Summary[]
An Outlier is a data point that is outside the consistent grouping in a set.
In Power scaling, Outliers refer to feats that cannot be explained by the current Meta, with high ends usually just called outliers and low ends commonly called antifeats. Outliers are not a disqualification for feats, but they are a category that things should go in as a sort of to-do list. The best reading of a character would be able to explain the outlier as consistent in some way, shape, or form and thus make it not an outlier.
