Feixiao Best Team Compositions & Character Synergies

Robin is an incredibly powerful and versatile Harmony Support unit that was designed for Follow-up ATK teams and is Feixiao's Best Support. Robin provides a large DMG % buff as well as a huge amount of flat ATK and 25% CRIT DMG for Follow-up ATKs. Robin is reliant on teammates hitting to generate energy to keep casting her Ultimate which is perfectly synergistic with Feixiao who hits many times per turn. Robin also advances the entire team every time she uses her Ultimate which is amazing for overall damage with Feixiao as all unit turns contribute to Feixiao getting Flying Aureus stacks.

Cipher is an incredibly fast Nihility unit that launches a powerful Follow-up ATK every turn which is great for Feixiao as it helps generate stacks. Moreover, Cipher provides a 40% increased DMG taken by all enemies aura simply for existing. The overall damage increases offered by Cipher are immense and she works perfectly with Feixiao and can act as a drop in replacement for nearly any unit.

Tribbie provides a All-Type RES PEN Aura to the entire team as well as having a 30% increased DMG taken Aura on enemies from her Ultimate. Tribbie also has frequent Follow-up ATKs which help build Feixiao's Ultimate quickly and her AoE damage helps to clear groups of enemies that Feixiao would usually struggle to deal with efficiently.

Sunday is the most powerful Action Advance unit in the game currently providing a large CRIT Rate buff, a large CRIT DMG buff and a moderately sized DMG % buff while also being Skill Point Neutral.
Sunday is best played with 1 less SPD than Feixiao which can be a problem if your Feixiao is Hyperspeed as both would need to be >160 SPD which is a lot of SPD investment for Sunday. We suggest playing Sunday with non hyperspeed builds to make him more versatile for use with other units and easier to build.

Topaz is a strong unit with the the highest amount of attacks per round in the game making her an excellent battery for Feixiao. Topaz also has a 50% DMG Follow-up ATK Vulnerability through her skill Difficulty Paying? which is great for Feixiao.
Topaz’s Proof of Debt debuff lands on a random foe and needs a Skill Point to be shifted with her Skill. Without spare SP, you’ll end up either hitting the wrong target, missing out on Numby advances, or overkilling the initial target and hoping the debuff jumps to someone better when they die.

March provides both buffs, high personal damage output and a high hit frequency thanks to the Follow-up ATK March launches once per turn. The buffs March provides are 10% SPD and 60% CRIT DMG to Feixiao. March’s core mechanic Master, I've Ascended! works perfectly with the number of hits Feixiao has per turn and lets March receive action advances very frequently.

Moze is a skill point neutral debuff based sub DPS that launches very frequent Follow-up ATKs that is very synergistic with Feixiao. Moze grants 25% increased Follow-up DMG taken and increases CRIT DMG by 40% against targets with his Preystacks.
Feixiao burns through Moze’s stacks of Prey very quickly maximising his DPS and Follow-up ATK frequency. Feixiao can also hold onto her Ultimate if Prey is not active without losing DPS.

Aventurine is completely Skill Point Positive and has no issues keeping a team safe with minimal uses of his Skill. Aventurines A6 Trace Bingo! results in more Follow-up ATKs being launched and thus more Shielding when he is played in a Follow-up ATK team. Aventurine also generates stacks for his Follow-up ATKs whenever anyone with his Shields take damage which makes him launch a large number of Attacks each turn cycle making him an incredible Battery for Feixiao's Ultimate.

Both Hyacine and her Memosprite Little Ica have very high SPD resulting in a lot of overall hits from both of them over the course of a fight. While she is slightly worse than Aventurine for Feixiao teams she is still very and is the 2nd best Sustain for these teams.
