Cinder-Wing Wyvern - AI-generated fantasy Monster

Cinder-Wing Wyvern

Local legends say these wyverns were once common dragons whose blood was thinned by a great fire curse. Now they are husks of heat and rage, unable to produce true flame but mastery of the suffocating aftereffects of fire.

Smoldering Haze. The wyvern is surrounded by a 10 foot radius of light smoke. This area is lightly obscured to others. While in heavy fog or smoke, the wyvern has advantage on Stealth checks.
Soot Vision. The wyvern's vision is not obscured by smoke or fog.

Actions

Multiattack. The wyvern makes two attacks: one with its bite and one with its stinger. While flying, it can use its claws in place of one of these attacks.
Bite. Melee Weapon Attack: to hit, reach 10 ft., one creature. Hit: 11 () piercing damage plus 3 () fire damage.
Claws. Melee Weapon Attack: to hit, reach 5 ft., one creature. Hit: 13 () slashing damage.
Stinger. Melee Weapon Attack: to hit, reach 10 ft., one creature. Hit: 11 () piercing damage. The target must make a Constitution saving throw, taking 24 () fire damage on a failed save, or half as much damage on a successful one.
Searing Ash Breath (Recharge 5-6). The wyvern exhales a 30 foot cone of abrasive, searing ash. Each creature in that area must make a Dexterity saving throw. On a failure, a creature takes 21 () fire damage and is blinded until the end of its next turn. On a success, the creature takes half damage and isn't blinded.

Reactions

Ash Cloud Escape. When the wyvern takes damage, it can beat its wings to release a burst of soot. It can move up to half its fly speed without provoking opportunity attacks.

Notes for the game master

The high fire damage on the stinger represents the searing heat injected into the wound rather than biological poison.

Tactics

  1. Opening

    The wyvern begins high in the fog, using its Ash Breath to blind as many targets as possible before diving.

  2. Mid-fight

    It focuses on a single blinded target, using Multiattack and its fly speed to stay out of reach of grounded melee fighters.

  3. End of the fight

    If reduced below 30 HP, it uses its Ash Cloud Escape to gain distance and retreats to its lair.

  4. Retreat

    Extremely defensive of its nest; it will fight to the death if the battle occurs within the Scorched Hives.

How it fights

Uses Smoldering Haze to remain hidden until the last moment.
Targets spellcasters first to disrupt concentration and light sources.
Stays 10 feet up using reach attacks to avoid short-range counters.

Who it attacks first

Concentrating Spellcasters
Archers
Frontline Fighters

Works well with

Ways to avoid a fight

The wyvern can be distracted by large quantities of high-carbon material like coal.
A druid could attempt to soothe its scorched skin with magically created water or ice.

Ecology

This wyvern has scales that resemble split, charred logs with embers glowing in the cracks. Its wings are tattered at the edges, constantly shedding a trail of thick grey smoke. Instead of the usual wyvern green, its skin is the color of cooling magma and volcanic glass.

Behavior

It is an opportunistic hunter that relies on stealth. It circles high above the heavy fog of the Scorched Hives, diving only when it can confirm a target is isolated. It is highly territorial and views any light source as a challenge to its dominance.

How it lives

Cinder-Wing Wyverns feed primarily on charred remains. They often 'cook' their prey by hovering over them and beating their wings to fan flames before descending to eat. Their digestive systems require charcoal and minerals found in volcanic ash.

Lair

The Scorched Hives, a series of vertical basalt tubes that naturally vent heat and sulfurous gases.

Habitat
Volcanic outskirts, burnt forests, and foggy canyons.

Signs that it is near

Hot, soot-covered bones
Trees with tops snapped off and blackened
A lingering smell of sulfur and wet ash
Sudden, localized thickening of fog

What drives it

To protect its nest in the Scorched Hives and eliminate any competitors for food in the foggy lowlands.

After the fight

Once defeated, the local fog begins to lift as the wyvern's smoke-generating presence vanishes. The players may find a map to the Scorched Hives on a partially digested corpse.
