When the character equipping this artifact set heals a character in the party, a Sea-Dyed Foam will appear for 3 seconds, accumulating the amount of HP recovered from healing (including overflow healing). 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.
