Red Mage: An upgrade to the three ranged AOEs. And some useful additions to the existing spells. Currently, the red mage has several spells which are doing the exact same effect except that it either fills the white or the black mana. And it would be cool to get some spells that use either the white or the black mana for an effect like an enemy debuff if you use the black mana and a self-buff if you use the white mana.
Edit: And a buff to Embolden.
