Albitr

Magic Weapon. Albitr is a magic weapon that grants a +3 bonus to attack and damage rolls made with it. The sword also functions as a Vorpal Sword, a Defender, and a Sword of Sharpness

Random Properties. The sword has the following randomly determined properties:

• 2 minor beneficial properties
• 1 major beneficial property
• 2 minor detrimental properties

Blessings of Corellon. If you are an elf attuned to the sword, you gain the following benefits:

• The range of your darkvision increases by 60 feet.
• Your trances take one hour instead of four
• You can’t be charmed

Travel the Wilderness. You can use an action to touch the sword to a tree and cast the teleport spell from the sword. If your intended destination is in a forest, there is no chance of a mishap or arriving somewhere unexpected. You can't use this property again until 3 days have passed.

Summon Elf. You can use an action to call forth an elfshadow, provided that you don't already have one serving you. The elfshadow appears in an unoccupied space within 120 feet of you. It uses the statistics for a shadow from the Monster Manual, except it is neutral, immune to effects that turn undead, and doesn't create new shadows. You control this creature, deciding how it acts and moves. It remains until it drops to 0 hit points or you dismiss it as an action.

Curse. The sword bears a curse that affects any nonelf that becomes attuned to it. Even if the attunement ends, the curse remains. With each passing day, the creature's physical appearance and stature become more elflike. After seven days, the creature looks like a typical elf, but the creature neither loses its racial traits nor gains the racial traits of an elf. The physical changes wrought by the sword aren't considered magical in nature (and therefore can't be dispelled), but they can be undone by any effect that removes a curse, such as a Greater Restoration or Remove Curse spell.

Destroying the Sword. The only way to destroy the sword is to have an orcish god tear the sword in half.
