Moonblade

Of all the magic items created by the elves, one of the most coveted and fiercely guarded is the moonblade. Long ago, many elven noble houses claimed such a blade. Every member of the family had the choice of attempting the bonding ritual. The sword chooses its bearer and remains bonded to that person for life. When the bearer dies their essence is drawn into the moonblade and adds to its power. Another heir can then claim the blade. If no worthy heir exists, the sword lies dormant, waiting to be found.

Over the centuries, some blades have faded from the world, their magic lost as family lines have become extinct. Other blades have vanished with their bearers during great quests. A moonblade won't serve anyone it regards as craven, erratic, corrupt, or at odds with preserving and protecting elvenkind. If the blade rejects you, you make ability checks, attack rolls, and saving throws with disadvantage for 24 hours. If the blade accepts you, you become attuned to it and a new rune appears on the blade. A moonblade has one rune on its blade for every master it has served. You remain attuned to the weapon until you die or the weapon is destroyed.

Moonblade
Weapon (longsword), legendary (requires attunement by an elf or half-elf of neutral good alignment)

Properties.

The sword grants a +3 to attack and damage rolls.

War Leader. The bearer can use an action to cause his or her voice to carry clearly for up to 300 feet until the end of the bearer's next turn.

The blade functions as a Dancing Sword.

Sentience.
A moon blade is a sentient neutral good weapon with an Intelligence of 12, a Wisdom of 10, and a Charisma of 12. It has hearing and darkvision out to a range of 120 feet. The weapon communicates by transmitting emotions, sending a tingling sensation through the wielder's hand when it wants to communicate something it has sensed. It can communicate more explicitly, through visions or dreams, when the wielder is either in a trance or asleep.

Personality.
Every moonblade seeks the advancement of elvenkind and elven ideals. Courage, loyalty, beauty, music, and life are all part of this purpose. The weapon is bonded to the family line it is meant to serve. Once it has bonded with an owner who shares its ideals, its loyalty is absolute.

If a moon blade has a flaw, it is overconfidence. Once it has decided on an owner, it believes that only that person should wield it, even if the owner falls short of elven ideals.

Note: A Moonblade can only have a maximum of +3 attack and damage bonus when all properties are applied. Example: if it had the properties of +2 attack and damage and Defender those don't stack to +5.
