF. Ideally, equip HP% or DEF% on her Body and Sphere pieces, as Harmony characters tend to have slightly higher aggro values, making extra durability especially valuable. Lastly, use an ERR rope to maximize her Energy restoration.

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 is currently her best 5★ Light Cone, primarily for its faster Energy restoration and the ability to restore one Skill Point every two uses of her Ultimate.

Cannot Stop It!
When the wearer uses their Ultimate, all allies' actions are Advanced Forward by 16~24%.This is her best 4★ Light Cone, granting up to 24% Advance Forward, perfect for stealing turns from enemies.
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.
This Light Cone can be considered for Asta; however, the buffs it provides at the start of the battle are determined by RNG.
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.
