Blight Dragon (5e Creature)
From D&D Wiki
Huge dragon, neutral evil
Saving Throws Str +11, Wis +7, Cha +7
Innate Spellcasting. The dragon's innate spellcasting ability is Charisma (spell save DC 15). The night dragon can cast the following spells innately, requiring no material components:
Legendary Resistance (1/Day). If the dragon fails a saving throw, it can choose to succeed instead.
Multiattack. The dragon can use its Nightmarish Countenance. It then makes three attacks: one with its bite and two with its claws.
Bite. Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 19 (2d10 + 8) piercing damage plus 7 (2d6) necrotic damage.
Claw. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 15 (2d6 + 8) slashing damage.
Tail. Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 17 (2d8 + 8) bludgeoning damage.
Nightmarish Countenance. Each creature within 60 feet of the dragon that can see it must succeed on a DC 16 Wisdom saving throw or be frightened for 1 minute. An affected creature 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 saving throw is successful or the effect ends for it, the target is immune to this dragon's Nightmarish Countenance for the next 24 hours.
Shadow Breath (Recharge 5-6). The dragon exhales shadowy energy in a 30-foot cone. Each creature in that area must make a DC 18 Dexterity saving throw, taking 63 (18d6) necrotic damage on a failed save, or half as much damage on a successful one.
The dragon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The dragon regains spent legendary actions at the start of its turn.
Detect. The dragon makes a Wisdom (Perception) check.
Vile arcane rituals can transform night dragon eggs into blight dragon eggs. Blight dragons are far larger than night dragons, and they look like brutishly malformed night dragons. However, blight dragons can breed amongst themselves, giving rise to a new variety of wicked dragon.
Domineering and Vile. Blight dragons lust for power and control, and treat humanoids as little better than chattel to be enslaved or devoured as they see fit. They even see other dragons as potential servants, capturing lesser dragons and forcing them into servitude, and a blight dragon that is especially powerful might even enslave a young chromatic or metallic dragon.
Deep Dragons. Blight dragons prefer to dwell underground in vast caverns, away from the light of the sun, for its touch is anathema to them.
Selfish Conquerors. A blight dragon endlessly seeks to add treasures to its hoard, typically the former belongings of slaves, though it most covets the treasures of enemy nations. A mighty blight dragon might count the gem-encrusted throne of a conquered nation or the magical greatsword of that nation's greatest champion among its most prized possessions, displaying them with pride. It might refrain from devouring a particularly tenacious enemy to have them petrified. It then displays the statue, usually equipping it with its possessions from life, for they see bested foes as the greatest of treasures, sometimes going to great lengths to avoid killing a hated enemy just for the sick pleasure of mocking them.
A Blight Dragon's Lair
Blight dragons lurk underground, away from the sunlight. A blight dragon's lair is a foul cave or ruin that the sun's light cannot reach and where it can watch over its slaves and nearby humanoid settlements. Throughout the lair, the remains of the dragon's meals can be found, though any treasure they carried is spirited away by the dragon and kept somewhere safe, like a large cavern that can only be reached by flying creatures or massive vault protected by underlings.
On initiative count 20 (losing initiative ties), the dragon takes a lair action to cause one of the following effects; the dragon can't use the same effect two rounds in a row:
The region containing a blight dragon's lair is warped by the dragon's magic, which creates one or more of the following effects:
If the dragon dies, these effects end immediately.
Variant: Blight Dragon Shapechangers
Some blight dragons have the ability to change their shapes to appear humanoid. In a humanoid form, the blight dragon invariably looks brutish and aged, and those around it are filled with a sense of unnatural dread. Such a blight dragon has the following action option.
