Blue Wizard
Class: Sorceress
The Blue Wizard is a class from the Final Fantasy series: they are technically a magic-user, but rather than learning spells the conventional way, they learn the skills of creatures in the field. This variant is more closely related to the Blue Wizard in Final Fantasy V, but I have borrowed elements from several other games in the series.

Mystic Knight
Class: Assassin
The Mystic Knights were equipped like proper fighters, but could use a round to cast a mage spell upon their sword, then when they would attack the spell effect would kick in. Obviously this is not too unlike the Assassin's spell-charging, so after several different angles I have managed to piece together a conversion I am happy with.
