Special Traits

• Immutable Form. The death barque is immune to any spell or effect that would alter its form.
• Magic Resistance. The death barque has advantage on saving throws against spells and other magical effects.
• Siege Monster. The death barque deals double damage to objects and structures.
• Turn Resistance. The death barque has advantage on saving throws against any effect that turns undead.

Actions

• Multiattack. The death barque makes three attacks: one with its bite and two with its tail smash.
• Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 21 (3d10 + 5) piercing damage.
• Tail Smash. Melee Weapon Attack: +9 to hit, reach 15 ft., one target. Hit: 15 (3d6 + 5) bludgeoning damage and must succeed on a DC 17 Strength saving throw or be knocked prone.
• Shrapnel Burst. The death barque launches a ball of bone shards from its tail at a point it can see within 120 feet of it. Each creature within 10 feet of that point must make a DC 17 Dexterity saving throw. On a failure, a creature takes 28 (8d6) piercing damage and is blinded for 1 minute. On a success, a creature takes half the damage and isn’t blinded. A blinded creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
• Necrotic Breath (Recharge 5-6). The death barque exhales a dark cloud of necrotic energy in a 60-foot cone. Each creature in that area must make a DC 17 Constitution saving throw, taking 54 (12d8) necrotic damage on a failed save, or half as much damage on a successful one.

About

The first bone colossus was deployed in anger where it proved decisive in bringing a siege to a rapid and favorable conclusion for the undead armies.

The darakhul have long practiced necromancy, using the corpses and bones of Underworld denizens to create new undead servants and devise powerful war machines to aid in their conquest of the subterranean lands.
