Goblins infected cannot control transformation Opposite of wild lycanthropy, Boogins causes foul spawn to transform into bugbears in the day time and revert at night

Foulspawn generals can usually find places in their armies for bugbears.
Foultongue transformation disease that turns foulspawn into beast during the day and revert back at night less control then lycanthropy or felynthropy barely anyone with the disease can control their transformation
