Description of Known Issues
Situation 1: I'm using food items, but Arlecchino's is not healing, but my food items are reducing and I see the message [Maximum HP or Fullness reached].
This issue happens when you are in combat. When in combat, Arlecchino is only able to heal via her Elemental Burst. Any food or HP items used will be consumed by the next party member who is not at full HP instead.
Situation 2: Intended Healing Mechanic
By design, Arlecchino cannot receive healing from external sources, such as food or other characters, during combat. She can only be healed by her own Elemental Burst. If you find her Elemental Burst is not providing healing, please contact Customer Support with video evidence for further investigation.
