CoreWarrior Goddess of Sun and Thunder

Fu Xuan's Ultimate can provide team-wide healing for the 15% team-wide CRIT DMG buff, albeit unreliable since the buff only lasts for 2 turns. As she currently does not have any other buffing option. Other 2-Pc sets have a rather small impact, this is the best set for her as SPD is also useful for her.

2PCIncreases SPD by 6%.

4PCWhen the wearer or their memosprite provides healing to ally targets other than themselves, the wearer gains "Gentle Rain," which lasts for 2 turn(s) and can only trigger once per turn. While the wearer has "Gentle Rain," SPD increases by 6% and all allies' CRIT DMG increases by 15%. This effect cannot stack.

Ensure your Fu Xuan is tanky enough to survive by prioritizing HP% and DEF%. Next, try to hit key Speed breakpoints (121 and 134) through the combination of Speed boots, SPD 2-piece set, and sub-stats. Also, it is not recommended to use more than 1 DEF% main stat relic. Ideally, you want to use HP% as the main stats and hunt for DEF% on your subs. If you want numbers, aim for 6500-8000 HP (with Matrix Active) and 1400-1600 DEF and then focus on Speed.

The DMG dealt by Fu Xuan's Ultimate will increase by 200% of this tally of HP loss. This tally is also capped at 120% of Fu Xuan's Max HP and the tally value will reset and re-accumulate after Fu Xuan's Ultimate is used.

Seele team

Quantum · The HuntPlays Sustain

Seele takes an extra turn on a kill, so the team spends everything on making the first hit land: a Quantum Weakness implant, an action advance, and a shield.

Blade team

Wind · HP scalingPlays Sustain

Blade needs to lose HP to hit hardest and needs to survive doing it, so the team carries both a healer and a shielder rather than a second buffer.

Acheron charges her Ultimate off debuffs other characters apply, so the team runs two more Nihility units and a sustain that never needs a Skill Point.
