Traits
Iona's weapon attacks are magical. When Iona hits with any weapon, the weapon deals an extra 6d8 radiant damage (included in the attack).
Iona knows if it hears a lie.
Iona has advantage on saving throws against spells and other magical effects.
Actions
Iona makes two greatsword attacks.
Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit: 22 (4d6 + 8) slashing damage plus 27 (6d8) radiant damage.
Ranged Weapon Attack: +13 to hit, range 150/600 ft., one target. Hit: 15 (2d8 + 6) piercing damage plus 27 (6d8) radiant damage. If the target is a creature that has 100 hit points or fewer, it must succeed on a DC 15 Constitution saving throw or die.
Iona releases its greatsword to hover magically in an unoccupied space within 5 feet of it. If Iona can see the sword, Iona can mentally command it as a bonus action to fly up to 50 feet and either make one attack against a target or return to Iona's hands. If the hovering sword is targeted by any effect, Iona is considered to be holding it. The hovering sword falls if Iona dies.
Iona touches another creature. The target magically regains 40 (8d8 + 4) hit points and is freed from any curse, disease, poison, blindness, or deafness.
Legendary Actions
Iona magically teleports, along with any equipment it is wearing or carrying, up to 120 feet to an unoccupied space it can see.
Iona emits magical, divine energy. Each creature of its choice in a 10-foot radius must make a DC 23 Dexterity saving throw, taking 14 (4d6) fire damage plus 14 (4d6) radiant damage on a failed save, or half as much damage on a successful one.
Iona targets one creature it can see within 30 feet of it. If the target can see it, the target must succeed on a DC 15 Constitution saving throw or be blinded until magic such as the lesser restoration spell removes the blindness.

Iona's spellcasting ability is Charisma (spell save DC 25). It can innately cast the following spells, requiring no material components:
