Instructions
Use red elements to damage the Royal Jelly, such as Fireball, Inferno or Salamander. Characters such as Kid, Janice or Miki are all red innate characters, meaning they have access to red element spells. Only red element attacks will harm the Royal Jelly.
Use the magic spell "TurnRed." This spell will make any of your character's attacks of the red element, allowing you to damage the Royal Jelly.
Use any healing elements, such as "HealPlus" or "HealAll," if any of your party's health becomes low.
Continue to use any red element-based attack on the Royal Jelly until it is defeated.
