At the end of the duration, the Sea-Dyed Foam will explode, dealing DMG to nearby opponents based on 90% of the accumulated healing. (This DMG is calculated similarly to Reactions such as Electro-Charged, and Superconduct, but it is not affected by Elemental Mastery, Character Levels, or Reaction DMG Bonuses). Only one Sea-Dyed Foam can be produced every 3.5 seconds. Each Sea-Dyed Foam can accumulate up to 30,000 HP (including overflow healing). There can be no more than one Sea-Dyed Foam active at any given time. This effect can still be triggered even when the character who is using this artifact set is not on the field."
In layman's terms, Your overhealing is stored for a few seconds to a maximum of 30,000, and once the duration ends, that stored value explodes, dealing damage to nearby enemies.
Something like this can potentially function in this game, but it would be tricky to balance the numbers just right. Someone would end up needing to math out the DPS relationship with this overheal attack vs just direct DPS, and it would probably need to be limited by some factor like a cooldown or a gauge resource or something.
