I’ve been running an Outgunned Adventure! campaign set in 1920s China. The most recent threat was a huli jing — a fox spirit. The creature is popular in Chinese, but also Korean, Japanese, and Vietnamese myth. These usually immortal creatures have nine tails in fox form and can shapeshift — usually into beautiful young women who seduce scholarly or important men to steal their knowledge and life essence. (You can guess how…) They can be driven off by catching them in fox form and cutting off their tails, or in human form by getting them drunk. Alternately, they can be driven off if you know the name by writing it on paper, burning the paper, and mixing the ashes in tea.
