The sword chooses its bearer and remains bonded to that person for life. If the bearer dies, another heir can claim the blade. If no worthy heir exists, the sword lies dormant. It functions like a normal longsword until a worthy soul finds it and lays claim to its power.

A moonblade won’t serve anyone it regards as craven, erratic, corrupt, or at odds with preserving and protecting the balance of life and death. 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. You remain attuned to the weapon until you die or the weapon is destroyed.

A moonblade has one rune on its blade for each master it has served (typically 1d6 + 1). Each rune grants the moonblade an additional property:

• You gain a +3 bonus to attack and damage rolls made with this magic weapon. The first time you attack with the sword on each of your turns, you can transfer some or all of the sword’s bonus to your Armor Class, instead of using the bonus on any attacks that turn. For example, you could reduce the bonus to your attack and damage rolls to +1 and gain a +2 bonus to AC. The adjusted bonuses remain in effect until the start of your next turn, although you must hold the sword to gain a bonus to AC from it.
• The moonblade scores a critical hit on a roll of 19 or 20.
• While attuned to the artifact, you have resistance against cold damage.

Sentience

A moonblade 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 its ideals: courage, loyalty, beauty, music, and life are all part of this purpose. Once it has bonded with an owner who shares its ideals, its loyalty is absolute. If a moonblade 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 its ideals.

 

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