Her best-in-slot option. Increases Healing Bonus by 8%. After healing, gains "Hymn of the Water Imp" stacks that boost Max HP and grant the active character an ATK buff based on Vodyanitsa's Max HP. In Frozen or Stellar Swirl teams, these bonuses are further increased by 75%.
A strong HP-scaling option. After using her Burst or creating a shield, restores Energy every 2.5s and grants Elemental DMG Bonus based on Max HP. Works even when Vodyanitsa is off-field.
Provides a solid boost to HP and Healing Bonus, directly strengthening her healing output while helping her reach HP thresholds for her kit.
The most comfortable free-to-play option. At R5, using her Burst regenerates 6 Energy every 2s for 6s and restores 6% HP to all party members every 2s during that duration.
A budget support option. Switching characters grants the incoming character a 48% ATK buff at R5 for 10s. The HP substat still helps her build, though it provides less HP than Prototype Amber.
