Obmi

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

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

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