Dié is the signature weapon of Lana Mulberry. It takes the form of a great axe, capable of condensing to the shape of a shield for defense and travel, splitting apart for dual wielding purposes, and extending its blades into a fan shape for longer ranged Dust attacks.
In terms of Dust, Dié most commonly is used in conjunction with Ice Dust in all modes, allowing for sundering slashes with freezing prowess in axe form, and allowing for ranged icicle attacks in fan mode. Wind Dust may also be used in order to create strong gales to attack and disorient foes, or grant the user added mobility and maneuverability.
- Dié is the Chinese word for "Butterfly". This can refer to the fact that the weapon can split in half, similar to the two wings of a butterfly.
