“The ‘tortoise’ galaxies are those that slooowly give birth to new stars. The ones that use up their fuel reserves in an instant, are the ‘hare’ galaxies.”
Asta is a free 4-star support who raises the whole team's ATK with her Talent and the whole team's SPD with her Ultimate. She fits into almost any team, from the early game all the way to hard endgame content, so she is well worth the materials it takes to build her.
Best for newer players who don't have limited Harmony characters yet, and for Fire teams or teams with two damage dealers. If you already own strong 5-star supports, Asta will rarely win a team slot.
None of Asta's buffs scale off her stats, only off her Trace levels. So just build her tanky with HP% and DEF%, then add SPD so she acts more often and Energy Regeneration Rate so her Ultimate comes up sooner.

SPD Feet and an Energy Regeneration Rate Rope are the standard picks, because Asta wants to act fast and get her Ultimate up early. On the Body, go for HP% first, though DEF% works too. For the Planar Sphere, HP%, DEF% or Fire DMG Boost are all fine, depending on whether you want her tankier or dealing a bit more damage.
HP% and DEF% are equally good. You only need Effect RES up to 30% if you use Broken Keel.
Her Talent sets how much ATK the team gets and her Ultimate sets how much SPD, so level those two first. A moderate Skill level is enough, and it helps her break Fire-weak enemies. Basic ATK is mostly there to recover Skill Points, so you can leave it at base level.
Ignite raises all allies' Fire DMG by 18% while Asta is on the field, so unlock it first. Sparks lets her Basic ATK inflict Burn. Constellation raises Asta's DEF based on how many Charging stacks she has.
E1 adds one extra hit to her Skill, giving her another chance to collect Charging stacks. E2 stops Asta from losing Charging stacks on the turn right after she uses her Ultimate, so the ATK buff lasts longer. E4 raises her Energy Regeneration Rate by 15% while she has 2 or more Charging stacks. E6 reduces the stacks she loses each turn by 1, which keeps the buff up much more steadily and makes E4 active more often.
Just by being on the field, Asta raises the whole team's Fire DMG through Ignite, and Himeko gets the most out of it. Topaz & Numby is the second damage dealer and Fu Xuan keeps everyone alive. In this team Asta can wear Planetary Rendezvous to boost her Fire teammates' DMG even more. Hook also inflicts Burn and deals more DMG to Burned targets, so she can take Himeko's place.
Makes great use of the SPD from Asta's Ultimate to stack more Arcana on enemies, though it costs more Skill Points than pairing her with Ruan Mei. The Burn from Asta's Basic ATK also lets Black Swan apply more Arcana stacks per attack.
Asta only has to be on the field for Ignite to boost Himeko's Fire DMG, so the two work really well together.
Like Himeko, Hook inflicts Burn and deals more DMG to enemies that are already Burned.
The second damage dealer in the Fire team. Asta is good at supporting teams with two damage dealers.
Can implant a Fire Weakness on enemies. When an enemy has a Fire Weakness, each of Asta's hits on it gives her 1 extra Charging stack.
Asta's Ultimate gives a big flat SPD boost, and Silver Wolf LV.999's Traces can make use of that SPD. In a regular team with Silver Wolf LV.999, Asta is on the weak side, but in runs without a healer or shielder, her Ultimate together with Dance! Dance! Dance! pushes the whole team's turns forward a lot.
Covers the sustain slot in the Fire team with Asta.
Her Talent, Astrometry, gives Asta 1 stack of Charging for every different enemy she hits, plus 1 more if the enemy has a Fire Weakness. Each stack raises the whole team's ATK, up to 5 stacks. Starting from her second turn, she loses 3 stacks at the start of every turn, so you need to keep attacking to hold the buff. Even against a single enemy, Asta attacks every turn, so she always keeps at least 1 stack, or 2 if the enemy is weak to Fire.
Her Skill, Meteor Storm, hits the target you pick and then Bounces 4 more times to random enemies. Against a big group, the Bounces land on lots of different enemies and Charging stacks build up very quickly, with a bit of luck involved. Against a single enemy, all 5 hits land on it, and the total Toughness damage is about the same as many characters' single-target Ultimates. That makes Asta very good at Weakness Break for a support, especially against Fire-weak enemies.
Her Ultimate, Astral Blessing, raises the SPD of all allies, Asta included, for 2 turns. Its real strength is how it pushes the whole team further up the turn order. The easiest trick: turn on Display Action Values in the settings, and the numbers in the turn order show how far away the next turn is. The bigger the number, the more value you get from using her Ultimate. Also, if you use her Ultimate during an ally's turn before they act, that ally seems to get an extra turn of the SPD buff. It is really a safety net that keeps you from wasting one turn of the buff.
Ignite raises all allies' Fire DMG by 18% while Asta is on the field, a perfect fit for Fire teams. Sparks gives her Basic ATK an 80% base chance to Burn the enemy for 3 turns. The Burn damage itself is close to nothing, but it is a debuff that helps some teammates. Constellation raises Asta's DEF by 6% per Charging stack, so she survives longer.
