Aino
Aino is a rare bargain: a 4-star Hydro unit who can shoulder Hydro application and EM buffing for a whole range of reaction teams, from Lunar-Charged to Lunar-Bloom. Being 4-star, almost anyone can own and max her quickly without needing fancy weapons or artifacts. What matters most is enough Energy Recharge to keep her Burst up; Silken Moon's Serenade is the standard but Noblesse Oblige or Instructor work fine too. For newer players she's well worth investing in early, since she stays useful across many teams for a long time.
