Traits

Magic Resistance. The Bukavac has advantage on saving throws against spells and other magical effects.

Trampling Charge. If the Bukavac moves at least 20 feet straight toward a creature and then hits it with a Gore attack on the same turn, that target must succeed on a DC 18 Strength saving throw or be knocked prone. If the target is prone, the Bukavac can make one Claw attack against it as a bonus action.

Actions

Multiattack. The Bukavac makes three attacks: one with its Gore and two with its Claws.

Deafening Roar (Recharge 5–6). The Bukavac emits a terrifying roar audible within 300 feet. Each creature within 60 feet of the Bukavac that can hear it must make a DC 16 Constitution saving throw. On a failed save, a creature takes 27 (6d8) thunder damage and is stunned until the end of its next turn. On a successful save, the creature takes half as much damage and isn't stunned.

Fog Cloud (3/Day). The Bukavac can cast the fog cloud spell (as a 3rd-level spell, spell save DC 13), requiring no material components.

Reactions

Whirlpool Defense. When the Bukavac is targeted by a ranged attack while in water, it can create a whirlpool around itself. The attack has disadvantage, and the Bukavac moves up to half its swim speed without provoking opportunity attacks.

Legendary Actions

The Bukavac can take 2 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature's turn. It regains spent legendary actions at the start of its turn.

Move. The Bukavac moves up to its speed without provoking opportunity attacks.

Claw Attack. The Bukavac makes one Claw attack.

Water Summons (Costs 2 Actions). While in contact with a natural body of water, the Bukavac magically summons one water elemental or 1d4 water weirds. The summoned creatures appear in unoccupied spaces within 60 feet of the Bukavac, act on its initiative, and obey its commands. They remain until destroyed or until the Bukavac dismisses them as a bonus action.

Lair Actions

When fighting inside its lair (a large body of water like a lake or swamp), the Bukavac can invoke the ambient magic to take lair actions on initiative count 20 (losing initiative ties):

Churning Waters. The Bukavac causes the water within 60 feet of it to become difficult terrain for other creatures until initiative count 20 on the next round.

Misty Shroud. A thick fog rises around the area within 120 feet of the Bukavac, as per the fog cloud spell (no concentration required), lasting until initiative count 20 on the next round.

Lore

A monster with slimy skin, a huge mouth, a long tail, and massive, twisted deer antlers.

Bukavac is a demonic creature described in legends as a four or six-legged monster covered in slimy skin with a long tail. Additionally, it has huge, highly twisted and curled antlers on its head. Visually, it most closely resembles a bull.

According to folk beliefs, it lives in large bodies of water—most often in lakes or swamps—and its home is considered to be a shelter made of stones that it constructs itself.
