This is a combination of Rune Knight (FFT) and Rune Fencer (FFXI) that I was inspired to make.

Rune Knights have 2 stances
Incarnation of Fire – While in this stance the rune knight uses two hands to wield his weapon and engulfs it’s blade in searing flame, in this stance his offensive abilities will cost MP, while his defensive abilities will cost TP. His damage will increase by 20% and his damage reduction will decrease by 10%.
Incarnation of Earth – While in this stance the rune knight conjures a shield made of the most solid stone while holding his blade in his other hand, in this stance his offensive abilities will cost TP, while his defensive abilities will cost MP. His damage will decrease by 10% and his damage reduction will increase by 20%.
