Sloth demon

Sloth Demons can take up different forms (their natural form is the same of Shades) and are typically unwilling to fight unless pressured or threatened. That's not to say that they pose no threat to one who encounters them. The Sloth Demon feeds off of laziness and will secretly influence to those of its beliefs without direct confrontation. These Demons are some of the more powerful malicious spirits, but lacking the urge to use their power makes them far less encountered across the Veil and The Fade.

Strategy
Though combat with Sloth Demons are rare, they are to be treated like stronger Desire Demons. Because you encounter only the Sloth Demon during the fight using a Misdirection Hex will significantly lower the amount of damage being taken allowing a quick and easy victory.
