Actions/Abilities/Traits: (D&D 5e)
Action
Bite
Melee Weapon Attack: +4 to hit, reach 0 ft., one target. Hit: 1 piercing damage plus 1 fire damage.
Action
Fire Breath (Recharge 5-6)
The pyrausta exhales fire in a 10-foot cone. Each creature in that area must make a DC 9 Dexterity saving throw, taking 2 (1d4) fire damage on a failed save, or half as much damage on a successful one.
Action
Spark
The pyrausta ignites a flammable object it can see within 30 feet. If the object is held or attended by a creature, the creature may make a DC 11 Dexterity saving throw; on a success, the object is unaffected.
Special
Flyby
The pyrausta doesn't provoke opportunity attacks when it flies out of an enemy's reach.
Special
Heart of Flame
A tiny spark of flame that acts as a pyrausta's heart beats within its chest. Whenever a pyrausta takes cold damage, including damage from environmental cold, its little heart stalls. Its regeneration does not function until the end of its next turn and it must make a DC 11 Constitution saving throw. On a failed save, it must use its next action to re-ignite its heart, or it will take 1 point of cold damage at the end of each of its turns until it does.
Special
Regeneration
The pyrausta regains 1 hit point at the start of its turn if it has at least 1 hit point.

Special
Heart of Flame (Ex)
A tiny spark of flame that acts as a pyrausta's heart beats within its chest. Whenever a pyrausta takes cold damage, including damage from environmental cold, its little heart stalls. It loses its fast healing and breath weapon, gains the staggered condition, and takes 1 point of damage each round. This continues until it is exposed to a source of flame that would normally deal fire damage or until it successfully uses its spark spell-like ability to reignite its heart (doing so requires a successful DC 11 concentration check because of the ongoing damage).
