Blighted Ice Bat

Hive Mind. The Blighted Ice Bat shares a hive mentality with other Blighted creatures, allowing them to act in unison. If one Blighted creature is aware of a hostile creature, all others in the hive mind are also aware.

Blighted Scourge. Natural weapon attacks by the Blighted Ice Bat carry the Blighted Scourge infection. A creature hit by its bite must succeed on a DC 14 Constitution saving throw or contract the Blighted Scourge.

Keen Hearing. The Blighted Ice Bat has advantage on Wisdom (Perception) checks that rely on hearing.

Frost Aura. The Blighted Ice Bat emits a 10-foot radius of frigid air. Any creature that starts its turn within the aura must succeed on a DC 14 Constitution saving throw or take 7 (2d6) cold damage and reduce its speed by 10 feet until the start of the creature’s next turn. Blighted creatures are immune to this effect.

Icy Death Burst. When the Blighted Ice Bat drops to 0 hit points, it bursts in a wave of cold energy. Each creature within 10 feet must succeed on a DC 14 Constitution saving throw or take 14 (4d6) cold damage and be infected with the Blighted Scourge.

Multiattack. The Blighted Ice Bat makes two attacks: one with its bite and one with its freezing claws.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) piercing damage, and the target must succeed on a DC 14 Constitution saving throw or contract the Blighted Scourge.

Freezing Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (3d6 + 3) slashing damage plus 7 (2d6) cold damage.

Frosty Dive. As a bonus action, the Blighted Ice Bat can move up to 20 feet towards a creature and make one Bite attack.
