Archfiends (Redux)

Archfiends
Archfiends are a type of demon that live in the "Wild Dimension". They're known for their ability to shapeshift, and can take on many forms. Their most common form is a giant wolf-like creature with bat wings and glowing red eyes. Some archfiends have been seen as humanoids or even as animals like cats or dogs. The more powerful archfiends have shown the ability to transform into other creatures such as dragons, centaurs, and even giants. It's unknown what causes an archfiend to change its shape, but it seems to be linked to emotions. When they feel happy, they'll become something cute. However, when they're angry, they'll turn into fearsome monsters.

The only way to kill an archfiend is by using a holy weapon or spell. Even then, it's not guaranteed to work. Most people who try to fight them end up dead themselves. There's also no way to capture one alive. Archfiends are too strong for anyone to handle, and there's no telling how long they would survive if captured. If you see an archfiend, run away!
