Superiority

Superiority is Serap Verzand's signature weapon. it is a longsword capable of segmenting its blade into a whip. In addition, a port at the bottom can accept different vials of powdered Dust to charge the blade with elemental effects.

Description
The weapon appears to be designed to support allies rather than lead an offensive, with its variable Dust capabilities and incapacitating whip form.

Longsword
In its longsword form, Superiority functions and looks almost exactly like its basis. The only caveat to this is the port capable of holding a vial of dust replacing the pommel at the bottom of the weapon. The blade itself also reveals the transformed mode, with numerous lines etched into it to designate the different segments of the blade. Whether or not this shows structural integrity issues, however, has not been shown.

Whip
The whip form has the blade, at the flip of a switch, segment into several different smaller blades held together by an internal system of chains. It retains the original handle and guard, in addition to its Dust functionality. By wrapping the blades around am object and pressing a button, Serap is capable of shifting the blades on the chains to further bury themselves in the target, though how this is done is unknown. Pressing this button also empties the vial of Dust loaded into the weapon.

Dust Capabilities
During his fight with Apollyon, Serap presses a button to empty the vial of lightning Dust into his whip, causing sparks to run down it and shock the Grimm. Though it is unknown what effects other variants of Dust might have, it can be assumed that they will share similar effects. For instance, using a vial of fire Dust would light the sword or whip aflame.
