Sword of Goujian

Weapon (shortsword), artifact (requires attunement)

The sword of goujian is a magic, sentient short sword that grants a +3 bonus to attack and damage rolls made with it. It counts as a sword of sharpness.

• Wisdom of Goujian. While carrying this sword you gain advantage on Wisdom saving throws and all skill checks related to Wisdom.
• Biding Time. Whenever you use the ready action to make an attack you may immediately make one additional attack.
• Never Forget. Anytime you use this weapon to deal damage to a target that has at any time in the past dealt damage to you, you deal an extra 4d6 slashing damage, these dice are not maximized by sharpness.
• Sentience. The Sword of Goujian is a sentient Lawful Evil weapon with an Intelligence of 16, Wisdom of 18, and Charisma of 16. It has normal hearing and vision up to 60 feet. The weapon can read and speak all languages as though under the effects of a comprehend language spell. It can also communicate telepathically with the wielder.
• Personality. While the blade will never compel you to overt evil acts, it will always encourage you to be ruthlessly pragmatic, to reward loyalty, to punish betrayal, and to never leave a loose end behind. The sword despises chaos and disorder and will vocally berate the user for such actions.
• Destroying the Sword. To destroy the sword a chaotic good creature must cast wish while holding it at the site of the former Wu throne.
