| Character | Explanation |

Long May Rainbows Adorn the Sky is amazing for Hyacine since the Light Cone provides her with SPD, a stat she needs to utilize her Bonus Ability. The rest of the Light Cone's effects also synergize well with her kit. |

Long May Rainbows Adorn the Sky is great for Support Remembrance characters who could heal and benefit from the SPD boost the Light Cone provides. The increase in the DMG taken by enemies and additional DMG is nice to have as well.
Support Remembrance characters who pair well with other high HP characters, even if they can't heal, benefit from this Light Cone.
Long May Rainbows Adorn the Sky provides Hyacine with SPD, which she needs to utilize her Bonus Ability. This Light Cone also allows her to deal extra damage since her kit lets her increase her allies' max HP.
Increasing the DMG taken by all enemies when the memosprite uses their skill is also great since it allows Hyacine to provide a useful debuff for the team instead of just being a healer.
Long May Rainbows Adorn the Sky is great for Support Remembrance characters who benefit from SPD and can keep their allies' HP high to utilize the Light Cone's effects.
If the character doesn't need SPD or can't utilize the Light Cone's HP consumption effect properly, then other Light Cones would fit better for them.
