Dawn of the Old Gods: Tyranny of Dragons
Green Drakes Abomination
The Cult of the Dragon has been creating drake abominations by having a willing initiate of the cult consume a liter of dragon blood. If you survive the ritual one potential outcome is your body starts to transform and take on the physical properties of the type of dragon whose blood you consumed. This is a product of a cultist willingly drinking green dragon blood.
This creature is often referred to as an Ambush Drake.
