So, is that a dagger? (In the new concept art.)

Also for those arguing this is the leviathan WHM wand, not only is it not being held the proper direction, it is also not at all the color scheme of Leviathan weapons. Also note the weapons others are using, with the possible exception of the BLM, none of them are using the Leviathan weapons. Just because they are fighting him does not mean they are all going to be drawn with his weapons. (In fact that would make less sense.)

Plus there are already 2 people with 2h Rod/Staff weapons, so WHM and BLM are already accounted for.
