Corrupted Wolf Alpha

The wolf has advantage on attack rolls against a creature if at least one of the wolf’s allies is within 5 feet of the creature and isn’t incapacitated.

Aura of the Blight (10 ft.).
At the start of each of the Alpha’s turns, each non-corrupted creature of its choice within 10 ft. must succeed on a DC 12 Constitution saving throw or take 3 (1d6) necrotic damage and have disadvantage on Wisdom (Perception) checks until the start of the Alpha’s next turn.

Death Burst.                                                                                                                                            When the Alpha dies, its body ruptures, releasing toxic sap. Each creature within 10 ft. must make a DC 13 Dexterity saving throw or take 9 (2d8) acid damage.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target.
Hit: 9 (2d6 + 2) piercing damage, and the target must succeed on a DC 13 Strength saving throw or be knocked prone.
If the target is prone, it must also make a DC 13 Constitution saving throw or take 5 (1d10) poison damage at the start of its next turn.

Corrupt Howl (Recharge 5–6).
The Alpha lets out a warped, echoing howl.
Each allied corrupted creature within 60 ft. that can hear it gains advantage on attack rolls and 10 temporary hit points until the end of their next turn.
Each non-corrupted creature within 30 ft. must succeed on a DC 13 Wisdom saving throw or be frightened until the end of its next turn.
