Aura of Gloom. There is a pervasive aura of permanent mist that wracks at the mind. When a creature comes within 20 feet of the adult gloom dragon or starts their turn within 20 feet they must make a DC 20 Wisdom save. If they fail, they are dampened in spirit and subtract 1d4 on attack rolls, ability checks, and skill checks so long as they remain within 10 feet of the adult gloom dragon. Once they leave the area they can reroll the save and end the effect on a success. On a successful save they become immune to Aura of Gloom for one minute.

Eternal Consumption. Whenever a Gloom Dragon eats a creature of its size or smaller, its souls is trapped in a tomb stone on its back. It takes one minute to eat a corpse and then grow the tomb stone. All information normally found on a tomb stone is found on the tomb stone on its back. The soul cannot be resurrected unless the Gloom Dragon is killed and the tomb stone smashed.
