Rool

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

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

Rool 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 Rool that isn't incapacitated and Rool doesn't have disadvantage on the attack roll.

1/TURN

When reduced to 0 hit points, Rool drops to 1 hit point instead (but can't do this again until they finish a long rest).

When they score a critical hit, Rool can roll one of the weapon's damage dice and add it to the extra damage of the critical hit.

Rool makes two shortsword attacks.

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.

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.
