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

Sneak Attack. Once per turn, the blobfish 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 blobfish that isn't incapacitated and the assassin doesn't have disadvantage on the attack roll.
