SPECIAL TRAITS

• Charge. The buggane moves at least 20 feet straight toward a target and then hits it with a Gore attack on the same turn, the target takes an extra 10 (3d6) damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be knocked prone.
• Control Weather (1/Day). The buggane can cast the control weather spell, requiring no material components and using Wisdom as the spellcasting ability.
• Death Throes. When the buggane dies, it throws its head at a point it can see within 120 feet of it. Each creature in a 10-foot-radius sphere centered on that point must make a DC 18 Dexterity saving throw. The sphere spreads around corners. A creature takes 35 (10d6) fire damage and 35 (10d6) necrotic damage on a failed save, or half as much damage on a successful one.
• Discern Lie. The buggane discerns when a creature in earshot speaks a lie in a language the buggane knows.
• Harmed by Running Water. The buggane takes 20 acid damage if it ends its turn in running water.
• Keen Hearing and Smell. The buggane has advantage on Wisdom (Perception) checks that rely on hearing or smell.
• Siege Monster. The buggane deals double damage to objects and structures.
• Tunneler. The buggane can burrow through solid rock at half its burrowing speed and leaves a 10-foot-diameter tunnel in its wake.

ACTIONS

• Multiattack. The buggane makes three melee attacks: one with its Bite, Gore, and Claws in buggane form, three with its Gore in cow form, three with its Bite in mastiff form, or three with its Claw in humanoid form.
• Gore (Buggane or Cow Form Only). Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 17 (2d8 + 8) piercing damage or 26 (4d8 + 8) piercing damage when enlarged.
• Bite (Buggane or Mastiff Form Only). Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 8) piercing damage or 22 (4d6 + 8) piercing damage when enlarged. If the target is a creature, it must succeed on a DC 11 Strength saving throw or be knocked prone.
• Claw (Buggane or Humanoid Form Only). Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 17 (2d8 + 8) slashing damage or 26 (4d8 + 8) slashing damage when enlarged.
• Spit Tooth. Ranged Weapon Attack: +14 to hit, range 60 ft./120 ft., one target. Hit: 15 (3d4 + 8) piercing damage or 23 (6d4 + 8) piercing damage when enlarged.
• Change Shape. The buggane magically polymorphs into a Medium mastiff, Large cow, Medium humanoid, Medium cloud of mist, or back into its true form. Other than its size, its statistics are the same in each form. Any equipment the buggane is wearing or carrying is absorbed by the new form. If the buggane dies, it reverts to its true form. While in mist form, the buggane can’t take any actions, speak, or manipulate objects. It is weightless, has a flying speed of 20 feet, can hover, and can enter a hostile creature’s space and stop there. In addition, if air can pass through a space, the mist can do so without squeezing, and it can’t pass through water. It has advantage on Strength, Dexterity, and Constitution saving throws, and it is immune to all nonmagical damage.
• Terrifying Howl (Recharge 6). The buggane howls. Any Beast or Humanoid within 300 feet of it must succeed on a DC 15 Wisdom saving throw or be frightened of it for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a target’s save is successful or the effect ends for it, the target is immune to any buggane’s Terrifying Howl for the next 24 hours. Enlarge (Recharges after a Short or Long Rest). For 1 minute, the buggane magically increases in size, along with anything it is wearing or carrying. While enlarged, the buggane is Gargantuan, doubles its damage dice on Strength-based weapon attacks (included in the attacks), and makes Strength checks and Strength saving throws with advantage. If the buggane lacks the room to become Gargantuan, it attains the maximum size possible in the space available.

ABOUT

This monstrous fiend is covered in a mane of coarse black hair, with eyes like torches, wicked bull horns, and glittering tusks.

Bugganes are the angry spirits of those who were murdered or died unjustly, sent back through Infernus to extract their revenge on all who cross them. Enraged by their ill-treatment, they become bullies and tricksters, bedeviling innocents and clergy in particular.

Bugganes can take a dizzying variety of forms. In mastiff form, they appear as large shaggy dogs with glowing red eyes. In humanoid form, they appear as hairy clawed men. In cow form, they appear as black bulls. When attempting to sneak into places, they turn into mist form.

Bugganes prefer to inhabit old ruins and dense forests. These locations offer them cover and allow them to remain undisturbed unless provoked. Legends suggest that bugganes are magical creatures that can’t cross running water or set foot on hallowed ground.

The buggane is infamous for its destructive nature, particularly towards structures, especially churches. It enjoys tearing the roofs off churches and causing havoc among human settlements. If it is about to die, it will not hesitate to tear off its own head as a deadly projectile, targeting and throwing it at its victims with remarkable accuracy.

Bugganes are known to be mischievous and chase and frighten people for amusement. They take pleasure in causing terror and fear in their prey. They do respect those who tell the truth however.

On Infernus, bugganes can be found in the Woe Wood of the Seventh Circle, often roaming in hound form. When not roaming the Wood, they can be found leading infernal minotaur patrols.
