Myrtenaster

The Myrtenaster is Weiss' weapon of choice. It is a Multi Action Dust Rapier (MADR) that seems to act as a focus for Weiss' magic. Myrtenaster is standard sized and gray. The hilt forms in 4 prongs that act as a guard around a revolver's chamber-like mechanism, in place of the usual basket hilt. Weiss controls this mechanism with her hands, and can change the modes at will. There are 6 modes in total which effect Myrtenaster and the way Weiss battles. They are Red, Light Blue, Violet, White, Yellow, Blue.

The Myrtenaster is highly durable, slashing away at the Giant Armor with no side effects to the blade. Its most prominent ability lies in the revolver-like mechanism held within the hilt, which is color coded with various attributes for each mode.

Note: This is partial speculation, as it is not perfectly clear what each mode does or is fully capable of doing


 * White - Weiss' main spell, which she uses at the beginning and end of the battle. At its full potential, it is able to deliver a finisher attack, in which the weapon glows with runes imbuned on the blade, and possibly turns enemies into ice shards when defeated.
 *  Yellow -  Seems to enhance her agility, or increases attack power similar to violet.
 *  Blue -  Appears to make a repulsion seal as well as the ability to bind the opponent.
 *  Red - Appears to enhance strength or create an enhanced shield.
 *  Light Blue -   Conjures a wave of ice.
 *  Violet -  Increases attack power for a split second, dealing high damage with a slash attack.

Trivia

 * In keeping with the combination of guns and melee weapons demonstrated with Ruby's High Velocity Sniper Scythe, the Crescent Rose, some fans have called this weapon type a "Revolver Rapier".
 * Myrtenaster (Myrten Aster) is German for a family of flowers (Myrtle) that are typically found to be white, but can come in a variety of other colors.
