Keen Smell. The bear has advantage on Wisdom (Perception) checks that rely on smell.

Keen Sight. The bear has advantage on Wisdom (Perception) checks that rely on sight, but has a vulnerability to radiant and light based spells that catch it unprepared.

Poison Resistance. The bear takes half damage on any attack that does poison damage.

Deafness. The bear is immune to attacks or effects based on sound.

Multiattack. The bear makes two attacks: one with its bite and one with its claws.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage.

Claws. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (2d4 + 2) slashing damage. On a successful hit, the creature must make a DC 14 Constitution saving throw. On a failed save, the creature takes 7 (2d6) poison damage and becomes poisoned. On a success, the creature takes half as much damage and isn't poisoned. A creature poisoned by this effect can repeat the save at the end of each of its turn, ending the effect on itself on a success. While poisoned by this effect, a creature can't regain hit points.
