You gain a (+3) bonus to attack and damage rolls made with this magic weapon. It deals slashing damage. It can harm incorporeal creatures and objects, and its attacks are unaffected by the miss chance or similar concealment caused solely by an illusion. The sword does not automatically dispel illusions or curses.

While you are holding the sword, you and friendly creatures of your choice within 30 feet of you have advantage on saving throws against spells and other magical effects. This benefit applies only while a creature is within the aura.

Once on each of your turns when you hit a creature with the sword, you can cause the attack to deal an extra 1d8 radiant damage. You can use this property a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

When you hit a fiend or undead with the sword, that creature takes an extra 2d8 radiant damage. This damage is in addition to the sword's normal damage.

As an action, you expend the sword's charge to unleash a 30-foot-radius pulse of radiant light centered on yourself. Choose any number of creatures in the area. Each hostile creature must make a DC 18 Constitution saving throw, taking 8d8 radiant damage on a failed save or half as much damage on a successful one. Each ally in the area regains hit points equal to 30 percent of its hit point maximum, rounded down, and can immediately end one condition affecting it. You then gain spectral wings for 1 minute: you have a flying speed of 30 feet. The wings shed bright light in a 20-foot radius and dim light for an additional 20 feet. The wings vanish early if you are incapacitated.
