Half-Shadow Dragon Assassin A5E

During the first turn of combat, the assassin has advantage on attack rolls against any creature that hasnt acted. On a successful hit, each creature of the assassins choice that can see the assassins attack is rattled until the end of the assassins next turn.

As part of making an attack, the assassin can apply a dangerous poison to their weapon (included below). The assassin carries 3 doses of this poison. A single dose can coat one melee weapon or up to 5 pieces of ammunition.

When the assassin makes a Dexterity saving throw against an effect that deals half damage on a success, they take no damage on a success and half damage on a failure.

The assassin deals an extra 21 (6d6) damage when they hit with a weapon attack while they have advantage on the attack, or when the assassins target is within 5 feet of an ally of the assassin while the assassin doesnt have disadvantage on the attack.
