Arclight vs Ardelia

Arclight vs Ardelia — two support-side (enabler / buffer / SP battery) Operators (Electric vs Nature) competing for the same roster slot.

TL;DR — Quick Pick

Pick Arclight if…

  • You need a Electric Support Operator and Arclight's kit matches your account gap.
  • You prefer Arclight's SP Recovery + Electric Infliction identity over Ardelia's HP Treatment + Corrode.
  • Arclight is the Electric SP battery and Electric Infliction enabler Zhuang Fangyi teams use when the premium support line is incomplete.

Pick Ardelia if…

  • You need a Nature Support Operator and Ardelia's kit matches your account gap.
  • You prefer Ardelia's HP Treatment + Corrode identity over Arclight's SP Recovery + Electric Infliction.
  • Ardelia shows up across Mi Fu, Zhuang Fangyi, Laevatain, Last Rite, and Yvonne teams as sustain-plus-amp — keeping Monument attempts alive while still contributing buff uptime, which is why she is not treated as a pure healer flex.
Verdict

Arclight and Ardelia are both Support investments that answer different account needs across Electric and Nature. Arclight shines when Arclight is the Electric SP battery and Electric Infliction enabler Zhuang Fangyi teams use when the premium support line is incomplete. Ardelia is the better commit when Ardelia shows up across Mi Fu, Zhuang Fangyi, Laevatain, Last Rite, and Yvonne teams as sustain-plus-amp — keeping Monument attempts alive while still contributing buff uptime, which is why she is not treated as a pure healer flex. Compare signature builds, team requirements, and your existing supports before pulling either.
