Avalonia/Blissia

Avalonia/Blissia is two long swords connected together at the handles much like the signature Double-Bladed Scimitar weapon of Valenar elves. This weapon has to the ability to change the size of the sword blades magically. When the weapon is at its smallest configuration it looks like double ended daggers for ease of travail and concealment. It can be used as is dealing 2d4 Piercing Damage and still hold the properties; Finesse, Light, Thrown (range 20/60). When "one" blade is fully extended it acts as a normal Longsword dealing 1d8 Slashing Damage with the properties: Versatile (1d10). When both blades are fully extended its damage dealing potential became greater dealing 2D8 Slashing Damage with the properties requiring Two-Handed in order to wield the weapon in this configuration and can be thrown as like a Javelin for dealing 2D4 Piercing Damage with the required properties: Thrown (range 30/120) while in this configuration that weapon gives the wielder an innate second strike to same or adjacent within 5ft. of the primary target.

The weapon binds to its wielder and will always materialize to the owner's side if dropped lost or stolen. Avalonia/Blissia can also copy spell as an enchantment to the blade to enforce it's cutting power once the wielder uses a spell. The enchanted magical ability of the spell will be half of the spell maximum damage. (example: Character cast Firebolt 1d10 damage. Avalonia/Blissia enchants itself with +5 fire damage. Enchantment damage can increase with each 5th level (2d10), 11th level (3d10), and 17th level (4d10) minus half of the spell max damage.)

Even though both blades can change their length independently at the wielder thought. The swords can never be separated into two separate weapons. However, the weapon can be used as a stuff weapon when both blades are fully extended. All classes can use this weapon providing the character meets the Attunement Requirements. 

Proficiency with a Longsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
