Increased Wisdom. While you are attuned to the blade, your Wisdom increases by 2 to a maximum of 24.

Vision of Kings. While you are attuned to the Argent Blade you have True Sight at a range of 60 ft.

Ruler's Command. You may, once per day, cast the Mass Suggestion. The targets of the spell must all be of the same race, or the spell will automatically fail.

Curse. While attuned to the Argent Blade you risk treading the paths of the Blade's creators. When you first attune to the Blade, and anytime you use the Ruler's Command ability, you must make a DC 20 Charisma save. If you fail you gain the following flaw: "I will do anything to gain more power". This flaw cannot be expunged except with Divine Intervention or a Wish. Failing to act in the name of this flaw will result in losing all benefits of the Blade until you betray someone you care about in the name of power.

Destroying the Argent Blade. In order to destroy the blade it must be taken to the Jade Throne Room at the heart of the old Yuan-Ti Empire. There it must be used to spill the blood of a Yuan-Ti Abomination or Anathema, then it must be struck against the Jade Throne itself, and only then will the Blade shatter and lose its power.

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