Hymn of the Maelstrom

Increases Healing Bonus by 4%. When performing healing, the equipping character gains the "Vatsamonga's Vatic Vintage" effect, which increases Max HP by 4% as well as increases the currently active party member's ATK by 0.4% for every 1,000 Max HP the equipping character has over 40,000. A maximum of 8% ATK can be gained in this way. This effect lasts 10s, max 3 stacks. When a nearby party member triggers a Frozen or Stellar Swirl reaction, the aforementioned Max HP and ATK boosts will be further increased by 75% for the next 5s. The aforementioned effects can still trigger even when the equipping character is not on the field.
