Intron 7 Fina ideas: You can't hide! "If an enemy does not have an element, Fina treats the enemy as if they were Umbro typing for purposes of damage calculations." Alternate option: "Any enemy hit by Fina's weapon attacks that does not have an element is converted in to an Umbro typing."
We can't start the tea party until everyones here! Don't be late! "Fina's ultimate no longer removes guests from the tea party, instead stacking auras, when all tea party members are present they stop running around the field and instead all sit together in the center of the aura field. Field range increased by an additional X% when all members are present. Field now does all 4 elements of damage concurrently."
New friends! "Fina's ultimate gains 2 new elements. The 1st being an Umbro hedgehog, the 2nd being a Lumeno Rabbit."
Calling All Hands on Deck: "Fina's ultimate immediately summons all tea party members at once with only one button press."
These are all just ideas/suggestions of course.
