Traits

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

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

Sneak Attack (1/Turn). Torbit deals an extra 14 (4d6) damage when it 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 the assassin that isn't incapacitated and the assassin doesn't have disadvantage on the attack roll.

Amphibious. <$title_short_name$> can breathe air and water.

Swamp Camouflage. <$title_short_name$> has advantage on Dexterity (Stealth) checks made to hide in swampy terrain.

Standing Leap. <$title_short_name$>'s long jump is up to 20 feet and their high jump is up to 10 feet, with or without a running start.

Actions

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.

Lore

Trained in the use of poison, assassins are remorseless killers who work for nobles, guildmasters, sovereigns, and anyone else who can afford them.
