Master Assassin A5E

The master assassin ignores the loading quality of light crossbows, and being within 5 feet of a hostile creature doesnt impose disadvantage on the master assassins ranged attack rolls.

As part of making an attack, the master assassin can apply a deadly poison to their weapons (included below). The master assassin carries 3 doses of this poison. A single dose can coat two melee weapons or up to 10 pieces of ammunition.

When the master assassin scores a critical hit against a living creature that is surprised, that creature makes a DC 18 Constitution saving throw. On a failure, it is reduced to 0 hit points. The creature dies if it fails two death saves before it stabilizes.

During the first turn of combat, the master assassin has advantage on attack rolls against any creature that hasnt acted. Any hit the master assassin scores against a surprised creature is a critical hit, and every creature that can see the master assassins attack is rattled until the end of the master assassins next turn.

When the master 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 master assassin deals an extra 28 (8d6) damage when they hit with a weapon attack while they have advantage on the attack, or when the master assassins target is within 5 feet of an ally of the master assassin while the master assassin doesnt have disadvantage on the attack.
