CoreMessenger Traversing Hackerspace

Good team wide supportive option for characters with Ultimates which target allies. With this set equipped Ultimates are best timed carefully to ensure the Speed buff is active on key members for as long as possible.

2PCIncreases SPD by 6%.

4PCWhen the wearer uses their Ultimate on an ally, SPD for all allies increases by 12% for 1 turn(s). This effect cannot be stacked.

Also works

Planar ornaments

Sphere and rope · 2-piece only

CoreSprightly Vonwacq

Incredibly strong option for buff/debuff based characters. The advance from this set allows the wearer to apply their buffs/debuffs before the rest of the team acts, accelerate rotations, allows access to ultimates closer to the start of the fight and also grants Energy Regen. A valuable stat for many supports.

2PCIncreases 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.

Asta's energy economy depends on many factors such as her rotation, Eidolons, and getting hit. Specifically, her Eidolon 1 gives 6 extra energy per Skill, Eidolon 4 grants 15% Energy Recharge, and her Eidolon 6 makes her E4 uptime more consistent. The choice of your Planar set depends on the team you use Asta in - Broken Keel for Crit teams, Penacony for Fire teams, and Fleet for DoT teams.
