Typo occurs in the Monomachy buff resulting from using the Red Mage ability Corps-a-corps in PVP. The second "damage" is misspelled as "damge".
This occurred for me on training dummies in the Wolves' Den Pier and against other players in Crystalline Conflict. I have not tested it elsewhere but I would assume it is the same in other PVP modes as it is a PVP buff.
