Special Abilities
Draconic Predator. The ichneumon is immune to a dragon's Frightful Presence and has advantage on saving throws against the breath weapons of dragons.
Evasion. If the ichneumon is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, the ichneumon instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.
Keen Hearing and Smell. The ichneumon has advantage on Wisdom (Perception) checks that rely on hearing or smell.
Mud Armor. If the ichneumon spends an hour applying mud to itself, it can increase its AC by 2 for 8 hours.
Actions
Multiattack. The ichneumon makes three attacks: two with its bite and one with its claws.
Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 20 (4d6 + 6) piercing damage and the target is grappled (escape DC 18). Until this grapple ends, the target is restrained, and the ichneumon can't use its bite on another target.
Claws. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 16 (3d6 + 6) slashing damage.
