The Beer Faerie is a frog-like fae in technicolor, that 'walks' on its hind legs and stands about 3-4' high. They wear ill-fitted and stolen clothing. Their CR varies by level of inebriation, time of day, weather, and so on. Mostly, they're known for staring uncomfortably without blinking, and following the person around.
Beer Fae may only be seen by the inebriated, though may at times, make themselves visible to one person or the other, presumably to mess with the drinker's mind.
There is a roughly 15 percent chance of encountering them after drinking.
The true name of these creatures are unknown--the simple name is given to them from warriors and sailors, who share tales of them.
