Can we get a Zantetsuken for DRK's from Odin?

[Alahra]

Yes, it does. All of the FFXIV in house products (weapons from primals for example) have no external source to keep consistent with. If they had made Midgardsomr in the game that looked like a chicken then it would be seemingly awkward (he also adheres to his Norse Mythology counterpart).

You do know that Zantetsuken isn't from Norse Mythology, right? The Odin in FF isn't much like the Norse Wotan except for the name, his spear (Gungnir), and Sleipnir.
