The Lachrimort (COTW Mar. wk 5)
If you're looking for a creature that embodies the phrase "misery loves company," look no further. The Lachrimort is a creature that doesn't want to fight you—it just wants you to sit in the rain and contemplate your failures with it. Unfortunately, its sheer gloom is so potent that it leaks into the weave of fate itself. The Lachrimort is best used as a social encounter or a "hazard" during a journey. It isn't malicious; it might even try to "help" the party by sharing its luck, but its gloomy nature makes that luck highly volatile. If the players are mean to it, it doesn't fight back—it just weeps harder, making the surrounding 30 feet difficult terrain due to the sudden puddles of magical tears.
