Arrigal

Assassinate. During its first turn, Arrigal has advantage on attack rolls against any creature that hasn't taken a turn. Any hit Arrigal scores against a surprised creature is a critical hit.

Evasion. If Arrigal is subjected to an effect that allows him to make a Dexterity saving throw to take only half damage, Arrigal instead takes no damage if he succeeds on the saving throw, and only half damage if he fails.

Sneak Attack. Once per turn, Arrigal deals an extra 14 (4d6) damage when he hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of Arrigal that isn't incapacitated and Arrigal doesn't have disadvantage on the attack roll.

Multiattack. Arrigal makes two shortsword attacks.

Shortsword. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage, and the target must make a DC 15 Constitution saving throw, taking 24 (7d6) poison damage on a failed save, or half as much damage on a successful one.

Light Crossbow. Ranged Weapon Attack: +6 to hit, range 80/320 ft., one target. Hit: 7 (1d8 + 3) piercing damage, and the target must make a DC 15 Constitution saving throw, taking 24 (7d6) poison damage on a failed save, or half as much damage on a successful one.

Curse (Recharges after a Short or Long Rest). Arrigal targets one creature that they can see within 30 feet of them. The target must succeed on a DC 15 Wisdom saving throw or be cursed. While cursed, the target has vulnerability to one type of damage of his choice. The curse lasts until ended with a greater restoration spell, a remove curse spell, or similar magic. When the curse ends, Arrigal takes 3d6 psychic damage.

Evil Eye (Recharges after a Short or Long Rest). Arrigal targets one creature that he can see within 10 feet of him and casts one of the following spells on the target (save DC 15), requiring neither somatic nor material components to do so: animal friendship, charm person, or hold person. If the target succeeds on the initial saving throw, Arrigal is blinded until the end of his next turn. Once a target succeeds on a saving throw against this effect, it is immune to the Evil Eye power of all Vistani for 24 hours.
