New Class Idea

[ADVSS]

Dark Knight was a class in FF 3, which is before Cecil who was in F4. Cecil uses a Dark Sword, which are magic swords imbued with darkness and more closely resemble a European long sword or maybe a bastard sword and not a katana. Mystic Knight (which is different than Rune Knight, the class of Celes from FF6) didn't appear until FF5. Also, while not super explicit as to classes, Leon from FF2 is classified/considered a Dark Knight.

Just wanted to clear that up.

If youre talking about the ds remake yeah they called it dark knight and heavilly modified what it really did in that game.
The same exact class from the famicon version was a magic knight, which actually used level 1 white magic and used katana like the murasame etc. What i remember most about them is the need to use these swords in a specific pudding filled cave where the enemies would continuously multiply unless cut by one of these swords. Cecil does use "dark swords" but notice how the icon for them looks....exactly the same as edge the ninja's katana icon? At least it was that way in the original snes version

the ff3 version was usually translated to m.knight, which could mean mystic or magic also
